This question already has an answer here:
What is the best way to deal with this problem.
I have a VPN set up on my firewall that runs from a server on my side to a Customer Site.
It is configured as serverA on my side and 172.31.255.1 /24 on the customers side.
I now have a new customer who also needs a VPN set up. But their IP address clashes with the above range.
So they need to run from serverB on my side to 172.31.255.18 /32 on the customers side.
As you can see, the new one is right in the middle of the range used by the other one.
What is the best / recommended way of working around this problem?
