Masq BOX problems..

[Ryan Bethke <immortal26@prodigy.net>]

I have a masq box set up, and all was running fine until recently when I could
no longer recieve packets from websites, the first one I noticed was
www.linux.com, every couple of days a new one pops up that I cannot connect to
with my computers behide the masq box.  The strange part is that I can connect
to these sites from the masq box no problem.  I don't have any rules set up to
block out these sites.  

I am running a modified Slackware 4.0 install, with kernel-2.2.9.  

Does anybody have any suggestions?
