Route Traffic Through VPN?

[steven.wright]

All,

I have 3 locations at, site A, B & C.

Site all 3 locations are connected to each other via a VPN tunnel. However the link between site A and C has gone down. I would like to route all traffic from site C to site A via site B, is it just a case of putting the following on the config of router C...

ip route <NW A> <SUBMASK A> <INTERNAL ADDRESS OF ROUTER B>

I assume that once this packet is received by router B the destination address is looked at and forwrded to Site A, the source address will change to use the address of Router B. Therefore the VPN between Site A and B will be used for this part of communication. I hope this is clear.....as mud!!

Hi Steven,

assuming you have static routing on all 3 sites, than you have to do a

ip route

on router A also. Because otherwise the new returm path isn't known to router A.

And if "the source address will change to use the address of Router B" doesn't meens your doing NAT for networks A and C on router B, than I'll think you have also to adjust the local and remote settings of the 2 vpn tunnels A - B and B - C.
