If you remove the VLAN tags then how would your switch (or any other=20 network device) know where/whom the packets belonging to?!? There "must" be an untagged VLAN in your network... So every untagged=20 packet will go that way... Every tagged packet will go to its own netwo= rk... You signal with the VLAN tag that you want to sent a packet to a networ= k... But maybe I am wrong... :D Swifty
