It could be that your ISP is blocking the port. No way to get around that, other than to use a different port.

This may sound like a silly question, but have you verified that the destination computer's IP address is actually 192.168.1.101 (Linksys DHCP starts with .100 by default) and that the port is open on the Windows (or other software) firewall on the computer? It's entirely possible that the router is forwarding the port exactly as you instructed it to, but it's not going to the right computer on your network or it's being blocked by a software firewall.

Second, is your ISP's "modem" a simple pass-through device or does it have its own internal NAT firewall/router? If the ISP device is a router, you'll need to forward the port from the modem to your Linksys router's WAN IP address, and then from the Linksys router to your computer's IP address.

Also, as drebo mentioned, your ISP could be blocking the traffic, and not just that port but P2P traffic in general. If this is the case, there's really not much you can do about it except try another port.

Yes, if you had looked at the Hardwarecentral link, you'd see that I have the IP on the machine in question is set to static. Also this is the network from where I work where we use the exact same ISP and service as I do at home and with my Belkin router I have no problems. This problem does however exist on another friend's machine with the same IP and same Linksys router.; Whatever the problem it is specific to the router, but I'll be damned if I can figure it out.

Oh and the ISP is cable and it's just a modem, no router.

How is your linksys router connected at work? Is it directly from modem to router?

Well I did forget to mention that at work it goes, cable modem, router, switch, then to me. As far as using a non standard firmware, that works for all of the WRT54G's except for the v5. I will never pay for a linksys product.

There thousands of people that use Linksys Router and have No problems.

My observation shows that in situation that it seem Not to work.

20% encounter a specific device that is RMA grade.

80% do something wrong and they are unaware of it.

P.S. The above is True for most mainstream Network Devices.

Linksys routers have been the best consumer grade products I've used to date. I've used several of their wireless units and now currently use the rvs4000 with good service through my hp procurve switch.

Edit: The rvs-4000 is no longer with me and currently resides in the compusa return bin. It started slowing down my internet and then refused to allow any ftp access. Today I replaced it with a d-link dgl-4500 and all is well again. Up until this router I was pretty satisfied with my previous linksys units.

I have to contest this notion.

It is kind of Technical/Intellectual laziness to assume that there is a Brand that all their devices are Good, and others, that all their devices are bad.

Each Brand has Good, Mediocre and bad models, and that includes Linksys (Actually Linksys has more than its fair share in Mediocre and bellow Devices).

The WRT-54g v5 is a mediocre and bellow device, but port forwarding is not its problem.

So your network setup right now is Cable modem - Router - Switch - Linksys WRT54G?

Assuming the above, I'd suspect your work is blocking that port (as well as most others). Unless your are the network admin, you probably will never get this working. To completely rule out the linksys being the problem, take it home and set it up in your home network in place of your Belkin router.

No, it's cable modem > Linksys WRT54G v5 > switch > me....

I am the network admin (any of us who work there have admin rights). Three people work at the shop. It is not blocked. As well my friend has the same ISP and the same router and I can't make it work for him either. His is just: cable modem > router > his PC. I know how to forward a port, and as I have said this is the only router I have ever had this problem with.

Oh and I repeat, I have the same ISP at home and a Belkin router and I get 10mbps service and it works fine here.

It could be any number of things, but most stuff like this is user/configuration error. You're using process of elimination to troubleshoot, can't do that with networking - you need to see and understand what is happening.

Download wireshark to see what is really going on. Get packet captures on the WAN and LAN side of your router.

If you are being paid to work on this, it'd be cheaper to just buy a different router rather than spending more time troubleshooting this. Most employees have a true cost of $50 to $100 an hour, meaning that you could easily buy a new router rather than spend an hour more troubleshooting.

Test if port forwarding works in general by seeing if you can forward RDP (TCP 3389).

Does your cable modem put you on a private subnet behind its own firewall? I have personally seen a couple Comcast modems that have multiple LAN ports and do NAT. If this is your case, you need configure port fwding on your modem as well. How is your Linksys' WAN port configured? Does it get a public IP?
