logger -t masq-firewall -s "Allow PPTP Server Connections on port
1723"
$IPCHAINS -A input -j ACCEPT -p tcp -s $ALLADDR 1723 -d $ALLADDR -v
$IPCHAINS -A output -j ACCEPT -p tcp -s $ALLADDR -d $ALLADDR 1723 -v

logger -t masq-firewall -s "Allow PPTP Server Connections on port 47"
$IPCHAINS -A input -p 47 -j ACCEPT -v
$IPCHAINS -A output -p 47 -j ACCEPT -v

That should fix you up. These are not neccessarily the BEST rules to
use, but they worked for me for about 8 months with no problems. Now
I use iptables.

BTW, you REALLY should consider moving up to kernel 2.4.x. Check out
my site...
http://linus.yi.org. Got a page for the Masq stuff, and one for the
ppp/pptp stuff. Check it out.
