Router Port Forwarding Limitations


Working As Intended

-- Problem Solved, thanks! :D --

Hello everyone. :)

I couldn't find a thread related to this with the search function, so I apologize if I missed a pre-existing thread.

Here some general information first in case it's relevant.

Router: Linksys WRT54G 2.2
Router Firmware: v4.21.1
OS: Windows XP SP3

Problem: My family is relatively large and enjoys a large amount of computers & various gaming systems, primarily used by me and my brother. And due to our enjoyment of online games, things need to be port forwarded a lot. I know the general concept and mechanics of port forwarding, however I have come to what I believe is an annoying limitation. With our Linksys router (as with all Linksys routers, going by their Tech Support), we only have 10 spots to port forward. I know this isn't very descriptive, so here's an example picture from

(Assume the 10 spots you see in the image are the only 10 available in the Router settings)


I want to port forward WC3 for 4 computers - Which due to only being able to do one IP at a time takes up 4 spots, correct?

I also want both of my XBOX 360 to have an open NAT type for better connectivity, so I had to open the following:


After inserting those, my NAT was open and my router was no longer being stubborn. However, I need this for two Xboxs. So:

6 ports * 2 Xboxs + 1 port * 4 comps is > 10 (I ran out of spots, without even considering the Wii or other games). I tried to only open a few of the ports, but it was still a Strict NAT type, so I apparently need all 6.

My thoughts on possible solutions:

1) Open a range of ports for the Xbox 360s, 53 - 3330 to take up 1 spot per Xbox, instead of 6. However, would this compromise security or have any negative effects? Or would it not matter as much, because it's not a computer?

2) Find out if there’s a program that deals with my issue, allowing me to exceed the 10 spot limitation.

3) Change the opened ports every time I want to play each game specifically, and suffer with the huge inconvenience.

4) Use DMZ (De-Militarized Zone I believe) for the static IP of my XBOX 360s. I read a little it about this, but didn't like the concept.

5) Cry myself to sleep.

What are your thoughts? Know any solutions? Am I missing something extremely obvious? Any and all comments are welcomed and appreciated!

Get a D-link router. They have more slots than you know what to do with.
Thanks everyone for your posts. :)

I've downloaded and installed the program you suggested Samuraid, and it has provided the solution I was looking for.

I'll also be looking into Port Triggering in more depth for future reference, although at the moment I don't necessarily understand all the specifics of it.

It's also good to know that there are routers with more practical options available, instead of Linksys which made me get a 3rd-party program to get the desired results.

I am having troubles with the new Control Panel as far as my NAT not responding to the ports being opened. However that will be due to another setting being changed that I must have missed during the reset, which will be a simple matter of fooling around with some settings. It's working perfectly for allowing additional ports to be opened. There are also a lot of other added settings I'm looking forward to learning more about.

All in all I learned a fair bit in the last 10 hours, thanks everyone! :)

Mat, does the router software allow you to limit bandwidth per computer?
After looking through the web-based GUI and the software's Wiki, I couldn't exactly find anything about limiting bandwidth per computer. I did however find a Quality of Service page for prioritizing Services/Netmask/MAC/Ethernet Port.

Don't know if that has anything to do with what you're asking about, but it was disabled.

    News portal has been retired. Main page of site goes to Headline News forum now
  • The Helper The Helper:
    I am working on getting access to the old news portal under a different URL for those that would rather use that for news before we get a different news view.
  • Ghan Ghan:
    Easily done
  • The Helper The Helper: is a link to the old news portal - i will integrate it into the interface somewhere when i figure it out
  • Ghan Ghan:
    Need to try something
  • Ghan Ghan:
    Hopefully this won't cause problems.

  • Ghan Ghan:
    I have converted the Headline News forum to an Article type forum. It will now show the top 20 threads with more detail of each thread.
  • Ghan Ghan:
    See how we like that.
  • The Helper The Helper:
    I do not see a way to go past the 1st page of posts on the forum though
  • The Helper The Helper:
    It is OK though for the main page to open up on the forum in the view it was before. As long as the portal has its own URL so it can be viewed that way I do want to try it as a regular forum view for a while
  • Ghan Ghan:
    Yeah I'm not sure what the deal is with the pagination.
  • Ghan Ghan:
    It SHOULD be there so I think it might just be an artifact of having an older style.
  • Ghan Ghan:
    I switched it to a "Standard" article forum. This will show the thread list like normal, but the threads themselves will have the first post set up above the rest of the "comments"
  • The Helper The Helper:
    I don't really get that article forum but I think it is because I have never really seen it used on a multi post thread
  • Ghan Ghan:
    RpNation makes more use of it right now as an example:

    I will have to get used to this.
  • tom_mai78101 tom_mai78101:
    The latest news feed looks good
  • The Helper The Helper:
    I would like to see it again like Ghan had it the first time with pagination though - without the pagination that view will not work but with pagination it just might...
