First going to tell how my network is configured, I use my AT&T Gateway for just my modem and firewall, and I use a Netgear router as an wireless access point. I ran a full port scan and found that port 3479 is open, is it an possible security risk, and if it is what can I do about it?

Yes, that port is used as a Remote assistance port by AT&T. So, they could potentially use it as a back door into your network.

I would recommend closing it on the Gateway or blocking it on your Netgear. However, if you block it, some games such as Call of Duty won't work completely right.

I can't close it, I got the Gateway blocking all incoming connections which should mean it's closed, and I tried to block it on the Netgear also but it still appears as open when I do port scans.

This again. There is no backdoor on the 2-Wire/Pace gateway. I really wish this false rumor would just stop and go away.

Never going to happen, due to this supposed "Back door" is nothing more then a blank rumor. There is no open port for the techs to access on the RG's.

The next choice is blocking it in the firewall of each pc on your network.

Not exactly right. I used to work as a Network Security Admin at a university and using open ports as "back doors" was one of the first things we all learned to do and prevent in school. Trust me, if there is a way into a network or machine, somebody will find it and use it.

Either way, the OP is concerned about the open port and that is reason enough to close it in my opinion.

Explain why the port is open then if there's no backdoor

I got ​Windows
firewall turned on, pretty sure it's blocking most of everything besides the few programs I've allowed through.​

The port is not there for the Gateway. It is for CimTrak. See CimTrak - Wikipedia, the free encyclopedia It is mainly for file integrity monitoring & compliance. Who ever started this whole Backdoor on Pace Gateways, should be found and flogged.

Unless people understand what certain ports are for, and also how to read, along with interpret the information they are seeing, when running tests like GRC's Port scan. It is like going to your automotive mechanic's garage, hooking up their test equipment, not having a clue how to use it, and thinking that just because you see some error code, your vehicle is broke.

Again, there is no backdoor on the Pace Gateways. You do not use a Port as a Backdoor. ATT can access only the RG, just like Comcast can access their Gateways, to do stuff on them. But they do not have access to anything else attached to the Gateway.

A firewall only keeps the honest people out. In reality, it is nothing more then what a entrance door on a building is made to do. You lock it to keep people from just opening it and walking into the building. You can leave it unlocked, and anyone is able to open and close the door as they go in.

The supposed port on the Pace Gateways, started out as minor FUD, and now has turned into a full blown fire out of control. All in due to people keep spreading miss information about something that is not really there.

An open port on a hardware firewall is never good, unless intended on purpose by owner of said hardware (not any company), and the software running behind that port is known well and without any exploitable vulnerabilities.

Well, the Netgear also filters incoming traffic, so unless you have opened a port on it, nothing is going to get through to your machines at all without request. (Unless perhaps exploited with its own vulnerability - they have them believe it or not.) What that means is things you solicit, such as web browsing, and all other general usage works and things you did not solicit, will not.

Disable uPnP on Netgear for good measure.

So, it is secure in that aspect, but still - someone can access your AT&T without your permission. (Notably, likely ISP.)

You have to have open ports on the router, in order to have certain items work properly. If you were to close all available open ports, you would never be able to get onto the Internet, to browse websites, or retrieve files or email.

You can Stealth the port, and that is how it should be. You do also have to have ports open when running a File server, or a IP camera. When a request is made to that device, it should only go to that port, and access only what that port is mapped to on the device from the Router.

Think of port mapping, like following a road map across the country. Some exits may be open, others may be closed, while there are some that state on the map that they are there, but in reality are not. That is how the router works. It is told which ports to open and which to close, but should always be in Stealth mode.

That is why when people state that they did a port scan and found a bunch of open ports. The first thing that comes to mind, is why are they looking for open ports. The second is does the person understand the information they are looking at, from the results that the scan test gave.

There is no longer a "Bridge" mode for the Pace gateways. It is now DMZ Plus, which you use to allow devices full open access to the Internet.

If you are connected to the Internet, and worried about someone watching what you are doing, it is too late now. Regardless what people think that they can hide what they are doing, those days have gone away.

If you were to close all available open ports, you would never be able to get onto the Internet, to browse websites, or retrieve files or email.

Sorry, wrong. Doesn't work like that.

Uhm, yes it does. If you were to go into a router and shut down all ports, so nothing is able to get through the router firewall, you would get a dead request when the computer you are on, you are trying to browse a webpage, download email, etc.

Modern day firewalls on today's routers, use IPTables. They will Stealth the port, so that it does not show to outside ping requests, if it is open, but IPTables on the router knows whether it is open or closed.
