You have not given full details.

You need to check 

1. You need to allow GRE protocol through your firewall
2. Assuming you are using NAT, you need to compile support for pptp connection tracking in kernel. Please note that conntrack_pptp is not part of stock kernel. Have a look at www.netfilter.org. Else, only one remote PPTP session works.

  Subject: Connecting to PPtP Servers from a LAN


  Hello everybody,

   

  we have set up a simple firewall configuration:

   

  ournetwork   -----------------   Router with iptables ----------------Internet

   

  the router with iptables does Masquerading on outgoing Packets from the LAN.

   

  When connecting to an PPtP Server in the Internet, connection does not work.

   

  When trying it with the old router, an Windows Winroute Router, the connection works fine without configuring anything.

  What  rules do I have to configure for my Clients, so that they may access an PPtP-Server localted in the Internet?

   

   

  Thanks in advance,

   

  Alex
