Simulating small branch office in lab network

Hi,

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).

Here is my design:

Vlan 230 (the internet)

A port on 3550 is in vlan 230 and is connected to e0/0 (172.26.230.150) on 2611 router.

e0/1 interface on a 2611 is (192.168.1.1).

A PC is connected to e0/1 (192.168.1.12).

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)

Below is my configuration

Thanks for your help.

R2611-1#sh run

You are not performing nat on the router.

This is typically required on a box which provides internet connectivity.

Probably the other hosts on vlan 230 have no route back to the pc on 192.168.1.1

Configuring nat on the router will resolve this problem.
