Cisco 2611 and Smoothwall Trouble

Unanswered Question

I am currently running Smoothwall and a Cisco 2611 router on my network.

On my Smoothwall, ifconfig -a is:

eth0 - - green

eth1 - - orange

eth2 - xxx.xx.38.35 - red

On my router, show run is:



router rip ver2

ip route (for gateway of last resort)

My smoothwall is using dhcp on all interfaces. I don't think my router is forwarding traffic correctly.

My smoothwall can ping and nothing else past the router.

My router can ping my smoothwall, outside network, internal network...practically, everything.

My internal network can ping and, if and only if I assign each node a static ip because nothing can receive an ip through DHCP.

I'm at my wits end with this. Does anyone have a clue??? I hope I provided all the necessary info. By the way, the orange interface on smoothie has nothing on it as of now.

Does your router Fa0/0 really have the same IP address as your smoothwall eth0?

What device is providing DHCP services? If the smoothwall is, then you will need an ip helper statement on your router's fa0/1 interface pointing to the smoothwall's eth0 ip address.

Something like this:

int fa0/1

ip helper-address

If you need more assistance, then please provide the complete interface configuration for your two fast-ethernet interfaces.

I checked and router FA0/0 is and smoothwall eth0 is

My smoothwall will be providing DHCP services.

I just came across relay agents, but I'm not sure how to do it. I programmed the router with the line that you provided still to no avail.


ip address

duplex auto


ip address

ip helper-address

duplex auto

speed auto

router rip

version 2



ip classless

ip route

ip http server

ip pim bidir-enable

Hope this helps.

Ensure your DHCP server is handing out the correct information. For instance it should be handing out leases for the network, the gateway it hands out should be

I'm not familiar with the Smoothwall, but is there any logging happening there that will help?
