LAN to LAN Traffic
The LAN SMTP server replies to the UAG’s LAN IP address and the UAG changes the source address
to 1.1.1.1 before sending it to the LAN user. The return traffic’s source matches the original
destination address (1.1.1.1). If the SMTP server replied directly to the LAN user without the traffic
going through NAT, the source would not match the original destination address which would cause
the LAN user’s computer to shut down the session.
