I am a newbie to these forums so I need a little help. I am looking for some firmware for the linksys wrt54gs wireless router. I am looking for a specific feature. I am trying have it where it disables all wired connections to the router except the port that says internet. We currently have a dsl connection going from a netopia dsl modem to the linksys router. I am trying to make it so the users can not plug the wired connections into this router. Alternatively I could get firmware that does mac filtering on wired and wireless connections. If anyone knows of firmware that does this let me know.
