Title: GRE Protocol VPN PPTP Post by: mesi on Wednesday 06 June 2012, 12:46:26 am 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 Title: Re: GRE Protocol VPN PPTP Post by: kashifmax on Thursday 07 June 2012, 10:29:14 pm 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...
Title: Re: GRE Protocol VPN PPTP Post by: mesi on Friday 08 June 2012, 04:12:32 am 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 Title: Re: GRE Protocol VPN PPTP Post by: kashifmax on Sunday 10 June 2012, 07:42:45 pm 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... |
