At the moment I am unable to get L2TP between OSX and zeroshell functioning. So for the time being I am attedmpting to setup a PPtP server on my LAN to allow me to remote into my network. I have added port 1723 to the Virtual Server section and I have added a rule to allow GRE incoming from my external interface.
From the logs of my PPtP server it is getting my requests but I am not getting replies.
Any ideas what I can do.
TIA
