Iptables vpn connection

[Guest rodama]

I tried researching on why I cannot connect to my centos 6.5 vpn server.

 

I am using centos 6.5 configured with vpn using this tutorial steps:

1.yum install -y git

 

2. cd /opt && git clone git://github.com/drewsymo/VPN.git

 

3. cd VPN && bash vpn-setup-vanilla.sh

 

I have also added these to permit vpn connection in iptables:

 

It seems that the default iptables rules allows ssh (port 22) . If I enable iptables I can ssh my server but cannot connect to vpn port 1723.

 

 

My current iptables configuration is as follows:

 

# Generated by iptables-save v1.4.7 on Thu Jul 3 02:33:59 2014

*filter

:INPUT ACCEPT [0:0]
