ASA Site-to-Site VPN to SonicWall Overlapping Networks

[wcotis60]

Need to setup a VPN from my ASA 5510 to remote SonicWall TZ170 with overlapping networks, both are 192.168.1.0/24.

One server on my end, 192.168.1.76, needs to receive data from their end PC which is 192.168.1.105.

I understand NAT will be needed on both ends, they are willing to do so.

Simple diagram:

My Server            My Outside                                  Remote Outside        Remote PC

192.168.1.76 ----- 76.7.102.254 <-----> Internet <-----> 66.122.221.254 ----- 192.168.1.105       

I would like to use 172.6.1.76 as the NATted address on my side.

for ASA version 8.2 and earlier:

access-list nat-to-sonicwall permit ip host 192.168.1.76 host

static (inside,outside) 172.16.1.76 access-list nat-to-sonicwall

i assume that there is typo in your address: instead of 172.6.1.76, i assume it's 172.16.1.76?

and sonicwall should also NAT their address to a unique adress.

Crypto ACL should be from the NATed address to the sonicwall NATed address

Hope that helps.
