Port forwards not working

I have a client that I just installed a new custom built PC based DVR for.

I can get the remote viewing to work locally so everything including the software firewall are configured correctly.

However I am unable to get the remote viewing to work outside the store. I have checked and double, and triple checked the port forward configurations. There are not overlaps, mismatches and all go to the correct IP address, the DVR has the correct static IP address.

I have rebooted the router numerous times by adding reset.htm at the end of the address, I have also rebooted it at least twice by unplugging it.

I have had this trouble with this router before, but mysteriously it started working.

I was hoping that a firmware upgrade would resolve the issue, however their are no firmware versions available even past versions.

The model of router in question is a Linksys WRT54G version 5.

Any one have any suggestions?

Get a new router??? That's like a dinosaur in terms of a router. But....

Have you used CanYouSeeMe.org to check to see that individual ports are indeed open from an outside perspective on that computer?

You don't have some kind of double-NAT going on with router behind a router? Like the ISP's router/gateway and then the Linksys behind that.

Try setting the computer as the DMZ host. If that makes it work from outside, you KNOW it has something to do with the port forwarding issues.

Thanks goombawaho
I would have replaced this router a long time ago but some clients don't want to replace something when it is working just fine. Wireless is not used that much at this location.

Looks like I am going to have to replace it now as it won't work with the IP address in the DMZ.

When someone tells you this, say the following:
"I haven't been to the doctor in years and I'm feeling just fine." Same principle.

Could plug the computer into the modem directly, bypassing the router. Then turn the firewall off on the PC and see if the port is open?
