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

end

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.
