Re: [newbie] Firewall Oddities
Thanks for the help Derek. /etc/shorewall/interfaces only had my wireless card (eth1) set to the loc zone, instead of net. After setting it, it's now working great.

RE: [newbie] Firewall Oddities
Take a look at the two-nic firewall sample config. It is substantially different from the one-nic config that many use. I bet you'll find the issue there. On a side note, the configs are very simple. Since I got familiar with them, I haven't gone back to the MCC for firewall management.
