Port Blocking P2P

pallys · 11-04-2004, 01:39

Hi, just wanted to know if NTL implement port blocking ?
this is because for those who are familiar with emule default port 4662 was used and now its blocked and I cannot connect to a emule server with hgh-id
Reading its help files it says your ISP may port block this and so they have a feature where in options you can change its port number - and upon reconnecting if u get a high-id it means that your ISP was blocking the default emule port.

Anybody else experiance this ?

Regards.

NTL do not block port 4662.

There is a small list of ports they do block - off the top of my head I think it is 135, 137, 138, 139, 445 & 1433. I'm sure there are a couple of others as well.

One other thing to note if you have a transparent cache in the proxy server settings.

Also well if your using bit torrent and your behind a firewall remember it need ports 6881-9 open

Another thing to check with XP is make sure the XP built in chocolate teapot of a firewall is not on.

Some good info on port blocking can also be found here and here

what firewall if any do u have or router?

donkeys diff to setup anyway at the best of times. i'd recommend using the ftp port for a start(21)for all ure incoming quieries and udp 4672.always had a decent conn on these and would recommend them to try before giving up. this is not a proggy like kazza, it take a little time to tweak and get those all important conns with. if you need any extra help with it drop a line

Hi, thanks for the replies
I use Zonealrm as firewall and no router, and have given emule access to all prts and protocols.
Problem is with port 4662 it does not give me a low rating and a message that it cannot get to that port - everything used to be fine onthis port and I havent changed a thing whicbh is mysterirous. So I read its help files and changed it to another port, 4661 or any other, and all is fine again, only this reason I wondered if NTL had begun to block port emule's known default port of 4662 because I was forced to change it

TBH, Zonealarm is more likely to be the problem than NTL. Try removing all references to eMule in it and starting again.

Also, make sure nothing else on your system is using port 4662.

Turn your firewall down to "medium" for the internet.

Hi, I removed Zonealarm from running (XP firewall also disbaled) - still same problem .
the only way I can think of is if other people here on NTL who use emule can connect to servers on port 4662 - if they can then there must be some weird problem on my machine.

Regards.

how do u connect to the web? connected straight to the modem through nic or usb?

They are kicking you because you are "known" for being difficult to connect to because of ZoneAlarm - use ZA on medium, leave the program running for a few hours each day and you'll be fine.
You will also get a high ID if you don't run the program for very long or upload much.

@ richard m - are u confusing ID with the inbuilt credit system?

The purpose of the ID system is to give you an idea if ur ports are working correctly (eg open) and if u can chat to other servers and other clients.

Richard M · 12-04-2004, 13:21

Yeah I know that but IIRC, uploading or connecting for a long time will give you a low ID.

SOSAGES · 12-04-2004, 13:36

uploading or connecting for a long time have nowt to do with your id i belive - you ability to chat to servers and clients dosnt falter the longer your connected or the more u upload - the idea of donkey2000 network is u stay connected for a long time so getting worse over time would be a bad idea .
