Hi,
I am new to Mikrotik, I have a RB1100AHx2 connected through Ether1 to the LAN and PPPoe client is connected Ether2 I want to forward all the pptp request coming to my Mikrotik at Ether2 interface to be forwarded to my windows PPTP VPN server which is available in the LAN. Other port forwarding are working just fine, I have forwarded both the port 1723(tcp) and GRE to the server address.
Please help me if any one how to forward the PPTP traffic to the windows VPN server
This may be the solution to your problem:
/ip firewall nat add action=dst-nat chain=dstnat dst-port=1723 in-interface=Ext-IF protocol=tcp to-addresses=192.168.9.5
/ip firewall filter add action=accept chain=forward in-interface=Ext-IF protocol=gre
/ip firewall filter add action=accept chain=forward out-interface=Ext-IF src-address=192.168.9.5
Have a look at this topic: http://forum.mikrotik.com/t/pptp-forward-port-not-working/58722/1
You should use the pppoe interface as in-interface
