VLAN BASED NAT CONTROL

The VLAN Mode allows VLAN-tagged datagrams from the LAN side to enter a WAN after multicast
encapsulation, similar to the Tunnelling NAT mode. In this mode, however, flows are based on VLAN
Tags, rather than unicasts/multicasts alone. Up to 128 unique flows can be configured per processing
core, with independent encapsulation headers.

Figure 4-11: VLAN Based NAT Mode Block Diagram



Each VLAN flow must have a unique Tag value.  Two or more flows cannot share the
same VLAN Tag because there is no ‘Packet Replication’ in VLAN Mode.

VLAN Mode does not support nested VLAN Tags.  The 7880IPG-NAT only supports
Ether Type=0x8100 traffic.
