The Bridge function on Vigor165 provides a direct connection between the DSL connection and Ethernet, the connected device (firewall, router or PC) can log into the Internet (your ISP) directly without NAT and have full control over the Internet connection.
Vigor165 provides two Bridge mode options, Bridge mode and Full Bridge mode. We may choose which mode to use according to the DSL line requires VLAN Tag or not.
When the Internet Service Provider requires a VLAN Tag, double VLAN tags or multiple VLAN Tags, use Full Bridge Mode.
When the Internet Service Provider doesn’t require VLAN Tag, use Bridge mode.
