router pc problem, internet stopped working, lan works, using rc.firewall
slackware 10.2/2.6.17.8 pc using rc.firewall script from easy firewall generator, two nics, cable modem connects to nic1, nic2 connects to a switch, other pc's connect to the switch
everything worked fine for like 24 hours then internet access stopped, lan access still works, rebooted pc, reset the switch, no affect
seems like a nameserver problem but i checked the dns ip's and they havent changed
ssh logs in slow with this happening
what can i use or do to diagnose what might be wrong and where
i can provide additional information as necessary, thanks

Suggestion, re-install Distro with the actual MAC Address. After the reboot and settings applied as YOU prefer, then tweak the firewall/IPTables or other filtering. Because there are so many files with the MAC Address association, the fresh install will lessen the complications down the road towards YOUR system being setup YOUR way.
