I have a single machine connected to the Internet through a DSL-W 906E Single-Port ADSL Router which hardware browser shows as a Realtek RTL-8029(AS) with the following spec:

* Network address translation (NAT)
* Integrated ADSL modem – 1 x RJ11 connection
* 1 x 10/100Base-T RJ45 switched LAN port
* NAT based firewall
* Integrated DHCP server
* Port redirection
* Remote configuration via Telnet

Fedora Core 2 automatically set it up using DHCP.
The Azureus test on port 6881 gives NAT error. I understand this error is to do with port forwarding, but I'm not clear what this involves - which port to where - or how this is setup.

Azureus always shows the yellow symbol implying I have a NAT problem.
I've googled, but did not find anything that matched my particular setup. I do hope someone will be able to offer help
Thanks

It seems likely that the issue is with the DSL-W 906E firewall/NAT setup and not with Linux. IF your ISP sets it up (remote config) as is the case with many of the larger nationally advertised ISPs, you may be out of luck.

Check out http://azureus.sourceforge.net/wiki/...PortForwarding for more info.

Thanks for that. I had this router before I discovered Linux and set it up using the program on the accompanying CD. It wasn't configured by my ISP. The documentation shows how to configure it via telnet, but doesn't cover port forwarding.

the commands I've dared to try show the following config:

[john@localhost john]$ telnet 192.168.1.1
Trying 192.168.1.1...

The routers I have seen on the azureus help pages can be accessed via a web browser. This router won't accept a connection that way, so the only option appears to be telnet. I am afraid to experiment which might leave me with no internet connection at all,and would appreciate advice.
Thanks so much.
