Why other gamers wouldn't help with that info is really unclear.
Well they did 'help', but not really. See for yourself if you want: http://www.wilderssecurity.com/showthread.php?t=288497
First I was given some jargon, then I was given a link to a 100-post thread that had jargon in every post and was a real-time account of someone experimenting with getting multiplayer to work with LnS. When I said I couldn't possibly understand it, I was told to ask what I don't understand. When I explained I don't understand it at all because of how advanced it was, I was ignore dand they starte having other conversations with other people. Eventually someone replied saying I had already been shown help, linking to the thread again.
So I said my...goodbyes.
Facepalm.
Thanks for the links, although I figure the one from 2005 might not be useful nowadays. Back when Norton and Windows Firewall were terrible, for example. 
Maybe I'm misunderstanding, or have been misunderstood. I assumed the OP was asking about firewalls only, not the bundled firewall+AV and/or internet protection suites, or the like.
I mentioned ZA free version for a firewall only, and mainly to notice/prevent outbound connections -- not outbound connections from malware/etc. so much as from 'legitimate' programs that are calling 'home' to report on things that aren't necessary IMO (although being notified of an outbound connection attempt is a good way to spot malware that's gotten through).
Sorry if I was unclear or am misunderstanding...
I AM the OP. 
I was only talking about the ZA firewall too, I already have an antivirus (NOD32).
There are several sites sharing these Forums...where some topics such as this one appear on ALL the sites as "Personal Computing" [for example] applies to all of Stardock's users/customers and is thus accessible from/on all the sites...
Well, how queer.
As someone just into some games over the past year and a half, I have been severely frustrated by the lack of support from some of the developers. I ahve run across issues and found dozens of threads that cover these issues that the develepors will just let die with no resolution of any kind. Blizzard has to be on of the worst.
I had Yrag on the phone trying to figure out the last one. It took me three weeks to find a solution and it was from a non-gaming resource. I think the thread I started is still dead in Blizzards forum.
Forums are flawed and are not a breeding ground for help, peace and happiness. Other than to ask something, people usually come on forums to complain or make themselves feel better by belittling others. This is exasperated by the fact that people who are given modding duties are people who spend their life, or too long, on the internet and thus go mad with their imaginary power. Some forum mods have 'factions' having a go at each other in their super-secret mod forum, while others talk about themselves like they're the FBI or mafia, it's nuts yet saddening.
Anyway, places like Lucas Arts' forums are dead, LnS (as mentioned) and Steam can be or is elitist, while Sports ineractive has a lot of fan interaction, feedback and developer posts and help, it's just that the regular users on there are generally none too sharp.
But it can be a different story contacting the developers themselves. I got a lot of help when Knights of the Old Republic wasn't working, it even got down to registry keys and other hallowed computer ground. Plenty of emails were exchanged without stopping, until it all worked out in the end.
It's important not to confuse a 30-something developer (with a house) with a 20-year-old forum regular (with issues).
