We have to set up a Site2Site VPN with a customer using ISA Server, but our internal IP range is already used on their router for another site-to-site VPN, so they linked our setup to a new range.
What are my options on ISA Server to route the ip-range they are going to use for us to our real internal range?
Customer sends to 10.226.10.x
our internal range is 192.168.10.x
how to make our isa server translate 10.226.10.x to 192.168.10.x.
Or does this mean our only option would be to change our internal range completely?
