Good reccommendations for web protection (firewall)?

Question for the computer people:

Having wireless internet installed this Thursday (thanks to an anonymous friend of a friend, I got my install date pushed up about 2 weeks ) I've got 3 PCs here (2 WinXP, one Linux) and figure maybe it's a good idea to put some sort of firewall or something in between me and the web. I only need to get "out" on one PC - but would like all 3 safe from attack..

What do y'all recommend? Is this what a DSL Router does? With this device in place, will I still be able to play online games, etc?

Thanks!

McAffe has a decent firewall. Norton is not bad either. Some routers have built in firewalls but I'd still use on on the computer also.

Yeah you still will be able to play games online. All teh DSL router is, is to split up the bandwidth between computers in the home network enviorment.

I'm not crazy, my mother had me tested.

So the DSL Router is basically nothing more than your basic hub (or maybe a switch, a little better), but it has "DSL" written on it so people with DSL will buy it?

I figured it'd have a firewall built in.... ok, fine tho. That means I don't have to buy a separate box then.

Somebody on another board I'm on suggested I use my Linux box as a firewall of sorts... that's doable... any idea how hard it is to set this up?

Keep in mind I am computer literate - but NOT networking-literate...

A router is basically a hub and switch built together from the way it was explained ot me. I dont know if DSL needs a differetn router than cable modem (I have a D-link router with print server so I can get cable later and network my other computer upstairs to use the same printer).

I'm not crazy, my mother had me tested.

Well... that's just it. I actually had DSL hooked up at my dad's a few years ago, and just used a simple 10/100 hub. I had the DSL modem connected to the hub's Uplink port - and had NO problems logging on from either of the PCs on the network (one running 98 and the other on 2k.)

It wasn't until probably 6 months later that I started seeing "DSL and Cable Routers". I wasn't sure if it was just BS, or if it served a purpose. Just like the "Music" CD-Rs vs. the "Data" CD-Rs. You can buy 1 CD-R for like $5 in the music section of Best Buy... but can buy a 10-pack for the same $5 in the computer section. No difference, other than one says "music" on it. So apparently, a "DSL" router is nothing more than a router, with "DSL" written on it, to dupe people into thinking that they need this $150 router, vs. the $29 hub next to it.

I figured as much. Thanks Rob.

It's for Windows. I don't know if they have a Linux version but you shouldn't have much problem finding something in the Linux world.

routers are made for both cable and dsl... only thing they have is a built in hardware firewall which is better than software. u can still play games with it.. u just have to open up ports to game on.

I'd have 2 network cards in the linux box, 1 for the Dsl connection, one to connect to another hub. The other hub would then have the other 2 windows machines connected to it.

Linux has great firewall software that is also free which is the beautiful part. Check out www.freshmeat.net if you didn't know already for more apps then you could ever dream of. The linux box would then protect itself and the rest of the computers on the network.

I think the cheapest, and best, way to go for you is to install a second NIC in your linux machine and use it as a firewall. You didn't say which distribution that you use, but all newer distros come with a fireall package. Usually IPFilter now. Basically for the cost of a NIC, around 20 bucks or so now, you can get more features than you'd ever get from a 99-200 dollar 'broadband gateway'. If you need an IPFilter script, let me know. You should be able to download the binary, or source files and compile it on your system.

I've used Linux for firewall services for years without a problem. Once you get setup, you can remove the keyboard, mouse, and video from the machine, and never touch it. I put a machine in my mother's house two years ago, and she never has to touch it.

BTW a router is a device 'read computer' that transfers information from one network to another. Basically it's responsible for moving the data from your home network to the Internet network. A hub is an Ethernet device that allows multiple computers to exist on one network. A switch is similar to a hub, but is able to dedicate bandwith to each port on the switch, whereas on a hub the bandwith is shared between all devices. They all look alike but functions are different.

Typically the DSL or cable routers sold on the market, have nothing to do with DSL or cable. They are all basically ethernet routers, unless they have an actual coax or RJ11 jack on one end. Most just have an uplink port that you'd connect to the ethernet port from your cable or DSL modem, and 1 or more ethernet ports for you to plug your computer(s) into.

There is also no such thing as a broadband modem. Modem is Modulate/Demodulate, or converting analog noise to a digital bitstream. Cable and DSL networks are already digital. The 'modems' are usually either bridges or routers. People just identify better with the word modem.
