We connect to over 100 site to site VPNs at this time. Every one of the remote sites currently has a unique LAN subnet.
So many new clients all have a 192.168.1.0 subnet etc on their side and we cannot figure out a way to allow them to keep those subnets since we already have matching ones on our side in use from remote companies, etc.
There has to be a way to do this with a device that allows 4000 site to site VPNs.
All we can find are ways to NAT in the event our subnet is the same as the remote we are trying to connect to.
