ANSWERED Port Forwarding Issues through Rasberry Pi Gateway

[sooprtruffaut 5]

Hey,

I have set up AirVPN on a raspberry pi and configured the pi to be a VPN gateway for my home. The gateway is working fine and I want to expand its capabilities to act as a seed box. Transmission is now install on the pi and working fine, except I can't open a port on the pi for uploads. I believe the fact that the pi is acting as a gateway as well and has specific iptable rules established is complicating matters. I have also followed the instruction on the site about p2p port forwarding so if you can offer any help with this matter I'd very much appreciate it!

These are the iptables for the gateway. What rules should I add so that I can open a port through Air's port forwarding page? 

Much obliged.

iptables 

sudo iptables -S

-P INPUT ACCEPT

-P FORWARD ACCEPT

-P OUTPUT ACCEPT

-A INPUT -i tun0 -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT

-A INPUT -i tun0 -j DROP

 

sudo iptables -t nat -S

-P PREROUTING ACCEPT

-P INPUT ACCEPT

-P OUTPUT ACCEPT

-P POSTROUTING ACCEPT

-A POSTROUTING -o tun0 -j MASQUERADE

Change -A INPUT -i tun0 -j DROP to -A INPUT -i tun0 -j ACCEPT and remove the above conntrack rule.

There will be more sense to add NEW to conntrack states if you plan to use it anyway, otherwise new connections cannot be accepted.

Ah, that's fantastic, zhang888. Thank you very much! [谢谢你?］That's fixed things for me. The port in question is now open.
