A MS VPN client through an iptables FW

Hello,

I have setup a Linux firewall using iptables. I am working on allowing
VPN connections using Microsoft VPN client from inside my network to a
Microsoft VPN server outside my network.

In other word, the Microsoft VPN client initiating the connection is
inside the firewall and the Microsoft VPN server is outside.

I tested the connection without my firewall and all works.

Any help is appreciated.

Tanks.

I found the solution :

# allow GRE (MS VPN Client)
$IPTABLES -A INPUT -p 47 -j ACCEPT
$IPTABLES -A OUTPUT -p 47 -j ACCEPT
$IPTABLES -A FORWARD -p 47 -j ACCEPT
