Hello questions,
I've tried getting 2 NICs to work today, and sofar have failed to
get the second one to work. I'd like to be able to ping a device
attached to that second interface, ofcourse.
{DSL-modem} ----- [ FreeBSD-box.ep0 ]
[ FreeBSD-box.xl0 ] ---- [ HUB ]
|
|
[NT Workstation ]
I know it's probably just my config, and I guess I don't quite grasp
yet how the kernel decides what NIC gets a certain packet. Can
someone explain?
Here's the deal:
