Issue Plesk Onyx (17.8.1) Firewall Settings To Enable PPTP connection.

[ArshadM]

In the past I have been using PPTP succesfuly by following the procedure as described at Install PPTP on CentOS 5 - CS Labs Wiki ,

while not enabling Firewall in Plesk Contol Panel
but enabling firewall in Plesk Virtuzzo and selecting option Advanced firewall mode with default policy Accept

Now, when I enable Plesk Firewall with the default firewall rules & run the script covering the below list of commands, PPTP starts working, however other services such as mail, ftp etc stop working and iptables -L shows limited details. When I restart the server all settings are reset to default firewall rules but PPTP don't work.

#!/bin/bash
/sbin/iptables -F
/sbin/iptables -P INPUT DROP
/sbin/iptables -P OUTPUT ACCEPT
/sbin/iptables -t nat -A POSTROUTING -o venet0 -j MASQUERADE
/sbin/iptables -A FORWARD -i ppp+ -o venet0 -j ACCEPT
/sbin/iptables -A FORWARD -i venet0 -o ppp+ -j ACCEPT
/sbin/iptables -A INPUT -i venet0 -p tcp --dport 1723 -j ACCEPT
/sbin/iptables -A INPUT -i venet0 -p gre -j ACCEPT
/sbin/iptables -A INPUT -p icmp -j ACCEPT
/sbin/iptables -A INPUT -i lo -j ACCEPT
/sbin/iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
/sbin/service iptables save
/sbin/iptables -L -v


Now how to add firewall rules in Plesk (onyx) to allow pptp connection covering the above details ?

Is there any default rule which can be added to allow pptp connections at port 1723 ?

Regards.
