NAT (Network Address Translation)
NAT (RFC 1631) is the translation of the IP address of a host in a packet, for example, the
source address of an outgoing packet, used within one network to a different IP address known
within another network.
The VSG automatically performs NAT on the LAN. You can also set the VSG to perform NAT
on the WAN for VPN (IPSec and PPTP) connections.
