Site-Site VPN between Overlapping Networks

Hi,

Pls go through the scenario :


                 Home
                      |
ASA 1 ---- Interent ------ASA2
  |                                            |
192.168.1.0/24                192.168.1.0/24
   |
192.168.1.10/24

from the scenario :

U might have understood that we need a Site-Site VPN tunnel between Same Networks.
i.e 192.168.1.0/24 to 192.168.1.10 server but the server is public NATTed as well with
115.11.226.X.


I have gone through few cisco doc's and found the configuration for POLICY-NAT.

When i di Policy -NAT as the server is Static-Natted , it has taken precedence.

What is the solution on such conditions?

Regards
ramk

you should NAT the source on ASA2 for site to site vpn traffic (let's say NAT to 192.168.100.0/24) and create an exempt NAT on ASA1 for traffic 192.168.1.0-10 to 192.168.100.0/24. The exempt NAT rule have a higher priority than static NAT

In that case what would be the ACL on ASA2 because you are not natting ASA-1 end
traffic i.e 192.168.1.0 ,

As per your configuration above , ASA-2 will see 192.168.1.0 Network but ASA-2 Lans also
with 192.168.1.0

Pls advice

Create a secondary address on the server, make sure that only that address shows up in your internal DNS.
