Hey folks,
Essentially Vendor A has a tunnel with Customer B (me). However, they really are sending their traffic to partner C through me, and the problem is that Vendor A has a private source IP that is the same as in partner C's network. Partner C refuses to NAT anything, so I need to do it myself.
This has to be common but I cannot figure it out. The tunnels are up. The normal config for tunnels to work is there, but now I need this additional NAT statement and perhaps ACL rule and I am struggling.
Vendor A's private source is 172.16.1.1 and I need to translate it into 10.1.1.1 before it reaches the destination of 192.168.1.1, otherwise it won't come back to my firewall.
The VPN is already up and 172.16.1.1 is allowed to talk to 10.10.10.10 and there is the appropriate ACL and no nat for this. I only want 172.16.1.1 translated to a source of 10.1.1.1 if it is going to 192.168.1.1
