I'm having trouble with my slackware 10 linux box which acts as a router for the rest of my network (2 NICs). All of the services on it work perfectly from my other computer (xp home) on the network but i can't access anything from outside of it- http doesnt work, i can't send email from the network. I can access websites and aim and such. I'm using the simple firewall configuration rc.firewall-2.4 script that comes with the ip-masquerade howto. If it means anything, when i try to use the more secure version (rc.firewall-2.4-stronger), i get the error message:
Starting mysqld daemon with databases from /var/lib/mysql
/usr/sbin/nmbd -D

SIOCADDRT: Invalid argument

and nothing starts.
Is this a firewall configuration problem? It looks like the ports are open:

I'm not sure if these problems are related or not. Thanks for any help you can give!
