[Linksys BEFSR41 v2] NAT not working even after port forwarding!

[wolf333]

I recently moved into a university apartment with a cable modem (whois identifies the WAN IP as belonging to Merit Network and Michigan State University). My roommate already had wired router, a Linksys BEFSR41 v2, set up for a LAN.

I am trying to get uTorrent 1.6.1 to work on it, but I am having problems. I upgraded the firmware to the lastest version and I followed the PortForward directions, found here:

http://portforward.com/english/routers/port_forwarding/Linksys/BEFSR41v2/Utorrent.htm

But still no luck! I have searched around for relevant info, but since the router is so old it's all from 2002-2004, and usually refers to BitTornado or other clients, so it's not been any help.

At home, before I moved, I was connectable, which leads me to believe that the problem is with the router or with the ISP.

Being poor college students, we would prefer not to have to buy a whole new router to get uTorrent to work, so any help is greatly appreciated!

So, what could it be?

Thanks!

Hi, You are most likely behind the University's Router so do this to check your IP in the router:

#1 Status -> Router.

What is the first two octets of the Internet IP Address there? For example if your IP was 70.110.100.100, then your answer would be 70.110.

The first two octets are 35.11.

OK that seems OK What is the make & model of the Cable Modem?? Can you post a screenshot of the Port forward Page of your Router

[wolf333]

Here's my port forward page:

My cable modem is a Motorola SB5100 Surfboard.

Did you assign the Static IP Outside the range of the DHCP?? Read this guide on How to Choose a Static IP:

Also the SurfBoard Modem can also be a Problem so Read this Guide on that issue:

Well, the SurfBoard doesn't seem to be doing anything based on the link you posted.

I hadn't assigned a static IP address yet; I just did it, but the port still doesn't forward properly (and yes, I did remember to change the IP in the port forward settings on the router).

PS: Thanks for the help thus far!

The SurfBoard doesn't need to be behaving exactly as the link says; I've seen many cases where, even though your computer's IP address isn't an internal LAN IP, it still has problems with forwarding connections to your computer. That's why, at this point, I don't bother linking to the post anymore. It's easier to just tell people that SurfBoards are stupid (lol, because they are xD).

[wolf333]

Are there any possible work-arounds to it then?

[The_Nephilim]

Yes If allowwed by your ISP get another Modem. but then your ISP will Probally not offer any Support in setting it up. Your Other solution is to get a new ISP.
