You don't have to add any special filter rules for GRE, that is taken care
of by the filter ruleset generator automatically. But if you use
m0n0wall's built-in PPTP server (i.e. you do not redirect incoming PPTP
connections to another PPTP server behind the firewall), you'll have to
add rules on the "PPTP" interface to permit traffic from them (example:
interface PPTP, protocol any, source PPTP clients, destination any).

What do you want to do now - use the built-in PPTP server or redirect the
connection? With the latter, you also have to be aware of issues that 3rd
party PPTP servers may be having with NAT...

HTH,
