I am having one major problem. I have the Asus P4C800 DX with the built in gigalan from 3Com. Now, when I connect to my router, there is no problems with internet or msn, however things like remote assistance wont work. Also, once I install sygate personal firewall, no matter what I do, it will not connect to web pages or MSN, even though i can ping and trace rt them. Some how the packets are being dropped once they reach the LAN I think. I dont know if it is a incompatibility with the 3Com and certain hardware. The onyl way I can use sygate and the router together is to add the lan into a network bridge, but I shouldnt have to, and even then remote assistance and stuff like that doesnt work, even if I DMZ myself. This is frustrating me. I have another Realtek external nic, and it works without a problem with these. I can not understand why this built in giga lan wont work...
