Hi I have a Pix506 on site A which is configured with 2 tunnels IPSec to my corporate network.

My net on Site A is 172.26.46.0/24.

On my site B I have a VPN 3000 (tunnel A-B) until now is ok

In site C (another VPN 3000) Tunnel (A-C).

Sites B & C are connected vía WAN eigrp.

I would like that tuneel A-C be a backup for tunnel A-B. The problem is that in sites B and C I have to configured an static route to traffic going to site A but those sites are connected so I can not have the same route in both sites....


How can I do in my Pix a NAt to translate traffic 172.26.46.0 into 172.24.24.0 a reach my site C. In site C I have a route to reach 172.24.24.0.


Any nat suggestion? what I can do?


Thanks

Regards

Hi

but if you are managing site A, B and C lan, why use NAT ? is there overlapping somewhere ?


How is the EIGRP peering made between site B and C ? Using a router in every site ?


If yes I can suggest to build a sort of wan (using a GRE tunnel) via Ipsec VPN with a router behind PIX506 in site A on both sites.


On all the three wan link run EIGRP and everything is dynamic if something fails...


If help pls rate.

Tks
