4.3. PORT BASED NAT
Port Mode allows the user to encapsulate all incoming LAN traffic on a given physical port, on a port-by-
port basis. There is no multicast or VLAN Tag filtering – All traffic on that physical LAN port is
encapsulated out to the WAN, and de-encapsulated in the reverse direction. This mode provides a
Bandwidth Capping feature such that network operators can ensure that links do not over-subscribe their
contribution limits to a WAN.
