Cisco IOS & PIX routing through same interface

[JackoReturns]

I have a LAN on 10.10.10.x/24 network with all the clients using the PIX as a default gateway (10.10.10.253)

I have added a Cisco 2651 router to perform VPN terminations between remote offices. The external interface has an Internet IP address, whilst the other interface has 10.10.10.1. All the remote sites can VPN correctly but can only connect to the inside interface of the 2651 router. If I add a static route on the servers pointing back to the remote office LAN IP addresses then all is resolved.

I understand that this is due to the PIX not allowing routing through the same interface as it came in.

How should I configure my router to route the return packets correctly?

can you list the result of

sh ip route

on the PIX.

Thanks.

On the Pix: sh route.

I'd consider making the 2651 the default router, and point its default to the Pix. It'll send icmp redirects to the workstations, and can relay traffic (unlike the Pix).

I've made the 2651XM the default router and is now working correctly.

Thanks for your advice
