cisco 831 and multiple lans?

[VasiliyP]

Hi,

I've run into problem, and I'm new to Cisco thing, so decided to ask you a question.

I have 831 running 12.3 T9 (or something like that). I have WAN connected to Ethernet0, and my LAN (192.168.10.0/24) connected to Ethernet1.

Also, I have another network, connected with point-to-point connection which has IP addresses 192.168.99.0/24. What I need is to allow few systems on 192.168.10.0/24 to talk to 192.168.99.0/24.

How can I do it? Is it possible with 831?

Thanks.

Connected to what?

it's t1 point-to-point, but both ends are ethernet. ie, i see this as just very long ethernet cable.

It was my understanding that e0 was the LAN and e1 was the WAN.

What is at the other end, I.E. router?

192.168.99.0/24---T1---Internet---T1---192.168.10.0/243

If this is your setup, then you would do this in the 831

router>en
router#conf t
router(config)#ip route 192.168.99.0 255.255.255.0 x.x.x.x

x.x.x.x is the ip address of your WAN interface (E1, according to Bill). You should also have

ip route 0.0.0.0 0.0.0.0 x.x.x.x

Right?

Then, you would do this in the other router, if it is a Cisco, Adtran, or Dell/some other manufacturer cheap Cisco knockoff...

router(config)#ip route 192.168.10.0 255.255.255.0 x.x.x.x

Again, x.x.x.x being the ip address of the WAN interface.

Burt,

My config is slightly different.

192.168.10.0 -> Ethernet1 Cisco831 ----> WAN (internet)


192.168.99.5 -> T1 -> rest of .99.0 network

I need to make those two network accessible to 192.168.10.1. Ie connect cable coming out of T1 device (ethernet) in to one of the 3 ports of 831 and setup routing.
