VPN Port-forwardinf & Passthrought

Hi buddies!

In my office we use a lots of VPN's from ours custumer and we had a lynksys e1200 with port forwardinfg for PPTP, L2TP and IPSec Passtrhought, right now we have migrated to a 2911 with CME features to manager SIP phones.

I'm not and expert on the security area and withthe ISR we cannot connect to a customer VPN that uses PPTP (Windows) how can I make the portforwarding and passthrought on this new router?

The interface Gi0/0 is to the ISP with NAT outside (PAT)
The interface Gi0/1.1 is our LAN with NAT inside (PAT)

 

I have integrate a the basic and lower default firewall that generates Cisco Configuration Profesional, but with or without this firewall we still cannot conect!

 

Best Regards!
