no, i just want to forward through the built-in firewall, at the moment the only ports that are open are default ones that are throttled by my isp

Is there any chance perhaps that you would give us more details? I am out of crystal balls at the moment, my wife isn't good at Tarot cards, and palm-reading goes too far into my sex life ... and there aren't any gypsies around that I could hire to take a trans-dimensional exo-corporeal look at your setup ... I could smoke these funny-looking mushrooms, but I don't have time for the three-day orgy that usually ensues afterwards .... :D

So we will have to rely on nicely written detailed sentences that you will have to write for us, yes? :wink:

All we know right now is that you appear to have a router with a built-in firewall and that you want to forward TCP port 51098 through it. Based on this amount of information I'd say you're either in need of posting a lot more than that or you should maybe take a close look at your router's manual ...

Sorry if this sounds rude, but the small amount of information that you provide makes it next to impossible to help you. :roll:

Please provide more details. *Far* more details. :lol:

Yes, there is a firewall. But unless you activated it somehow (e.g. via a program such as firestarter ...?) it is not active. So whatever TCP traffic your WAN-router is forwarding to your home network should not have any troubles reaching your Linux machine. And if there is a process or program listening on the right TCP port (e.g. a p2p client configured to do exactly that?) then the connections should be established OK. So as I interpret the infos you gave so far you probably will have to configure your Internet router (what brand is it? Linksys? Netgear? D-Link? ...) to forward the traffic on port 51098 to your Linux machine's internal IP address and that's it.

OK, now I get it :lol: ... Sorry if I was a bit too harsh in my previous posting. My apologies :oops:

Well, the firewall is a Linux kernel feature (the core + heart of the operating system) so you can't really remove it without changing something in the kernel. But to answer: No, unless you're directly facing the internet and/or running any services that are accessible to the outside world (e.g. a web site, a forum of some sorts, etc.) then there is nothing that would require the protection of a firewall. That's as far as I can tell the reason why it is off per default.
