Awesome! Thanks so much. That's exactly what I was looking for. I must
have missed it when I tried to grep the directory looking for the file that
handled that stuff.
The last question then is if there is a way to add "ip rule" rules to
specify which routing table to use based on packet information.
ex: ip rule add fwmark 3 table 3
Are any of the network scripts able to handle this as well?
Thanks again!
Eric
