HOW DO I RESOLVE A NAT PROBLEM

HI

 I HAVE A COX CABLE MODEM INTERNET CONNECTION, AND I HAVE A NAT PROBLEM, THATS FOR SURE BUT CAN ANYONE HELP ME TO RESOLVE IT. I DID GET SOME LINKS FOR IT, BUT ALL OF THEM EXPLAIN THE RESOLUTION IN CASE OF A ROUTER. BUT I DONT HAVE A ROUTER I AM DIRECTLY CONNECTED TO THE CABLE MODEM. I DID TRY TO USE A STATIC IP ADDRESS BUT THAT DID NOT RESOLVE THE ISSUE.



THANX

What type of NAT problem?  Please provide some more details.  Is your Internet down, are certain ports blocked, etc?  Some modems send out NATed IPs when there is no Internet connection.  Provide info please.

ok the deal is i am using 64512 port to download using azureus , how i found out i had a nat prob is by this https://www.grc.com/x/portprobe=64512
i have changed the port numbers tried many but its the same with all the ports. so i think that may be certainports are blocked or something but how do i set this thing straight

thanx
Ashwin,

Are you saying that you are unable to download files with Azureus?  If so, you probably need to forward that port to your machine on your LAN.  To do so, access the router's config page by typing your gateway into the web browser.  Access the Port Forwarding section, choose the port you want opened, and point it to the LAN IP of your machine.  Give that a shot.

hey thats wat the prob i am having i dont have a router i am directly connected to the cable modem, so how do i set the port forwarding in the modem.
There is more than likely no port forwarding in the modem.  Instead do this.  Go to Start-> Run ->type in cmd -> hit enter.  Type in ipconfig and his enter.  Copy and paste the output here.

Agree..  Unless your PC is getting a Private IP Address from your modem, then NAT (or PAT in this case) is not the issue here, as it does not come into play..  The technical way to resolve this would be to place a packet sniffer on the wire coming from your modem to your PC to see if the packets are actually getting through the modem at all...  If they are, then the problem rests with your PC, and if not, then it is more likely your ISP that is blocking this traffic..

One word of caution...........

I have a friend who is on Cox and he just recieved an email form Cox sent on behalf of one of the large media conclomerates. ( the guys that make and own the rights to movies ad DVD's) In essence the media company has been monitoring ad tracking File Sharing via Azureus, Bit Comet etc. They  determined that he was downloadong copyrighted material they forwarded the logs with the file(s) the time the date his IP address. Cox stated that he had X number of days ( something like 3-5)  to delete all the copyrighted materail listed AND prove that he had removed it or his internet access would be shut down.

AS for what the issue is.............. either Windows XP Firewall, ZoneAlarm or some other firewall software you are using is blocking itis blocking the port. OR COX HAS BLOCKKED IT.  If it is the later then you are out of luck. I don't know of any specific instance of them doing this at this time. However the email my friend recived was delivered to him Juy 21st 2006.

Hope that helps
