Port forwarding

[shingy]

Hello everyone. I am having an unbelievably hard time getting my router to forward a couple ports (specifically for Skype). I have been doing this for years and have never had this much trouble. I have tried two different routers, two different computers, and connecting via wired LAN and wireless. I have also tried updating the firmware on the routers with no luck. I know how to correctly set port forwarding, so I am thinking it has to be something else.

Here is my info:
* I am running Windows XP SP3 on both computers
* The two routers are: Linksys BEFW11S4 & Netgear WGR614

I recently upgraded to SP3, but I changed routers at the same time. Could something with SP3 be causing this? Any help you could give would be much appreciated.

Thanks,
Jason

Have you been to
http://portforward.com/
and looked for any guides for what your trying to do?
Is your firewall cooperating?
Settings correct?
Turned off temporarily to see if it helps?

Yea, i've been to portforward.com to double check my router settings just in case I overlooked something. The only firewall I have is the one integrated into windows and I have turned that off.

Go to ShieldsUp and run a port scan on the ports in question, post the results here.

Ok, I ran the ShieldsUp scan.. a picture of the results page is attached below.

It appears they're not actually forwarded through the router correctly.

I think we need a screen shot of the port forwarding settings, as well as an IPCONFIG /ALL from the machine in question.


To post a screen shot of the active window, hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file. To upload it to TSG, open the full reply window and use the Manage Attachments button to upload it here.

Thanks for the quick replies, John.

Here you go.

So, what do you guys think?

 

[JohnWill]

Well, port 80 and 443 may well be blocked by your ISP, many ISPs block incoming traffic on those ports. OTOH, the high numbered ports should work, that setup looks correct.

What is in front of this router, exact make/model of the modem?

 

[shingy]

yea, I figure that 80 and 443 are blocked, but my real interest is with the other two.

I have a DSL modem through AT&T:
Make - Westell
Model - C90-610030-06

 

[JohnWill]

The DSL "modem" is a modem/router, so you'll have to configure it in bridge mode, put the Linksys in the DMZ of the Westell, or consider using the routing function of the Westell and configuring the Linksys as a wireless AP.

I enabled DMZ (called "IP Passthrough" here), but couldn't find anything referring to "bridge mode". And, still no luck with the forwarding.

Please tell me exactly what settings I need to change and what they should be set to.

Thank you very much for your help.

Thanks for the link, John - it was very helpful. I'm finally getting somewhere, but not quite there yet.

I enabled the bridge mode on the modem and set my router up for PPPoE. Using the ShieldsUP port scanner, I showed that the Skype port (51550), 80, and 443 are all open. However the other port (62805) still shows closed. I also tried setting my computer to the DMZ host and still showed as closed.

What do I have to do next to get this fully working?

Thanks again for all your help.

The closed port is indicating that it's making it through the router, but the application is not responding.
