        I can sign in and check the settings of my modem. Is that what you mean?

          Is your setup bridging or routing?

              And you're having double nat with pfsense?
              so that pfsense has something like this:
              wan: 192.168.100.10 /24
              lan: 192.168.1.1 /24?

                Yes, I have

                Lan: 192.168.1.2 / 24

                Wan on DHCP: range 192.168.15.x / 24

                As extra information, I'm doing NAt on port 80 and forwarding to one IP in the subnet.

                  Well,

                  GRE is part of ip, but not tcp or udp, it's not a port which you can forward to, unless you're having separate support to it.
                  If it is possible by anymeans, change to bridging configuration and then GRE should work a bit better

                    Got ya!!!,

                    I wouldn't like to switch to brigde mode since I can lose some of the advantages over routing. Meanwhile I'm accessing the VPN from a pc out of the firewall.

                    Now, what is the GRE tunneling on Interfaces used for?

                    Thanks in advanced again for all your time and help.

                    Joe

                        I focused on the advantage of routing over bridging in a firewall. I can not tell on the modem. I've bin trying to find where I can switch my modem to the bridge mode without luck. I'll check GRE on wiki. Any suggestion from you is valuable.

                          I only tried to suggest that, change your modem to bridging and use only firewall in routing mode.
                          that ease a bit to troubleshoot gre and other things also.
