View 1 Replies View Relatedi have one SF300-24p switch where i setup some Vlans and echolife hg8245 ONT router to access internet. the diagram is the following
VLAN1 (Subnet of users) -----> Switch SF300-24p
VLAN2 (Subnet of users) -----> Switch SF300-24p
VLAN3 (HG8245) -----> Switch SF300-24p
VLAN4 (Servers) -----> Switch SF300-24p
i want to control access to internet on VLAN1 and VLAN2 (access on VLAN3), while providing access to VLAN4.My problem is in connecting to internet, i can't find a way to "route back traffic to VLANs 1 and 2 since HG8245 don't seem to provide proper static routing ON LAN interface. Maybe without resorting to changing the HG8245 router ?
We have cisco 3550 switch i have configured 3 vlans in this switch vlans are not able to accessing internet
View 7 Replies View RelatedI am trying to setup VLAN's in the company I work for and I am almost there but missing the part when the internet works.I have an SG300 as a L3 Router IP 192.168.0.93.I have created VLAN20 and VLAN40 Assigned VLAN20 192.168.2.1 and VLAN40 192.168.4.1
The static routes have been created and a default router going to the Sonicwall firewall at 192.168.0.1.Port 24 is configured as Untagged VLAN1, Untagged VLAN20 and VLAN40 in trunk mode and going to the Sonicwall NSA 2400. [code]
Working to move all 192.168.0.x network off of VLAN1 and move it a management switch.I have DHCP helper on pointing to the DHCP server.Both VLAN's once the DHCP server is configured to Gateway 192.168.0.93 can get an IP from the correct subnet either 192.168.2.x or 192.168.4.x
All PC's are getting a GW IP of 192.168.2.1 pr 192.168.4.1.All test PC's on both VLAN's can ping each other and any server with the correct GW.When I try to ping google.com or open a web page and try google.com it times out.
Here is what I have. Windows Domain Controller running DHCP with configured scopes.I have one ASA5510 And 4 HP Procurve switches with VLANS preconfigure from vender.
Here are my DHCP scopes/VLANS:
VLAN1 -Default 10.2.x.x/17
VLAN201 -DHCP 10.2.201.x/24
VLAN202 - WLAN EMP 10.2.202.x/24
VLAN203 - WLAN Guest 10.2.203.x/24
VLAN 252 - MGMT 10.2.254.x/24
Here is how I configured the DHCP Scopes:
Changes needed to make to the DHCP Server (AUSPDC) in order to get things working with the new switches.
1) Configure 3 new DHCP scopes on your DHCP server.
a) scope for 10.2.201.x/24 to serve LAN employees and give them a gateway address of 10.2.201.254.
b) a scope for 10.2.202.x/24 to serve WLAN employees and give them a gateway address of 10.2.202.254.
c) a scope for 10.2.203.x/24 to serve WLAN Guests and give them a gateway address of 10.2.203.254.
I just upgraded and decided to go with the VLAN configuration. None of my VLANS can get out to the internet or each other due to I think My ignorance in configuring the firewall.The PC's are getting proper IP address but they cannot get out or to the other VLANs. I tried to duplicate what is working for VLAN1 but it is not working.
Here is my config.

They have a locked Cisco Router which is from the ISP and its confed on a fa 0/0 interface to share Internet access on the network. The ip on that interface is 195.198.11.217 255.255.255.252 and i tried it with a PC (set my personal ip to .218 and entered their dns info (195.67.199.27) and it is working. The question is now. My friend found a 3550 laying around and since the ISP wont let them conf their router he wants to use the 3550 to create 2 vlans with internet access and without access to eachother. Vlan 10 for the desktops and Vlan 20 for the wireless (Moving on to some netgear wireless switches) How would you configure the 3550 for this to work?
View 23 Replies View Relatedi am trying to set up a cisco 2950 with a vlan to seperate all of the pos machines on the network (4 of them) from all other machnes in the building (3 hard wired and wi-fi). i was going to use vlan 1 as a trunk to allow internet access to go from fa0/1 to both vlans (vlan 10 and vlan 20). i have read things about the acl having an explicit deny at the end, so i'm thinking that is my problem. i am testing it at my house before deploying it to the network. i have 1 laptop setup with an ip of 192.168.0.50, and the other is .60. my router is 192.168.0.1. i have the ethernet from the router plugged into fa0/1, the 1st laptop on fa0/2 and the other at fa0/3. before i set the vlans up, i checked the communication by just plugging them in and trying to ping, they could both ping each other, the router and 8.8.8.8. when i finished setting up the test vlans, they could not ping each other(what i wanted) and laptop 1 can ping the router, and 8.8.8.8. laptop 2 cannot ping anything.
the only thing i did was create vlan 10 and 20, set port fa0/2 to vlan 10 and no sh, fa03 to vlan 20 and no sh, fa0/1 to vlan 1 and no sh. then i did switchport mode trunk on fa0/1, and switchport native vlan 1. this seems to be how i was supposed to do it, but it's been a while since i have worked with switches. i'm sure it's simple, but after searching the internet and poring over my cisco books for 5 hours, it is turning out not to be the case. here are some details:

I have a small cisco switch cluster (seven different 2924, 3524cisco switches) with 3550 as a cluster control which does all the inter vlan routing that works fine.
This cluster is in semi production PBX interop testing lab. This is a closed network without internet access and not connected to our corporate network.However now I have to add this capability so some equipment in the lab can get Microsoft updates over the internet.
I've created a port on a 3550 (fa0/19) and connected it to another network that has internet access. It picked an ip address and when I'm logged in to the 3550 I can ping hosts on the outside network. However I can't ping any hosts on that network from any hosts that are connected to my vlans.I've tried a few different things, but still can't make it to work.
Here is a short version of my 3550 configuration:

View 6 Replies View RelatedWe need to give differentiated internet access to three VLANs. Each one of this VLANs is used for totally different purposes, so traffic between the VLANs is not allowed. Each VLAN has its own internet access provided for the data center using one fast ethernet connection.
We're thinking about using cisco 2911 for Internet access, VPN and firewall. I suppose that best option for VLANs is using Catalyst 2960S or a swithing module for the 2911, but these two options are too expensive for us. We're thinking about using swtiches from the SB series (maybe a SG-200).
We're totaly newbies to VLANs so we have many doubts. This are our questions:
1) The 2911 has three on board ethernet interfaces; we have three VLANs and three internet connections, so we need to use HWICs to get three more ethernet ports. That's right?
2) We need three HWICs or there is some kind of HWIC with more that one ethernet interface?
3) The routing solution is to assign static routes in the 2911 for each interface connected to a VLAN through a 2911's interface connected to internet?
4) Simply connecting three different router interfaces with three different switch ports, each one of them assigned to one of the three different VLAN, are we going to get internet access for all devices in those VLANs? or do we need to configure something else like trunking, VSIs...?
5) Can we achieve our goals using the SG-200 switch?
6) We have the chance to use older routers, is this possible? We're specially interested in knowing if a 1841 or a 2801 router could be used for this setup.
7) This is not a production environment so we can use refurbished equipment.
I have a Cisco C3560CG which is running C3560c405ex-UNIVERSALK9-M), Version 12.2(55)EX2.The switch has vlan 1 and vlan 50 configured, vlan 50 should have access to a limited number of host in vlan 1.The following acl has been applied on the inbound to vlan 50:
10 permit tcp 10.16.30.0 0.0.0.255 host 192.168.15.243 eq 137 138 139 445

I sure the above would work, but for some reason some of the packet counter are not incrementing but the traffic is being blocked. But I would like to see the counter increment.Also I have that I may beed to use VACL wouls this be the case?
I've just set up DHCP Snooping and IP Source Guard on our SG500 series switches. It seems to work quite well, except when a wireless host roams from one AP to another (on a different switch port), all traffic from that host gets blocked.
I can understand why this is occuring, but I don't know what I can do to work around this problem.had success with roaming WiFi machines in conjunction with IP Source Guard?
My problem is that I have a Cisco 300 series small business switch with multiple VLANS each one with an IP address and two or three ports assigned to each VLAN. I have an E3200 wireless router that I want to use to use to share internet on the switch. All of the VLANs are reachable from the other VLANs and I've put a static route on the E3200 so that I can reach the VLANs from a machine connected only to the router. But I can't reach machines on the otherside of the router or get to the internet from the switch.

ASA5520 IP (Default gateway): 192.168.1.1Switchport Gi1/0/1 is configured as a routed port, IP address 192.168.1.3 255.255.255.0Example VLAN is VLAN 100, IP address 192.168.100.1 255.255.252.0 From the switch CLI, I can ping all VLAN addresses, as well as the ASA5520, and the client laptop I'm testing with from VLAN 100.
From the client laptop on VLAN 100, I can ping all switch interface and VLAN addresses (inter-VLAN routing is working), including 192.168.1.3, but I CANNOT ping the default gateway at 192.168.1.1.

I have a cisco 2851 router as the edge router, I have a 3750G and a 3560G switch and configured intervlan routing with four vlans, also connected to the switches a four servers and one has active directory and a dns server.i am able to ping from all te servers fine from different vlans and the servers are able to ping the edge router. the problem I am having is with DNS, in the edge router i have configured the isp's dns server address in ip name-server and i am able to reach the outside world.
the problem im having is the servers are not able to reach the outside, do i need to do something in the edge router to forward it to the 3750g or do i have to add my isp's dns servers on the 3750g with ip name-server.
I have this strange problem with my Macbook pro, when I connect it to my cisco 2940 8 port switch then I can reach my ISP (websites eg. google.com) in like 2 minuttes, then something is happening on my router, because suddenly I can´t reach my ISP
This is what I have found out so far:
1. when I lose connection to my ISP then I can only ping internal ip addresses eg. another computer in my network
2. if I renew my ip address on the Macbook then it works again in 2 minutts, then the same happens again. This is my network setup:
Router -> Switch 1 -> Switch 2
I also know that it is not the Macbook, because it have got a new motherboard, and it have been reinstalled
also if I use the Macbook on a other network then it works fine.
All my other computers ( windows and linux ) works fine, no problems.
To me it looks like it is a Nat and/or DNS problem, but I can´t fine out what it is.
We have recently started as Internet service provider in an open metropolitan.
We use a Cisco 3560G Layer 3 switch, where we have all our vlan where we have konfiguerat ex. Switch (config) # interface vlan 150, an interface for each VLAN capabilities such as int vlan 1 - 10/10 int vlan 2 to 30/10, int vlan 3 100/10 and so on.
Our int vlan is configured as follows:
dhcp relay information trusted
ip address <x.x.x.x> <x.x.x.x>
ip helper-address <x.x.x.x>
Ports (ex. int Gigabit Ethernet 0/1) are configured as follows:
description Uplink
switchport access vlan x
[Code].....
Now the problem; we have a customer in ex. vlan 3 who needs to access a server provided by another customer in the same vlan (vlan 3), and access to each other in the same vlan is not possible. You can access the server from any other vlan, but when it comes to access to another host in the same vlan, you will not reach it.
We suspect that the energy company has configured with pvlan isolated. If we use the command ip local-proxy-arp on each vlan, it works to reach each other, but it seems that our 3560 becomes overloaded when ip local-proxy-arp is enabled and it streaming and use IP telephony it doesn't work. The response time at ping is longer and the loss of packets increase with ip local-proxy-arp enabled. The other operators in the metropolitan also uses Cisco 3560G so the hardware should be sufficient.
We have also tried to add no split-horizon, but it made no difference. How do we get around this without negative consequences? Probably need something that makes you allow to send out the same interface that it came from, because it works as long as you are in another vlan.
The Cisco 1921 router has two routed adapters. One is GE0/0 which I am using for my WAN interface. It is working properly. The 2nd interface is GE0/1 which is being used as my internal adapter. It is running NAT. When I attempt to reach the internet it fails while checking the exit interface. Here is the report.

upgrading our small office network. We currently have about 75 employees with probably 125 devices on the network. I'd like to create about 10 vlans for the different departments and then configure intervlan routing as needed. Currently we have all unmanaged switches and it's just a huge broadcast storm on the network. We are upgrading our Cisco 800 router to an ASA5505 sec. Plus license. I need some recommendations on switches. Of course, this needs to be done as cheap as possible.... Is there a way to use the ASA to configure all the vlans and intervlan routing and access lists and use a cheaper switch to provide the access layer to hosts?

I am trying to separate the lan traffic, san iscsi traffic, and san management traffic using vlans. The problem is i'm unable to communicate cross vlan with my current config, which I have attached to this post. The only noteworthy things in my conifg is that the ip route 0.0.0.0 0.0.0.0 192.168.83.6 is referring to a switch stack they have on site, that I will connect this stack to using the first two trunk ports on each switch, that I do not have here in the lab.

View 2 Replies View RelatedI recently set up a Cisco 881 to cover a small business network. The router is currently set up and working as expected. We recently decided to move to VoIP phones and here is where I'm running into some issues.
First an overview: We run a network with a cable internet WAN connection, this connection is DHCP, however we have a static IP through our ISP. We also have a block of 30 additional IP addresses for one to one mapping as we need them. The new VoIP system is being run over T1 lines throughout the township (we are a municipal organization) and the VoIP system is being run to about 5 buildings in the township.
This brings me to the topic of VLANs. As the phone engineer explained it to me, there is a network set up over the T1 that allows the VoIP equipment to talk to one another and operates all of the VoIP phones on one network. The equipment that is being installed at our building connects to the network over the T1 and "talks" to the other equipment on the network. The engineer wants to create a VLAN and run it on ports fa1 and fa2, with the fa2 port being connected to the actual "MPLS" (their term) that connects to the T1 and into the cloud, and the fa1 port connected to the internal phone switch.
TLDR; The problem is this: When we attempt to set up the VLAN on ports fa1 and fa2, we have no connectivity with the other units in the external VoIP cloud. Pinging while directly connected to the "MPLS" yields successful pings, while pinging from the router with the "MPLS" connected to fa2 yields failures. I'm going to post the running config below, I feel like what we're doing should be working. I asked around about subinterfacing, but others seemed to think this was not necessary.

Using the 4th Edition Self-Study Guide from Froom, Subraniaman, and Frahim.In Ch-4 it talks about End-to-End VLANs and Local VLANs. I read that section 4 or 5 times and still did not understand the difference between them two.I know one spans across the entire network and the other is local. What do they exactly mean by that?
