GRE Protocol VPN PPTP

[Guest]

[mesi]

I'm trying to open the GRE id. 47 protocol on the firewall but I can not make it work. With the firewall we had before, we had no problems (iPCop).

Can anyone tell me if you have to do anything special in this firewall to open the GRE protocol? I have a VPN server stopped by this problem, and I see I'll have to go back to my old firewall.

thanks

I think you don't need any special setting in EFW (2.5.1). But anyways you mentioned that it was working with IPCop. I assume that you enabled 1723 port in firewall (incoming/outgoing) ? Also enable logging and see if anything is dropping by firewall/OpenVPN...

Yes, I have the port 1723 open (incoming/outgoing). I see in the firewall the VPN access, and is correct. And the server receives the access

PORTFWACCESS:ALLOW:3 TCP (eth0) 213...:44085 -> 192.168.12.16:1723

But the GRE traffic is blocked on the firewall, or that's the only fault I see...

Thanks

If you have opened the port (incoming/outgoing) than in the logs, it should be shown like OUTGOINGFW/INPUT not PORTFWACCESS ? And for VPN it should be shown like VPNFW in logs.

Kindly describe your scenario or issue clearly...
