I curently have Mandrake linux 10 and webmin installed I can not for the life of me get port fowardign to work using webmin and the shorewall modual.I dont know what else to do so here. i am im pleading mercy that some one can help me. here is what i want to do i curently have a linux box acting as a roughter/proxy and 4 windows systems one system has emule on it and its configured to use port 4662tcp and 4800 udp on the system with ip of 192.168.1.251 so im wanting to get the roughter to foward to that port so emle will work but so far all i have done in gohn in circles installed every other firewall for linux i could find and now im back at my defult settign (and btw i thing next time i buy linux im gettign the dvd cause swaping the 8 cd's around sucks) iv reloaded linux so many times im just sick of its and at my wits end any one please help. (BTW i know nuthing abought the scripts and this is my first linux server and im building up a learning curve but its going slow.)

Instead of installing every other firewall and "reloading linux", maybe you could try to learn something about how the firewalls actually work. What you are trying to achieve is not that difficult, I bet with a good iptables tutorial, you'll be done in an hour or two.

Iv been tinkering but still no luck. I'd read a good tutorial if i could find one that didnt confuse me. Im still learnign linux, it is a steep learning curve from windows, and i mostly learn from doing. If i mess it up to bad i have been reloading it and trying again. The reason Iv installed the other firewalls is a wanted to see if there was a beter option than what came with linux i was using firestarter for a while and had it working but wasnt to impressed with it, as the interface kept locking up and not fully working right. I like linux and im having fun, but its just kinda flusteriating. 99% of the documation iv found asums that you know a bunch abought linux and loose me quickly. i like the feel of linux but just wish i knew more abought it. When i start digging in to scripts im afraid ill fubar it and have to reload it again and hear the wife yell at me. ( nathan what did you do to the internet why cant you just leave it alone. Then i have to try to explain that it dont do what i want it to.) but any ways here is a config test maby you can make sence of it.
thanks

Hey Nathan, welcome to LQ.org!

I'm afraid I can't help you specifically with your firewalling problem, but I have a suggestion which may take some of the frustration out of learning linux generally. Check out the RUTE Users Tutorial and Exposition. It's perhaps the most comprehensive guide for learning linux from the ground up. If nothing else, this guide can help you to understand what they're talking about in those iptables tutorials.

Enjoy!
