NO Thats not correct
Nat Overlapping is ment for such instances. Its true that U need a DNS to
resolve.

NAT won't work because the destination address on each unix host is on the
same subnet as the source address. The Router will never NAT or Route the
packet.

Look CCO for examples on NAt overlapping. Its probably the easier way of
doing the same .

Subject: GRE Tunneling & Bridging
Is it possible to connect 2 locations via the Internet and have both
locations share the same subnet ?
I know that this is theoretically possible by using a GRE Tunnel between the
2 routers at each location AND by
activating IRB on the routers.
(Each router will have a minimum of 3 interfaces - subnet, dmz, & Tunnel;
subnet & dmz interfaces
will route IP - subnet & Tunnel will bridge IP).
Can this work in the real world and has anybody done this before ?
The reason the 2 locations need have the same subnet is that Unix Hosts at
each location need to be configured
in a cluster group on the same subnet for disaster recovery purposes.
Thanks,
Simcha
