  sorry contradict miguel, port 47, tcp or udp, has nothing with pptp.

  cause problems pptp gre, pointed out.  confusion arises because gre is internet protocol 47. even manufacturers' documents mention port 47, has nothing with pptp really.

   pptp packets use modified gre header. if in path blocks gre protocol, no packets cross link , closes.  


   sebastian,

      vpn setup work locally? can connect lan machine? if not, server config problem can sort out locally.

    error message when try connect remotely? if gre problem error 721.
