Hardware firewalls also slow your connection down.;)

That too, and they make for a pain in the ass time trying to set up Internet game servers for games like the BattleField series.

Freyr;4217815Avast is not a firewall and if he's trying to block connections (such as a cracker connecting to use the windows remote exploit of the day) then its of no use whatsoever.

Zone Alarm is a decent software firewall. Other than that you can use a router's NAT mode and only forward on stuff to your computer that you actually want. Otherwise your computer is not even addressable from the internet except for programs you have specifically configured. Thats how mine is setup.

Great info there.

ZoneAlarm is probably the best software firewall IMO. That said, hackers can sometimes find exploits in software firewalls. When configured correctly, a hardware firewall can make you completely invisible on the net. In otherwords, I totally agree with Freyr.

EpicLoad;4222096I don't really trust Hardware Firewalls, the main reason being that my router was set up by my father to have a Firewall without security. Plus that, I like having a more direct control of Firewall access.[/quote]

You do have access, you just have to log into it. Well, ok. Your father has access and you don't. Given the level of knowledge you have demonstrated here I don't think its a good idea you have access to a live firewall before you have learnt a bit on the subject first.

Having a firewall with everything allowed is like a bucket holed like a sieve. IE completely useless. That having been said, from what you said about being a pain with one of your games it was probably doing the job to some degree, even if that was more by accident than design.

EpicLoad;4222693That too, and they make for a pain in the ass time trying to set up Internet game servers for games like the BattleField series.

... Only if you have no idea what your doing with firewalls. You just forward the relevant ports onto your internal IP. For instance, to run a web server on your computer assuming your internal IP is 10.0.0.2 all you would do is make these entires in the firewall/NAT:-

TCP *:80 to 10.0.0.2:80 TCP *:8080 to 10.0.0.2:8080

If you don't know what your doing and you can't read a manual or one of the countless howto's on the net then, sorry but thats not a problem with the device. IMO properly configuring a NAT is one of the easiest tasks you can get in IT. [quote=>Omen<;4222638]Hardware firewalls also slow your connection down.;)

Only if it was designed for 56k analog or 128k ISDN. Otherwise you shouldn't notice any appreciable difference if it is properly configured. Unless your doing gateway scannning for viruses before passing them along to you of course. Thats common in a business but hardly likely in a home system.

Not true at all in my experience, which is why it's been some time since I've used one. I still have the Linksys BEFSR41 (version 2) router I used to use on my broadband DSL connectrion and it's just collecting dust. My speed checks with it even on 1.5MB service always showed much slower speeds no matter how it was configured. The only thing that comes close to being an exception to that is with devices like Qwest uses for their DSL modems which come stock with all ports open. You have to firmware flash them to add firewall protection and when you do the speed drops, even Qwest will tell you that. Thus it's not really an exception because stock you don't have a firewall.

Unless you accidentally discovered some traffic shaping options, buggered up your config by setting both the router and modem as the same internal IP address, or used a bit of telephone cable instead of CAT5E I don't see how you would possibly end up getting a slower connection.

Its not like an extra couple of meters of cable and one forwarding point makes a huge amount of difference to the distance the average packet travels. The only difference you should see is a 1ms delay on forwarding which is imperceptible to a human.

Yes, extending a device beyond its design parameters is a bad idea. No, devices designed to offer NAT or firewall functionality are not going to slow a connection down.

All I can say is I did the speed tests to verify it. The rest is mumbo jumbo as far as I'm concened.

Mumbo jumbo is asserting that any and every hardware router and firewall will degrade network performance based on your experience with one singular device.

That is nonsensical, especially considering you can buy cheap devices that act as the NAT as well as the modem.

Ouch, that kind of hurts *not really*. I understand though, I'm currently taking a networking class and learning all of this stuff, and I don't care to take the time outside of school to learn it. Also, on the subject of opening ports on the firewall to allow battlefield servers, the only problem I have with it is some of the people I'm trying to play with cannot connect while others can... but we haven't taken that much time trying to solve it.
