NAT Question (Azureus Client) [SOLVED]

kompressor · Last edited by kompressor on Fri Dec 23, 2005 12:53 am; edited 1 time in total

Heres the deal,
I emerged azureus bit torrent client, and It says NAT error on port 6881. ( tried other ports, same result)

I am behind a router, I did add this machine to the port forwarding list.
Could it be a setting in linux somewhere? I dont have this problem with my windows setup.

Any ideas are appreciated.

Are you running a firewall like iptables? You'd have to forward the port on your firewall as well.

That is a good point. I do have iptables installed, but I' havent ever used it before. is there a way to see if iptables is enabled? or currently active

/dev/random · Posted: Tue Oct 25, 2005 12:20 am Post subject:

/etc/init.d/iptables status

says stopped.

It is possible to have it running without the init script being start so also run iptables -L and post the output here.

I am having the same problem with the NAT error when running Azureus Up till a few days ago it worked perfectly under user. Azureus does work find when i run it under root though. I dont have iptables and never had.

Azureus says the tracker status is "Scrape OK" and it sees that there are 55 seeds and 743 peers, but it hasn't connected to any of them. Tested it with another torrent and same situation except tracker status is "OK"

If anyone can help I would very grateful. Thanks in advance.

Here are my processes (Azureus turned off):

Do you guys use the Azureus ebuild? I have it installed in my home folder using the gtk tarball from azureus.sf.net perhaps that would make a difference.

# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

I did use the ebuild.

I got the same error and I am using the ebuild with tor and privoxy as stated on: https://forums.gentoo.org/viewtopic-t-269815.html

I am behind a NAT router that forwards the tor, privoxy and azureus ports (8118, 9050, 6118). I still get the NAT errors...

I fixed my NAT issue.

I learned that I was misconfiguring my router.
I had the same ports forwarded to different machines.

so I just pointed a different range to the other machine, and told azureus to use one of those. and it went green.
changing post to solved.

I spoke to D-link, since I have a DI-604, and they finally said, after 7 calls, that the router can't handle that work load of azureus. Azureus is based on java and sucks the power of the system and the router. This guy recomended the bittorrent clone ABC that only uses one port and less resources.

I guess I'm outta luck when it comes to router and Azureus. Perhaps I should build a router of my own... only it would eat much more electricity. Tuff one.

I'm aware of the advantages of using one port, ABC does the same.

I haven't looked in to what goes wrong with the router since it crashes as soon as I start Azureus resulting in total loss of the logg. I worked with the D-Link tech support, switching ports etc., and they finally asked me to send in the router. D-Link kept that one, stating that they couldn't repair it (...!), and send me a new one to try. Same thing with the new D-Link router so they got a new explanation: Azureus demands too much from the D-Link router resulting in a crash.

So here I am with a D-Link router that crashes and no support available except the recomendation of using ABC.

Hi all

I have a safecom 54108 wireless router and there's something crashing it and I have a suspicion that it's azureus. It has crashed twice within the last 3 days, the first day I was using azureus-2.3.0.6-r1 with a few downloads on the go. I could not get communication with the router until I turned it off and restarted net.eth0. The next time I was trying btdownloadcurses.py in a gnu screen environment following this thread https://forums.gentoo.org/viewtopic-t-219742-highlight-azureus+stops.html which went quite well but then I opened azureus and restarted 2 downloads there as well and a few hours later the router crashed again.

I am now trying btdownloadcurses.py in a screen environment again and we will see if this does ok. I am afraid I know very little about the router settings and am afraid to touch these.

Late reply but I think Azureus could cause the problem (due to the D-Link respons). According to the D-Link tech support, it could also be that the throughput, using bittorrent clients, is too large for your router. My problem came back, somewhat less, with bittorrent instead of azureus.

Check the throughput and call the tech support and see what they say.

I don't think my solution will work for wireless. I just took an old pc, put smoothwall on it and used the D-Link as a switch by not plugging in the WAN cable to the WAN port. Instead I plugged it on the LAN side and disabled the dhcp server. Also smoothie is transparrent on all tests I've done, something I couldn't achieve with the D-Link router!
