Routers / Switches :: How To Connect 3 Outside Connections And Route Them Properly
Jul 19, 2012
We are planning 3 Internet Connections into our building. 1 will be for actual Internet traffic, 2nd for Voip phone system, and 3rd for internal network for Active Directory...etc. Oh the AD servers are controlled by another business so technically this line is still considered and outside line and is a T1. What I need to know is how best to make this all work so that our internet phones use the VOIP system, computers can log into the domain and access that network but use the Internet network for actual internet traffic? We were considering a series of managed switches and creating 3 VLAN's but I'm thinking we instead need a new router that all 3 networks connect to and dishes out DHCP to computers and phonesn example network is below.192.168.1.x ----> Internet (all computers use for internet traffic)72.10.10.x ----> VOIP (All physical and software phones use this network)10.10.10.x -----> Connection to external company that controls our network and has domain controllers, mainframe...etc.

ive been having some issues with my internet, i had an attack on my pc recently by some american orginization, ive reinstalled new windows on my pc, reset my modem, and nothign seems to work, i have too many tunnel adapters in cmd ip config i think, bell canada hooked up my internet lines and they actually joined two or more wires together and strung them up on the neighbours fence and mine and even wrapped it around a tree branch, god knows why they would even do that, maybe they think when the tree grows it will cost me money to fix it and theyll earn from thier mistakes instead of learn from them... anyway this is my ipconfig test results as explained in previous post from someone.Windows IP Configuration[CODE]

I'm not sure about my title, it;'s the best I could come up with. I have approximately 7 computers, two iPhone, and iPad, wireless printers and a network attached storage. Most are connected over via wifi, the exceptions being one pc, the nas and a printer. I plan to add six more devices plus some ip cams. The way the router or network is configured whenever a guest connects to our wifi they can "see" our computers. I haven't been able to tell if they can see the files or just the name of the computer. Question 1: How can I tell if the guests are able to access the data on our computers or networked drive? Question 2: If I add a switch will I need to do anything special with regard to security?

My itty bitty manual just shows on how to hook up my router via cable modem...nothing on how to secure it. I go into setup of the router and see where one can add info but am at a loss what to enter. I tried, merely by guessing, applied the info, and screwed up my networking. I couldn't even get into my router to revert back, cause i couldn't get on line...finally i reset manually my router and all is well again, except when i see a list of nearby network users, mine is the only one that says unsecured.

Does the Host file allow connections to your computer?Although I have placed some server names into the host file, Wallwatcher 5.0 is indicating that those servers have made connections. This didn't seem to be a problem before I took some online advice to add servers to my host file. I use iptables on a WNDR3700 router with DD-WRT firmware. In the iptable rules I've also blocked these servers. One example is cnbc7.net and a couple of U.S. Akamai servers.

Had laptop connecting wirelessly perfect with no problems. We then added another laptop and PSP 3 to the house hold. Any of the 3 devices will connect to the internet via wireless but ONLY one at a time. If you are connected with one and turn on one of the others it will kick the one off that you were on and only 1 device can use wireless at a time?

Virgin media superhub was swapped for a new identical one as some users were unable to connect, but my connection was fine. When i booted my system up after it was configured by virgin I could see all connections but clicking on any "connect" button doesn't yield any form of output from the computer. Password problem? I dont get a response whenever I click "connect" on any of the other 20 wireless connections that i'm picking up, none of them being mine. When trying to add a new network from "network and sharing centre" via "set up a new connection or network" button on the mainpage or "add" button on the "manage wireless networks" tab yields the same, absolutely no reaction from the system.Now, I only add this info for science of deduction purposes, because it is truly baffling me right now, but when i first discovered the problem and went into "devices and printers" in contr panel and "add a device" my computer paused and then BSOD'd.
Things I have tried:
Updated the network card drivers Ran start up recovery - no problems detected after 20x running Logged onto the superhub through another users system and added my mac address to allowed lists, reserved i.p. address - both on and off, all combinations Pressed the wireless card button on the back of my system on and off, repeatedly Disabled/enabled network adapters in device manager Run winsock and dns flushes, ip release and renewals (e.g. things like "netsh int ip reset; netsh winsock reset; ipconfig release;renew)
Each and every troubleshooter All the usual power issues, from setting maximum performance on the network card to unplugging and socketing the router main repeatedly Administrative tools-services-dhcp client-start&auto Tcp/IP protocols-ip and dns configured automatically?
*Haven't tried (last resorts)* Reinstall windows Remove, inspect and possibly replace or just refit network card and factory reset
Give Richard Branson a slap Observations/Details Everyone, EVERYONE else can connect to the network, no problem I have full strength signal to the connection I know the password and it certainly hasnt changed All we did was swap identical routers! Logged into my other windows on a partition (original user account, messy so partitioned and made a clean install, but this was long ago and no network issues ever existed) and have the old exclamation mark over signal bars - troubleshooting it causes nothing, but at least the adding network functions yields results and it says im technically connected to the router - ive tried all noted fixes above on this windows install also.

I have the setup as following on my PC:
[code]...
I use the fibre internet for almost all internet activities since the speed is fast.However, when I do school's stuff, I need to VNC to my lab's server. Hence I need to connect to school internet point. External IP cannot directly connects to my school's server.Therefore, I would need to force Windows (or VNC) to use the connection of the Wireless Ethernet card when I VNC to my lab's server. But I want to use my fibre for all other internet activities.

I have a Cisco 2851 (with a 4 port switch module) that I am trying to set up with two different internet connections, and have it route traffic out to them based on the source IP. One connection is a 50mb Comcast connection, another is our T1 that our servers are hosted on. The goal is to guide server/phone system traffic to the T1 and have the rest default to the Comcast. I currently have the 2851 connected to our Layer 3 switch (Dell Powerconnect 6224) with a subnet created between them. Static routes have been created on the 2851 back to all of our existing subnets. Traffic flows internally without a problem between the subnets and 2851 (and vice versa). I set up the 2851 with route-map's in the NAT to control the flow of traffic, with the default route set to the Comcast connection. Default route works great, speedtest shows full speeds and everything looks great. The problem happens when I apply my route-map policy to the internal LAN interface with the ACL list of IP's that I want to guide to the T1 (with a next-hop of the T1's IP address). I tested some tracert's and pings from one of the IP's in this list and they would stop at the T1 modem and not go any further. I did a "show ip nat translations" and noticed that the "outside" portion (right half) was blank for every IP that was in the ACL or related to the T1. So my guess is it looks like this is not doing NAT for the T1? I double-checked that I had my "ip nat inside" on the LAN interface and "ip nat ouside" on the T1 VLAN interface and Comcast interface and they were there.

How to configure my DIR-615 (Hardware Version E1 - Firmware Version 5.00NA) to:
1. Assign/Reserve IP address for 2 machines.
2. Route a web browser to a server on the first machine (port 80) as a default when another computer or smart-phone or device joins my open wireless network.
I am hoping to eliminate any changes to the IP address of the first two computers so that the server's IP address and port are static. I would also like anyone who joins the network to merely open their browser and be presented with the http interface from my server.

Went to log into the web admin interface on my SG-300 today and I get this in both IE and Firefox:
I'm not able to login by typing user/password and just pressing enter. I've tried power-cycling the switch, however, since the power cycle, the font-panel system LED has been blinking green. I seem to recall, though I can't locate the reference now, that this means the switch is running with factory settings, but that cannot be right because:
1. I had previously saved a new configuration on the switch, which it should be using now.
2. It is answering on the configured non-factory IP address -- just not rendering the web admin interface successfully.
I've had this unit for approximately a month. This is not the first issue I have had with this unit (see: [URL] and I'm experiencing some strange LAN speed issues since I installed it. Do I need to RMA this thing?

Is this known bug that you cannot backup (export) full running or startup config from this switch? Will this be fixed in next firmware? (btw, still no new firmware with CDP support for this script altough sales literature mentions that it should have already been available...)Switch does let you backup configuration as text file (which looks similar to normal IOS config syntax), but it doesn't contain all settings so the file is pretty much useless to restoring the config to another switch.At least following settings are missing from the file:
- management interface config (including DNS settings)
- passwords
- remote syslog server config
- SNTP server config
- IGMP config
- LLDP config

I am having some issues with getting DHCP Relay to fuction properly over our SG300-20 Switch.Out current layout is as follows. Hanging off the SG300-20 are a pair of Clustered Checkpoint Gateways with VLAN'ed interfaces in Both of our 2 VLANs, a 3COM 4200G In VLAN1 which has the DHCP server (And all the other Servers) connected to it, and a Pair of HP Procurve 2520's Stacked in VLAN 2 to provide PoE for our Phones/connectivity for our PCs.The problem is I cannot get the DHCP Relay to fuction from VLAN 1 to VLAN 2. If I assign an address in VLAN 2 manually to a device connected to the Procurves, everything works fine. I am able to reach both VLAN 1 and VLAN 2, but DHCP aquisition fails even if the device is connected directly to a port assigned to VLAN 2 on the SG300. The SG300 is running at Layer 3 currently also.
Here is a copy of the running config:

At our office we use seven Cisco 300 Series Small Business Switches. One main switch in the server room and one in each room. They work great! But I’m having difficulties getting the Auto Voice VLAN to work correctly. In fact, it seems to works straight away on a PoE model, but not on the non-PoE models.
Switch (main server room):
Cisco SG 300-28 (PID:SRW2024-K9)-VSD
Switches (one in each room):
Cisco SG 300-10 (PID:SRW2008-K9)-VSDCisco SG 300-10 (PID:SRW2008-K9)-VSDCisco SG 300-10 (PID:SRW2008-K9)-VSDCisco SG 300-10 (PID:SRW2008-K9)-VSDCisco SG 300-10 (PID:SRW2008-K9)-VSDCisco SG 300-10P (PID:SRW2008P-K9)-VSD
All these switches use firmware v1.1.1.8. The switches in each room are connected to the central switch by Link Aggregation. The main switch is configured in Layer 3 mode and all the others in Layer 2 mode. We have a lot of VLAN’s configured. For this problem allow me to describe only the two that are relevant.
VLAN 102 - Internal Network (Clients)VLAN 104 - Internal Network (Voice) The switches on each room are mainly used for clients, printers and IP phones. The clients and printers should operate in VLAN 102. The IP phones should operate in VLAN 104. For this to work I have the 10 port switches configured as following.
GE1 – Trunk – 102U;104TGE2 – Trunk – 102U;104TGE3 – Trunk – 102U;104TGE4 – Trunk – 102U;104TGE5 – Trunk – 102U;104TGE6 – Trunk – 102U;104TGE7 – Trunk – 102U;104TGE8 – Trunk – 102U;104TGE9 – Trunk – 1P (LAG 1, with 1U;102T;104T)GE10 – Trunk – 1P (LAG 1, with 1U;102T;104T)
The network is fully routable. A DHCP Server is available. Each VLAN uses DHCP relaying. If we statically assign a VLAN to a port, that just works fine. Auto Voice VLAN is enabled with VLAN ID 104. All switches are configured the same. But this is what occurs…
When I connect an IP phone on the SG300-10P the IP phones are assigned to the Voice VLAN ID 104. If I would connect a desktop to that same port it is assigned to VLAN ID 102. Exactly as it should.But when I connect an IP phone on a SG300-10 the IP it is assigned to VLAN ID 102. But I also noticed that in some cases they are assigned to VLAN ID 1 and don’t get an IP Address. That depends in which order I change settings. The port its VLAN membership is then even changed to 1P. Although the port is recognized as an “IP Phone” by the smartport feature. I have noticed it does make difference if I modify the smartport macro and change the native_vlan paramater from "1" to "let's" say "102". That seems to affect it. Of course it may be just coincidence. What am I doing wrong? How should it work?How should you actually configure each port on a switch? (trunk?, Tagged/Untagged VLAN?)If you do not use Telephony OUI. Do you still need to configure the macros on the smartport defenitions?
I have tried about everything. I have also tried Telephony OUI, but it doesn't make any difference. I just can't get it to work properly on the non-PoE switch.

How do i connect two internet routers to one IP address range?I currently have one broadband router connected on 172.16.0.3 subnet 255.255.0.0, I have a second line which is a copper ethernet EFM 2Mb line connected using a Cisco 1800 router configured on 172.16.0.254 subnet 255.255.255.0, no DHCP is configured on either router. the dhcp is provided by a windows 2003 server on our LAN which is also configured on the same LAN IP range. if i connect the Cisco router into the same switch as the broadband router my network devices stop working and dont respond.
If i check the broadband router it shows all the connections to it as having the same MAC address as the Cisco router?? if i disconnect the Cisco router everything returns back to normal and works perfectly.What I want to achieve is to be able to run both routers on the same LAN to provide internet access by configuring the pc's to route through a specific router. the DHCP I want to stay routed through my original broadband line. at the same time i want all pc's to access to the lan devices (ie. servers and printers) what the correct configuration would be for the two internet routers would be?

I've tried some configurations i found online, but can't get to make the network functioning. The routers and powerline av are all dlink. I don't mind having 2 networks, but it would be better to have only one

How to properly power down the Nexus 5000 and the fabric interconnect switches? I have looked up and down cisco's and google web for steps, but they are all coming back with the answer to just disconnect the power cables after you have power down all the windows os and exs servers. Before i do that, I just wanted to make sure that that's the correct way to do it or if there are actual commands that I will need to run on the devices to properly power down. I know that the FI do have a command to reboot, but i need them to completely be power down.

I have a bit of an unusual networking situation here in my home and need proper configuration, so I stop losing my web connection on a daily basis.The reason I'm forced to have the 2nd router is that my wife telecommutes and the 1st (primary router) is provided by her company. For whatever reasons, her company will not allow the wireless radio in their router to be turned ON - which forces me to add the 2nd wireless router for our 3 computers that require wireless access.
1 - Since the primary router has DHCP enabled, I am assuming that I should Disable DHCP on my wireless router. Am I correct?
2 - What other settings on the wireless router do I need to pay particular attention to in this situation?

I recently moved out of state and have been working remotely. I just got a new internet provider who will not let me connect to my office VPN without a small business account which is ridiculous. I've been reading up on how to work around this and haven't been able to figure anything out. I've signed up for a dynDNS account but the truth is I have zero experience with this and don't know what I'm doing - most of the stuff I'm reading is a foreign language to me. I can log into my router and change settings and I can get VPN info from my tech person and work so I just need to know what to do. I can't really work effectively without access to my network but I refuse to pay for a small business account
