Small office simulation router setup

[phonetech1]

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.

Current configuration:

!

service timestamps log uptime

no service password-encryption

!

hostname R2611-1

!

!

ip subnet-zero

ip dhcp excluded-address 192.168.1.1 192.168.1.9

ip dhcp pool 192.168.1

default-router 192.168.1.1

!

interface Ethernet0/0

no ip directed-broadcast

no ip mroute-cache

no mop enabled

!

interface Ethernet0/1

ip address 192.168.1.1 255.255.255.0

no ip directed-broadcast

no ip mroute-cache

!

ip classless

ip route 0.0.0.0 0.0.0.0 172.26.230.1

ip http server

!

!

no scheduler allocate

 

[unclerico]

looks to me like the 3550 is missing a route for the 192.168.1/24 network

 

[phonetech1]

3550 only does intervlan routing. How do I add this route to the existing configuration?
192.168.1 network is supposed to be sort of external to the main network.

on the 3550 add ip route 192.168.1.0 255.255.255.0 172.26.230.150

Thanks, but that didn't work. Someone suggested that I need to setup NAT on the router.
I'll work on this today.

Walk me through your steps now; what device are you trying to ping from/to. As for NAT, there is no need for it in this config. Your 2611 is running some really old code so just for giggles add ip routing to it.

I added NAT and it works. This is exactly what I need. My next step was to add NAT anyway.
Thanks for your help.

interesting. can you post your finished config?? with your addressing scheme and topology NAT shouldn't have been needed to establish end-to-end connectivity so i am interested to see your final configs.
