TechInfoDepot:DD-WRT/WAN Port

per phuzi0n:
 * For better performance you should use the VLAN GUI to reassign the WAN port to the same VLAN as the Project:Network/Local area network ports. Using the "assign to Project:Network/Local area network" option bridges it (software) in br0 which is limited by the CPU instead of switching (hardware) which is limited by the switch ASIC's.

When the WRT is used as an Access Point (AP) or repeater (WDS), the WAN port can easily be configured as a normal Project:Network/Local area network port.

Adding WAN Port to Project:Network/Local area network Switch to use as an additional, normal Project:Network/Local area network port
Note: Steps are true for firmwares current as of the author date of this article. v2.4, post SP2 firmwares. These steps were done with build 12307 (2009 06 17), widely regarded as stable. Other firmware builds of DD-WRT have the same or very similar steps.


 * 1) Open up the Web Interface to your DD-WRT Device
 * 2) Set WAN 'Connection Type' to Disabled.
 * 3) Down the Basic Setup page, the option WAN Port appears. Check the box 'Assign WAN Port to Switch'.
 * 4) Save/Reboot

The WAN port is now the same as the other Project:Network/Local area network ports.
