Cisco LAN :: 3550 Simulating Small Branch Office In Lab Network
Jun 6, 2012
I have to setup what seems to be a very basic configuration, but it doesn't work. In our lab there is a cluster of switches with a 3550 that does all the routing for vlans. I need to simulate a sort of a small branch office that has one connection to the outside world (the lab network). [code] From the router I can ping any host on vlan 230 and other vlans,I can also ping the pc connected to e0/1.However from the PC I can only ping 192.168.1.1(e0/1) and 172.26.230.150 (e0/0) [code]

My current set-up is: my laptop connects to the coaxial outlet with a cable so I can access the internet. So I can't really bring it somewhere else since the cable is short.
Now, I am planning to buy 2 more computers and a printer. The printer will be shared by all 3 computers. what else I need to buy (modem?? wireless router??) and what type. I also request that you let me know how to set it up. Of course, I will follow the manufacturer's instructions.

I have been tasked with the technology update of our office and have have MAJOR questions which I hope can be answered here, so here goes;
First a little history, I have an electronics degree and a certificate in computer technology, so computers are not something new to me, however networking IS.I have a VERY LIMITED budget to work with, which I'm sure is not unheard of before, with the following equipment already available:
1 MFP currently on lease connected via network
3 totally junk PCs running 3 different versions of Windows from XP to 7
A DSL internet connection
A wireless router
A wired 8 port switch
What I would like to do is begin with a basic server, 7 clients, shared internet on all machines (including external via login), An MFP, at least 1 NAS for data storage, 1 NAS for backup of all drives.

What are the best network engineering practises for a small/medium sized office?Currently I have set it up like this:The top floor has all the sales people, each desk has a hub underneath which connects all computers at that desk together, and the hum is connected to a switch under the floor. There are about about 8 desks each with about 4 computers, so 8 hubs.They all go into a 10/100 switch, which is then connected to an 1gb switch on the bottom floor via a 1gb port on the top floor switch, via a cat6 cable.We then have internet > modem > router > the 1gb switch. Our main server is also connected to that switch along with all the computers for the ground floor, except these computers have 1gb switches under the desks instead of hubs. The main server is the DHCP, DC, DNS and file server. We have also setup another server which acts as a backup DC and is also a DNS server.Is there anything wrong with this configuration? We have been having problems with the router losing connection to the internet and warnings on the main DNS server.

My office just moved to a bigger location, and we are having trouble with network connectivity.
Current layout: Modem --- Wired-----> 2wire 5012NV ------wired/wireless----> PCs
The 2wire is at one end of the office, and PCs at the other end experience poor wireless connectivity.I'm thinking of using a spare WRT54G2 in "bridged" mode, to extend the Ethernet, and wireless of the main router.
For wired bridging, I understand that that the WRT54G2 will do, is act as a "port multipler", where 1 port from the 2wire can be multiplied into 4. I also want the wrt54g2's wireless to extend the Ethernet connection (not extend the wireless connection).

I have a cable modem in the basement and ethernet lines to two offices upstairs.I have a 4-port wireless router and a 5-port switch. I have a computer in each office and a NAS in one of the two offices.There is no direct wiring between the offices. I want to have internet access and access to the NAS from both offices. Will the following configuration work without having to go to Static IPs? 1) Modem01-> Router01->Switch01->Computer01; 2) Modem01->Router01->Switch01->NAS01; 3) Modem01->Router01->Computer02. If not, what needs to change?

XYZ Corporation currently employs eight people but plans to hire 10 more in the next four months. Users will work on multiple projects, and only those users assigned to a project should have access to the project files. You’re instructed to set up the network to make it easy to manage and back up. Would you choose a peer-to-peer network, a server-based network, or a combination of both?

I am trying to set our VPN connection to route to our branch office from a VPN Client. So far I did not succeed and at this point I am stuck.At our office we have a VPN Server which enables VPN Clients to connect to our main office with an IP Range of 192.168.104.0 with subnet 255.255.248.0 and a branch office with a IP Range of 192.168.25.0 and a subnet 255.255.255.0Internally on the LAN the routing is done by our firewall, which acts as DHCP and Default gateway. It connects the 2 LANs by a leased line.When I ping an IP address in our branch office from our main office I get a reply.
Now when a VPN client connects it gets a IP Address in the range of the main office from our firewall and the client can connect to all computers in the main office network. However if i try to connect to a computer in the branch office it does not work.I tried a static route in the Routing and remote access Server (which is Windows Server 2003 R2) and I tried adding a static route to the DHCP settings on the firewall. In both cases it does not connect from the VPN Client to the branch office.Searching the internet, since the examples are all based on a setup with a RAS Server on both networks. The LANs are already "integrated"/"physicly connected" trough the routing on our firewall and its leased line.
I also tried settings on the VPN Clients machine. Settings like "Use gateway in remote network" on or off and tried adding static routes. This did not work, since the Default gateway I must use is not on the same range as the home network and returned an error trying that.What I noticed is that the VPN Client gets a route which uses the VPN CLient IP as default gateway. Makign a static route like that will work (I think), but since the IP addresses for the VPN clients are obtained through DHCP and can vary each time, there is no way (i think) to automate adding a route with, for example, a batchfile that I could give to the employees connecting trough VPN because of the variable IP.

I'm trying to network a small office and have the following devices:
SMCD3G Cable Modem
Belkin Play N600 Router
Digi Mil-H1130 8 Port Ethernet SOHO Hub
Hubbel Cat5 Patch Panel (goes up to 12)
We're replacing our DSL line with a Cable line. Our DSL was a one piece wireless router/modem. When it was installed, it was inside our office, next to the server, and plugged into Wall Jack 1 for all the other computers to connect to. Our server plugged into this modem/router. We didn't have the Belkin Router at the time. The Patch Panel wires went into the Hub behind our office and everything was fine.
The cable modem is now next to the Hub and Patch Panel. I bought the router since we didn't have the wireless feature that the DSL had and everyone I spoke to said I need a router to set up the office. I ran one of the LAN lines from the modem into the Router where it says Modem (WAN). From the Router, I ran the line 1 (LAN) into the Hub. (Does the number matter if nothing is plugged into it in our office?) No computer is able to connect to the internet except my laptop which connects wireless. It works fine.
Another problem. We have a server computer that's Unix based. In order for anyone to connect to the server to access the office software used, the IP address of the router must be 192.9.2.1 or the computer your using won't connect via Multiview 2000 Terminal Emulator. I can't connect to the server because the IP address of the router is still 192.168.2.1. I don't know where I have to go in the router settings to change it. I've tried a few spots and it tells me the IP address is invalid. The settings I had with the DSL modem/router were:
Modem IP address - 192.9.2.1
Subnet Mask - 255.255.255.0
DHCP Start Address - 192.9.2.100
DHCP End Address - 192.9.2.150
It's not like I need to run wires. Everything is set. If something is plugged into a wrong spot, I can switch it.
Additional info:
There are 4 computers in the office and 8 numbered wall jacks.
Server computer - Wall jack 8 (IP address of this machine - 192.9.2.25)
XP Machine 1 - Wall jack 4 (can't connect to server! No internet.)
XP Machine 2 - Wall jack 1 (Is able to connect to the server! No internet.)
Win CE Machine - Wall jack 9 -
I assume. I have a wire that goes through the wall on this machine and it isn't marked. (Rarely used so not sure about server connection)
Wireless Windows7 laptop - connects to the internet fine since it bypasses all these wires. Can't connect to server.
Under the DHCP client list, only 2 computers are listed. The one that has internet is my computer. The other computer listed is wall jack 4 and that has internet now.
my computer - 192.9.2.2
wall jack 4 - 192.9.2.3
The router IP is 192.168.2.1 and the Cable Modem is 10.1.10.11. If I type either number into my web browser it will take me to the router setup page. I don't know where/how to check if it's only one device acting as DHCP. What I want to do is be able to get online with all the computers as well as have access to the software on the server through the office wall jacks. In order to do that I need the router IP address to be 192.9.2.1 and then I'd be able to connect to it.
Right now, one computer is able to connect to the server via hard wire but can't connect to the internet.Another computer is able to connect to the internet via hard wire but can't connect to the server.My laptop can connect wireless to the internet but not the server. In a perferct world, all the computers should be able to connect to both the internet and the server. Right now, it's one or the other with both hard wired machines and I don't know why. Is there a wire not in the hub right? Is a patch panel wire plugged into the wrong port of the hub? I don't know what's supposed to go where. tell me "wire X from the modem goes to Port Z of the router, and Wire Y from the the router goes to number V on the Hub, and that wire goes to number T on the patch panel for the Port number R in the office to work..." I'll try it.
Then I think all I need to do is change the router's IP address to 192.9.2.1 and everyone should be able to connect to the server through the Multiview 2000 Terminal Emulator.When I tried to change the IP address on the router it's telling me it's not valid. Under LAN settings it says 192.168.2.1 - when I try to change it to 192.9.2.1 it tells me LAN IP address is invalid. I clicked on More Info below that in the router page and a pop up gives me info. It says:
The "IP address" is the Internal IP address of the Router. To access the advanced setupinterface, type this IP address into the address bar of your browser. This address can be changed if needed. To Change the IP address, type in the new IP address and click "ApplyChanges". The IP address you choose should be a non-routable IP. Examples of a non-routable IP are:
192.168.y.x (where y is anything between 0 and 255, and x is anything between 1 and 254.)
10.y.y.x (where y is anything between 0 and 255, and x is anything between 1 and 254.)
172.z.y.x (where z is anything from 16 to 31, and y is anything between 0 and 255, and x is anything between 1 and 254.)

I have a problem with a branch office setup, and I can't for the life of me think of what the problem is.I have a remote office setup, using an ASA 5505 that is set up to establish an easy vpn connection to the central network. The connection at the branch office is a 20/5 cable modem, the central network has a 25/25 fiber connection.
The issue I have is this. Wired clients work fine at this branch office, at least 95% of the time. I have a lightweight AP there that can come up and join the controllers at the central network, no problem. I haven't done anything with H-REAP because there are really no resources locally they need that would allow them to do their work, so all traffic is tunneled back to the WLC.
Wireless clients can authenticate to the AP, and I can get 15-20ms ping responses from them all day. Latency never comes close to the 600ms proposed limit with CAPWAP. Yet, for some reason the performance of the clients is problematic. Webpages will frequently not load correctly, they experience some freezing, and with one application we use - it refuses to load completely.If we bring these same computers to an AP connected to our central network, on the same SSID, they work flawlessly.
Something about this particular location is causing a lot of grief for our users.For what it's worth, we are running WCS 7.0.230.0 and the WLCs are on 7.0.116.0. The ASA is running a pretty basic configuration, pretty much out of the box with the easy vpn configuration entered.

We have AT&T Managed MPLS service are our datacenter and our branch office locations. AT&T has provided the routers and simply give us an ethernet connection. We also have ethernet connectivity to the internet through our datacenter...with our network being protected by an ASA 5520.Each branch location has a 29xx series router (voice gateway) and switching gear attached to their AT&T MPLS router. Some of our branches also have 3rd party cable internet service with an ASA 5505 to protect it from the internet. What I'd like to do is better utilize this cable modem/ASA5505 setup. Right now, if there were an outage, I would be connecting manually to the remote location to change static routes to point to the cable link and to configure a VPN tunnel between the remote and our DC.

I've followed Watchguard's instructions for configuring a Branch Office VPN connection, and I'm unable to connect. I have configured the Watchguard gateway to accept remote-to-local connections and put in the Watchguard's public IP address as the local connection, and the WRVS4400n's public IP as remote.The Linksys has the local VPN group configured as 192.168.0.0./24 and the remote gateway as the Watchguard's public IP Address.When I connect it remains "down" and I"m receiving errors saying it could not authenticate. I have the passphrase the same on both sides with 3DES and SHA1 configured.Does the WRVS4400n support this type of VPN configuration or am I wasting effort?

I am preparing to move two branch offices from a point to point T1 connection to Century Link Metro Ethernet.Currently my branch locations connect to my HQ 7204 router via a channelized DS3. I have a 4507R at HQ that I will connect the ME circuit to.We will also be moving our Internet connection on the ME circuit.Our service provider Clink will hand me a single Ethernet handoff for the Internet and branch office connections. For the first phase I will connect one branch office using ME. Once that is in place and tested we will move another office and so on. Then our final step is to move our web connection to the ME circuit.Each branch office has their own unique voice and data subnet. They each have a 2801 router and a 3560 switch. The routers are MGCP gateways with only one PSTN connection, a POTs 911 line on a FXO port.
So my questions are;
1 - Should I connect the ME directly in to the 3560 at the branch offices or use the Fa0/1 on the 2801? Fa0/0 is currently connected to the 3560.
2 - On my 4507R at HQ how will I configure the ME switch port? As a dot1q trunk port?
3 - Given that ME is basically a LAN connection will I have to re IP the branch office? HQ is 10.10.1.x/24. Branch is 10.10.166.x/24 (data) 192.168.166.x/24 (voice).
4 - On the 4507R will I need to configure a vlan interface for each branch subnet?
I attached two network diagrams. One represents our current topology (MEexisting) and the second represents the new ME circuit changes (MEprojected).

I am trying to configure access to several remote offices for users who VPN into our main datacenter. The datacenter has a 5520, and the branches are connected through IPSec L2L VPNs. Branches all have 5505 or 5510's. Remote users use IPSec via the Cisco remote Client. Remote access into our data center works, and the L2L VPNs are perfect...just now that i need remote users to access the branches after Remote access VPNing (for support) i cant get that part to work.

I'm setting up a wireless network for a small office with 25 people with approx. 15 on wireless at any time. The office is very long and skinny so I'm looking at a cluster of WAP321's. I'm hoping these will save a ton of money versus buying a controller and more expensive access points.
How do these work for roaming? I tried a search but I've found descriptions of them not roaming at all and descriptions of them roaming but you have to do some kind of pre-authorization right up to they roam with no user interaction, they just roam.
I need the users to be able to roam around the office with no interruption. I don't want to install these and have to rip them out later and put in new ones and a controller. How to find out if the WAP321's will work for roaming.

We have used two Cisco RVS4000 to create the IPSec VPN between the main office and the branch office. The main office has SBS 2008. There is a Windows Server 2008 as the domain controller in the branch office. One branch office user has a laptop which is not in the domain, but his exchange account is set up in the Outlook. When he connects the laptop to the branch office network, he cannot connect to the exchange server and get the emails. Is there any configuration to set up in the router, server or Outlook?

I'm on a limited budget, ASA 5510 with Security Plus License can give me this but its a bit expensive.Is there something else that you guys can recommend. ISR maybe?

Our Headquarter (asa 5510) is running a site to site vpn connection with a Branch office (router 2811). All remote users are accesing the internet through the VPN and also accesing headquarter file servers.I want to know if there is a way for some remote users to be able to use the vpn for accesing the file servers but to access the internet through the branch office. The rest of the remote users will be still accessing the internet through VPN.

Right now every computer is connected through a workgroup and some computers are sharing files to everyone and some need a login to share other files. I want to run a main server where all the files are on that computer and have it share all the files to everyone else on the network. I'm not too familiar with Windows workgroup networking and file sharing.I want to have certain files accessible to certain computers and certain files accessible to everyone on the network. I'm under the impression that I have to have the main server with all the business documents. Then create separate accounts on the server and hand them out to each individual computer. After, go to each document and specify who can access what with read/write. Can I share some files to everyone and have certain files limited to other computers at the same time? How would someone access the shared files when you need a login and will this login conflict with files shared to everyone and files shared to certain people. I remember on my small business network I need a login for certain computers because it is shared to only certain people then how would I access the files shared to everyone when I have to login to see the server files to begin with?

I can't seem to figure out which one I should go for. I'm thinking Kaspersky would have greater security but I'm not familiar with AVG's server level security.I don't need all the bells and whistles such as file encryption or password storage. I'm simply after a really strong AV for the server. Another one is VIPRE although I've heard it can take a while to configure it unlike Kaspersky which is pretty straight forward.

Now I am trying to implement ICMP redirecting attack by using Intercepter program. Diagram of my netwok you can see on enclosed picture (Schema.jpg). Through Intercepter program I generate packets ICMP redirect (ICMP type 5), which are successfully sent from PC Attacker, but these packets do not arrive to PC Victim and Warshark shows me messages „ Destination Unreachable (Host Unrecheable).“ When I use instead of Cisco switch non Cisco switch (for example: Edimax) or hub, ICMP redirects packets arrive to PC Victim and I can continue in the attack?

I can use cable modem that my ISP gave to me: this modem acts as bridge so I can use router with FE-based WAN but it is better to have one device instead of two.

i'm trying to setup a local DNS server to manage small office local-only domain names for our servers. i have the DNS working properly (resolving local machines and using the ISP dns if it can't). so i put the DNS server ip into the "Static DNS 1" field of the router settings. the other 2 static dns fields are empty.the problem is that the router is still using the ISP dns server as the primary and my local dns server as the secondary. i verify this in two places. first, if i go to the "status" tab, DNS 1 shows the ISP server while DNS 2 shows my local DNS server. secondly, if i connect to the wireless device with a linux-based machine, the /etc/resolv.conf file shows the nameserver ips in the same incorrect order.
