Overlapping networks - NAT

LCMember2683 — Fri, 18 Nov 2011 13:10:55 GMT

Hi!

I have another problem - this time with overlapping networks. Here is a picture:

I'm the administrator of PA1. How can user from PC1 connect with PC2 ? I tried with destination and source nat on PA1 but i had to add routing to the destination translated address on PA1 ? How can I do that without adding this routing ? Is it possible ?

Regards

Is there any reason why you are against the route?

Can I add the same route (192.168.0.0/24) to the two differnet locations ?

you could try setting up host routes on the routers, or use source/destination nat on the PAN

eg.

routes on PAN:

192.168.0.1/32(pc1) next hop 10.0.0.1(rtr)

192.168.0.15/32(pc2) next hop 10.0.1.1(r1)

if you set the similar host routes on your routers, you won't need nat.

on rtr

192.168.0.15/32(pc2) next hop 10.0.0.2(pan)

on r1

192.168.0.1/32(pc1) next hop 10.0.1.2(pan)

If this is not possible you can set up nat like:

source 192.168.0.1(pc1) destination 10.0.0.2 sourcenat 10.0.1.2 destinationnat 192.168.0.15(pc2)

source 192.168.0.15(pc2) destination 10.0.1.2 sourcenat 10.0.0.2 destinationnat 192.168.0.1(pc1)
