Shibby Tomato 1.28 Firmware – Asus RT-AC68U – PPTP VPN

Hi Guys,

We have just installed a Asus RT-AC68U Router and have to say were very impressed. One area that could have been a little more in-depth was the firmware but, being open sorce firmware capable we decided to use Shibby Tomato 1.28. If you have tried getting a PPTP VPN tunnel initiated you will be like us and many others having issues, after trawling the web we found it:

Add this scipt below to the Administration/Scripts/Firewall section:

#!/bin/sh
iptables -A INPUT -p gre -j ACCEPT
iptables -A INPUT -p tcp –dport 1723 -j ACCEPT
iptables -A INPUT -i ppp+ -j ACCEPT
iptables -A FORWARD -i ppp+ -j ACCEPT
iptables -A FORWARD -o ppp+ -j ACCEPT

iptables -t nat -I PREROUTING -p tcp  014dport 1723 -j ACCEPT
iptables -I INPUT -p tcp  014dport 1723 -j ACCEPT
iptables -I INPUT -i ppp+ -j ACCEPT
iptables -I FORWARD -i ppp+ -j ACCEPT

Then as is plastered all over the web just click save and thats it however thats not just it, you then need to go to the Advanced/Firewall section, and just click SAVE to restart the firewall services. Now all will be working… 🙂

It took quite a while to work this out and hop this will save others time, hopefully Shibby will implement this into the firmware so you dont have to manually do this, if you enable the VPN Server it should just work

We have just discovered that using this method that is widely talked about throughout the web opens up some security issues. As soon as we learn how to patch it we will post the solution here, in the meantime please do not use the code above.
