IPsec and multiple identical P2 subnets

[unsichtbarre]

Hi. I have a need to create IPsec tunnels to several sites, unfortunately some of them have identical networks.

pfSense LAN: 10.0.0.0/24
Site 1 LAN: 10.0.10.0/24
Site 2 LAN: 10.0.10.0/24

Obviously this is not ideal, but I have no control over that. Is there a solution?

THX,
-John

No, it's not possible to route the traffic properly if the remote networks overlap.

You have to either change or translate one. But both of this have to be done on a remote site.
You can ask one of them to nat it for you.
