Routing Problem

[joeschmoes]

I am having a routing issue. I will start by drawing out the way the network is set up.

Router 1
eth0 192.168.1.165
eth1 205.128.1.114

Router 2
eth0 10.1.1.1
eth1 205.128.1.113

Most of my clients are connected through the 192 network.
I have a few server connecting through the 205 network
The 10 network is a VLAN that has printers, wireless access points, VoIP phones, and a few servers.

I'm sure the setup is not right because I don't think I should need 2 interfaces on 2 separate routers with a 205 network address. Currently my 205 network and 192 network are in the default VLAN1.

How would I configure this setup to allow access to all subnets?

I think what is happening is traffic from my 10 network to my 192 network is getting goofed up. When traffic leaves my 10 network workstation/server destined for a192 workstation, it goes to router 10.1.1.1 -> 205.128.1.113, then to 192.168.1.165 -> 192 workstation. But, when the traffic is coming back it goes from 192 Workstation ->192.168.1.165 to 205.128.1.114 ->205.128.1.113, then to 10.1.1.1 to -> 10 workstation/server.

so there is one line going from R1 to R2 via the 205.128.1.x network?

Tell us how the network is physically cabled.

router1 has 2 interfaces. 192 and 205. They are both plugged into a switch.

router2 has 2 interfaces. 10 and 205. They are both plugged ino the same switch.

Some of the servers are plugged into the switch as well. Anything with a 10 ip address, is on VLAN10. Everything else is on the default vlan1.

Please let me know if you need more information.

So R1 and R2 only have 2 interfaces in total and they are both connected to the switch??

Is anything else connected to the routers?

How are users getting out to the Internet?

If the switch is layer 2, and there is nothing else connected to the routers. You should be able to get rid of 1 of the routers and 3 of the links. You should only need 1 link going into the switch. Everything else will be on VLANs. The router would route between the VLANs.

I second eliotb's statement and whoever set that up should be fired.

There is another router for internet. I don't believe it is correct either. The serial interface has a 216 ip to connect to the ISP. The e0 interface also has a 216 ip that connects to a PIX firewall which has 3 interfaces. A 216, a 192, and a 205.

There is also an ISA server which has a 216 as it's outside interface and a 192 as it's inside.

I know this is a big mess. This is one of those types of things that sort of created itself. Now, however, we are noticing very slow traffic and I feel this is the source.
Thank you all for your help and replies.
