Problem: Ever tried to treat some servers in your local IP Subnet exceptional in “non-transparent” Mode? OK, the solution for this  is the function “real servers are local” BUT what to do if your Exchange Server Roles are separated and you need your Mailbox-Servers to work in non-transparent modus?

Solution: In your Kemp Configuration take your Mailbox-Servers into the VS (Virtual Service) and disable them. This will tell Kemp: Hey, I know them and I have to treat them as non-transparent.

Have Fun, Jimmy
