I have the two sites RTR1 and RTR2 acting as FW with site2site VPN. On RTR1 I have a static NAT for the exchange server.
From RTR2 site, I can connect on port 25 to the RTR1 exchange nated IP (Public IP) but not on the Private IP.
If I remove the one to one NAT entry for the exchange server, i can connect on port 25 on the private IP. How do i get both to work, connect to the exchange server on private and public IP on port 25?
