PPTP server + Firewall + PPTP VPN Masq through firewall

[Evan Davies <evand@xxxxxxxxxxxxxxxx>]

Hi All,

I was wondering if the following was possible:

Windows Client
PPTP VPN Client  ----\
                                  \
Linux Client ---------->------> FIREWALL + PPTP Server --- INTERNET ----- FIREWALL + PPTP Server
                                   /                              |
Windows Client ------/                                |
                                                                   |
                                                            Home User PPTP VPN


I can have the Firewall/ VPN server work correctly in that the home user can connect. But the internal PPTP client  cannont make a connection out through the firewall.

I turn the VPN server off and adjust the iptables rules so incoming 47 connections are blocked and the internal PPTP client connects no problems to another external pptp server.

Is i possible to have both connections running ?

I'm using RH 8.0 with iptables 1.2.7a + pptp_connection tracking module is compiled into the kernel but not as a module.

Can anyone give me an example of an iptables script to do this


Any help would be greatly appreciated
