[K12OSN] OT - Linux router - I'm stuck <-long

Fri Mar 26 15:00:04 UTC 2004

here is another question:

Does it matter at all which interface is which?
in this instance
eth0 is the buildings network
eth1 is the route to the office
eth2 is the route to the highschool, the internet, and is the default route

would changing things around so eth0 goes to the high school, internet 
and is default make any difference at all?

If none of these work, I'll probably take the 3rd network card out of 
that machine, and setup another one to go to the district office
