What is an open proxy G-line for?

You probably came to this FAQ because you got something like this when you tried to connect to QuakeNet:

Connecting to some.server.quakenet.org:6667
You are banned from connecting to this server ("Open Proxy. See
http://www.quakenet.org/openproxies.html. - ID: 666")
Closing Link: nick[IP.or.hostname.com] by some.server.quakenet.org (G-Lined)


You are running some sort of Proxy, probably Wingate or similar. This Proxy is misconfigured. It does not only allow clients on your LAN to use it, but everyone on the Internet, without any Authentication. Such Proxies are frequently abused by flooders. This is why every client connecting to QuakeNet is scanned for an open Proxy, and G-Lined (Banned) when one is found.

To fix this, reconfigure your Proxy so that it is secure.

The G-Line will expire after 30 minutes. If your Proxy is secure, you should be able to reconnect after 30 minutes. If it isn't, you'll be banned again.

We are currently scanning a number of common proxy ports. So if you get G-Lined you have an open proxy listening on one or more of these ports.

How To Fix The Most Common Proxies

Wingate: See this page.

Sygate: According to Sybergen, updating to the latest version fixes the open Proxy

Netproxy: Check this. Configure it so that it rejects all connections except the ones coming from your LAN

Winroute: This by default has Webproxy enabled and configured incorrectly. Configure it properly or just disable the Webproxy.

As a general rule for Proxy-Implementations not listed here: Configure the proxy so that it refuses to work for clients outside your LAN, or even better: Set it so that it only binds to your LAN-Interface. Alternatively you need only ensure that users cannot connect with an "anonymous" (or NULL) username/password (which is normally the default setting with proxies).
