Unhappy How do i tell if my router has a firewall?
(please bear with me, i am very bad at computer hardware)

Ok. I have this black box that came with the comcast internet, it is by motorola. and then i have this other box that came with my wireless internet, it is a belkin. the cable goes through the motorola box, to the belkin, to my laptop.

How do i tell if i have a firewall?

If i do have a firewall, how do i configure it? --I havnt seen anything that looks like a config for the motorola box, which i think is my router.

So leme see if I understand this....
You have cable internet right? (most likely the Motorola)
So you have a cable line that runs to that Motorola?...

True so far?

Then from the Motorola it goes to a wireless (?sender?)???
No other computers are using this connection?

Edit: Oh and this probably should be moved to "networking"

If it is a router, then the router it self is used as a firewall... (<<< that is my understanding any way.)
You'll need the model # in order to tell you how to get into it and configure it..
(Most likely you won't need to)
If it's just a wireless antenna then it's not a router...
Just need the model # and we can know for sure.

If your concern is to stop spyware you'll need other programs for that..
I like and use "Spybot SD" "AdAware SE" and "Spyware Blaster"..
Also a good antivirus program is needed...

The NAT layer in any SOHO router is the major "firewall" component. There are other advanced firewall features that come with most new SOHO routers, SPI, IP and URL filtering, etc.

If you got Stealth on all ports then your doing great and your have a perfect "TruStealth" rating.

Post the model number from the device you are asking about. You MAY have a wireless access point, not a router.

The NAT in any router is certainly NO substitute for a good firewall. NAT provides minimal/basic protection and if you're counting on that as a primary source of defense - you'll eventually come to regret it.

the cable goes from the wall, to the motorola, then (i think its called an ethernet cord, the thing that looks like a phone line) goes from the motorola to the Belkin, and then another cord goes from the belkin to my computer.

i am the only one that uses my computer.

the belkin box is a "2.4GHz - 802.11g Wireless" Model # -f5d7230-4

I now know that the belkin is a wireless router, and the motorola is a cable modem.

the motorola is is: "SB5100 SURFboard Cable Modem"

Tushman, I'll have to disagree with you on your point. In any case, you'll notice that most current SOHO broadband routers include a lot of additional firewall features.

I've run with no other firewall than my router for a lot of years, and I don't have any virus/spyware issues here. It helps not to visit questionable sites, keep your AV and spyware protection up to date, and just know what's going on in the world.

When is an NAT Router Inadequate Protection?

Nothing I see there changes my mind. FWIW, most newer routers have SPI, which is one of their issues. I wouldn't let AOL within a country mile of my machine, so that's not an issue! I also have more than sufficient backups, including off-line backups.

I didn't post it to change your mind. After all, there are several people that visit this forum and I posted for everyone's benefit - not just to say you were wrong.

In fact, i'm not saying you're wrong. My only point is that NAT should not be relied on as your sole/primary source of firewall as it is susceptible to IP spoofing attacks among other weaknesses.

Sometimes, one size does not fit all. The NAT should be just one element of a multi-layered approach to security - which is why that article suggest augmenting it with a software firewall.
