how to use iptables with gargoyle firmware?

[plopes1960]

Hi all!

I have a tp-link wr1043nd running the latest version of gargoyle.

It's setup as a router (wired) with openvpn client running.

I need to setup a few iptables like those:

Code: Select all

iptables -t nat -A POSTROUTING -o tun0 -j MASQUERADE

iptables -t nat -A PREROUTING -p tcp --dport 13000 -j DNAT --to-destination 192.168.1.5:13000

iptables -I INPUT 3 -i tun0 -p icmp -j ACCEPT

How and where can I do this?

Many thanks for your prompt answer Lantis!

after log in on cli, should I simply run those commands one by one?

Yes you run them 1 by 1.
But i don't know what they are intended to do or why. And can't promise you won't cause unexpected behaviour from Gargoyle.

But on the first reply, you said by command line.

Ok I got it.

However, I still confused how to manage the iptables on gargoyle firmware.

Anyone can give me a hand?

Hi, you can easily add them to the running iptables rules, to store them so they are active after next powercycle however is another story. either you have to find where the rules are stored, and add them there or you need to add a new rule in crontab for adding these rules at every boot
