 Posted: Wed Aug 09, 2006 12:16 pm Post subject: NAT Problem |
 |
|
Hi,
I tkink I've got NAT Problem - my azureus says.
Well, I did:
| Code: |
iptables -A INPUT -p tcp -i eth0 --dport 6681 -m state --state NEW -j ACCEPT |
and
| Code: | | iptables -A INPUT -p tcp --destination-port 6881:6999 -j ACCEPT |
and that
| Code: | | iptables -A OUTPUT -p tcp --source-port 6881:6999 -j ACCEPT |
After testing NAT in azureus it is still nothing.
I don't know what's going on..
P.S Iptables doesn't write any errors |

| These iptables rules may not contain errors, but they do not make sense either way. ACCEPT rules are incomplete and have an effect only if you're otherwise dropping them anyway. What you're looking for is probably port forwarding / DNAT. |

In the continuation of the previous post you probably need something like this
| Code: | iptables -t nat -A PREROUTING -i eth0 -p tcp -m tcp --dport 6681 -j DNAT --to-destination <machine_ip>:6681
iptables -t nat -A PREROUTING -i eth0 -p udp -m udp --dport 6681 -j DNAT --to-destination <machine_ip>:6681 |
<machine_ip> is obviously the ip of the machine running Azureus.
I tried to adapt the rest of the configuration to what you stated so it should work. I haven't used Azureus for a (long) while but as far as I remember it used to work correctly. |

Hmm, still nothing. Maybe we're working with wrong idea.
I think I didn't describe the situation.
My computer is connected to router and router is working with ADSL modem.
P.S I read Azureus Wiki and also tried to change the ports from 6681 to 52525 but that changed nothing. |

| It probably uses UPnP under XP. |

| Try to check if you can access that port from the internet on a site like grc shields up and if you can't then set up port forwarding on your router on a high port (those around 6889 can get blocked by your isp) and then test with grc shields up again. Oh and I think upnp is evil, especially under windows. |
