I still didnt get it to work, but ok, here we go. My Test lab is as follows. Why am I using two separate nics you ask? well, because i've tried it with one nic, and no go. (I have one catalyst 5500, and two main networks I need to run from them). Again, any help is greatly appreciated. Firewall, 2.6.11.4, one rtl-8100 and one intel (using e100 driver) the e100 is aliased to adm the rtl-8100 is aliased to int 3/1 on the switch is the int interface on the firewall 3/2 is the adm interface.
