Need help with PPTP and Firewall

I configured my MTs like the manual in the wiki (http://wiki.mikrotik.com/wiki/Manual:Interface/PPTP)

It works only when i disable the firewall. Wich entrys do i need to set in the firewall settings? I use winbox to configure the Routers.

I need two configurations.

  1. only traffic over the PPTP VPN is allowed. We only want to get access to the shares on the server which is located at the other side of the vpn. No more Internet access is allowed.

  2. the same like above but with internet access allowed.

can you give me advise how to set this up?
sorry for my english but i hope you can understand me.

Oh, i use the RB750 with Os 4.10

In input chain you have to accept gre and tcp/1723(pptp) then tunnel will work

It doesn’t work for me.

My settings are

Rule 0 Chain: input Protocol: tcp src and dest 1723 action: accept
Rule 1 Chain: input Protocol: 47 (gre) action: accept
Rule 2 Chain: input action: drop

where is the problem?

EDIT: I’ve found the problem. i must use dst port and not src und or dst.
