Select the desired port as the VPN Up-link port. It's required to set the port connected to the
operators' backbone networks to be up-link port.
Note:
If VPN mode is enabled, please create VLAN Mapping entries on the VLAN Mapping function
page.

6.7.2 VLAN Mapping

VLAN Mapping function allows the VLAN TAG of the packets to be replaced with the new VLAN
TAG according to the VLAN Mapping entries. And these packets can be forwarded in the new
VLAN. If VLAN VPN function is enabled, a received packet already carrying a VLAN tag will be
tagged basing on the VLAN Mapping entries and becomes a double-tagged packet to be
forwarded in the new VLAN.
