Question about integration between different sites

[haytham elsamadony]

Hi Guys

I have a scenario want to discuss  about it with you

i have a hop and spoke network ...... one main site  and 4 branches 

each one of them is already an individual company has own network

i want to make integration for some services between them

main server for this service at main site and other branches must connect to this server ...... and each brache has own server who will connect to the main server

i have mpls connection between them

the problem that .... there are overlapping at  ip subnets between them ...... the main site and some branches use same subnet

how i can solve it ??

Hello,

You can NAT their source addresses on your edge router. You need to NAT their destinations as well because if you do not do that, packets do not leave the branches.

No, i can`t use NAT

because, the  server at each site will connect with main server  make syn with it

so, i need to use the actual ip add of  server as it`s to make syn
