HELP - VPN IPSEC - SUBNET OVERLAPPING

EdwinBernal — Sat, 08 Aug 2020 02:03:41 GMT

I require a help
I have to perform a nat in the tunnel, because my network conflicts with that of my other site:
Site 1
192.168.50.0/24
site 2
192.168.50.0/24
Serial connection from site 2 to site 1 to a specific server
192.168.50.0/24 -------- 192.168.50.253 (Server)
I need to do NAT with network 172.50.1.253 at site 1, 192.168.50.253 NAT 172.16.50.253
I have looked for information but I can't understand the scenarios and most of them do NAT in both sites, but in my case I only need to do it in one site.
Could you help me

@EdwinBernal

If subnets are overlapping you need NAT on both sides.

Attaching the document that explains same scenario as you have and how to do step by step.
