PPTP VPN - Windows 7 (Blocked Transit Packets)

[jockeylol]

Hi,

I have created an incoming connection on my windows 7 machine (PPTP : 1723). I also added the rule to allow TCP 1723 and GRE 47 in outpost global rules. The VPN connects fine, also assigns a dynamic local ip (192.168.1.X) to the client machine, but here is when the problem starts. All the packets are blocked due to the source/destination IP mismatch.

Log text :

N/A TCP 192.168.1.35 60634 Block Transit Packets 0 52
N/A TCP 192.168.1.35 60634 Block Transit Packets 0 152
N/A UDP 192.168.1.35 NBT_DGM Block NetBIOS Traffic 0 2 104
N/A UDP 192.168.1.35 BOOTPC Block Transit Packets 0 656
N/A UDP 192.168.1.35 54162 Block Transit Packets 0 324
N/A UDP 192.168.1.35 56868 Block Transit Packets 0 324
N/A UDP 192.168.1.35 NBT_NS Block NetBIOS Traffic 0 5 382
N/A TCP 192.168.1.35 60657 Block Transit Packets 0 104

I have tried adding low level rules allowing ICMP,UDP,TCP for the remote address and even tried opening 1024-65535 (all) the ports. Nothing seems to work here.

The setup is as follows :

Server - Windows 7 machine (IP - 192.168.1.X) behind a router whose port 1723 has been forwarded to it

Client - Windows 7 machine behind a router as well (IP - 172.16.10.X)

Searched the forums, tried almost everything, no gain. Maybe I missed out on something as I am not a network expert, hence unable to figure this out.

Try enabling NAT zone for the VPN server.

I have already tried that. It doesn't solve the problem either.
