Setting firewall to run PPTP

Hi,

can anyone tell me how I can setup firewall rules to accept PPTP connection from ,outside, world.
I have firewall and PPTP server in the same router.
(Firewall is between DSL (PPPoE client) and LAN).

Thanks for ideas

PPTP is not actually secure these days, so I assume you have strong reasons to use it anyway.

Normally it is sufficient add a rule permitting incoming connections to TCP port 1723 into chain=input of /ip firewall filter if the default firewall rules are in place. The default firewall settings accept “related” traffic and the PPTP “helper” adds GRE connection from the client address as a “related” one.

If the above information is not enough, follow the hint in my automatic signature below.
