How to open up a port?

[Ehsan]

I have installed Oleg's firmware on my Asus WL-500g Premium router. I've also installed ctorrent and YODCTCS Web Gui for administrating the torrents. The web gui uses port 18000 for access. This works fine when I sit at home but I would like to be able to access the web gui externally so I can start and administrate downloads when I'm not at home. So I figured I need to open up port 18000 for external traffic.

Now how can I accomplish this?

Any ideas?

Try to create this rule with iptables:

iptables -I INPUT -m tcp -p tcp --dport 18000  -j ACCEPT

eventually put it in /usr/local/sbin/post-firewall so it will be reinitialised in case the router is restarted, like this:

 echo "iptables -I INPUT -m tcp -p tcp --dport 18000  -j ACCEPT" >> /usr/local/sbin/post-firewall

..and don`t forget to save it:

flashfs save && flashfs commit && flashfs enable

to save it.

Or try

iptables -A INPUT -p tcp --dport 18000 -j ACCEPT

It`s about the same thing.

Cheers.
