T2000 - nice kit :)

When you say you bring the interface up with "ifconfig" what exactly are
you entering?

Once the interface is up, what do your routing tables look like (netstat
- -rn)?  Do you have a default route set (man route)?  I've found Linux
wont define a default route for interfaces you define manually with
"ifconfig"; it will only route to the same network the interface is on
(assuming you specified the correct "netmask" to ifconfig).

The next port of call is the arp table - did you try flushing it after
taking the interface up and down (man arp)?  Maybe you're being hit with
a stale/corrupt arp table.

Just some random thoughts :)

HTH,

James
