Communication between two remote sites having same subnet

[Haroon321]

We have two remote sites that have servers connecting with them,Both sites are connected through routers (2800,4300) site A subnet is 192.168.10.0/24 and site B subnet is also same 192.168.10.0/24 and site A server Ip is 192.168.10.1/24 and site B server Ip is 192.168.10.2/24. Now we want to  connectivity between them . kindly give us solution.

Hi there,

You will need to configure static NAT on one of the sites.

For example, create a new subnet 192.168.11.0 /24 at SiteB, ensure it is advertised to SiteA and then create static NAT statements for each required SiteB server. A server in SiteA will then connect to the translated address from the 192.168.11.0/24 subnet instead of directly.

cheers,

Seb.

I am very  thankful for your concern.

But actually the problem is that according to client requirement we have to configure same subnet on both site according to your point of view we don't have any option for new subnet.

You can continue with the existing subnets, you just need an additional subnet to NAT the duplicate subnet behind.

There is no other way to do it, as far as SiteA is concerned, the server in SiteB resides in a connected subnet on SiteA.

cheers,

Seb.
