Hi.

We have a requirement to setup an IPSEC VPN using 2 ASA 5520s between 2 of our sites.


The problem we have is that both sites use the same private IP range; 10.101.1.0 / 24.


Is there a way using (possibly using NAT_ to enable this to work?


SITE A:

LAN 10.101.1.0 / 24

PEER 33.33.33.33


SITE B:

LAN 10.101.1.0 / 24

PEER 44.44.44.44


Help!

that example doesn't quite fit.


what i want is both sides of the VPN to act as if they are within the same broadcast domain?


in a similar way that OpenVPN bridges 2 subnets with its TAP interfaces.


is there a way to do this with Cisco kit?


both ends of the VPN have the same subnet
