In the help think in playing games i tried to fix it so i could host...but now i cant play byond games and the hub or pager wont open! How do I fix this, by the way i wrote client/authenticate = 0 into the pink bar
Here's what it said to do:

Login Trouble
On the Internet
If you cannot log in to games hosted elsewhere on the Internet, you might be behind a firewall that doesn't even allow full access from your network to other sites. (That's different from a firewall that doesn't allow full access to your network from the outside.)

BYOND games run on a variety of network ports, so there is no simple configuration that will make such a firewall allow access to outside BYOND games, short of disabling the filtering of connections from the inside to the outside.

If you are unwilling to do that, you may just have to enable access to specific games that people are hosting on fixed ports. In that case, you would also need to enable access to BYOND Hub. This takes place through the web at http://www.byond.com and https://secure.dantom.com. DreamSeeker also requires access to port 6001 at dantom.com.

In a LAN
Another source of trouble happens when logging into games hosted between machines on an internal LAN with no direct connection to the Internet (the ultimate firewall). Normally, BYOND Hub is involved in the authentication process, in order to securely verify the global identity of users. When you are on an isolated LAN, the hub is not accessible, so this will fail.

To fix that, you can disable hub authentication. This can be done by compiling games with client/authenticate = 0, or booting up DreamSeeker and entering the command .configure hub-address none. In either case, users will be allowed into the game without any certificate of identity from the hub. Note that this configuration setting must be made on the machine hosting the game. Whether the other player machines do it or not is irrelevant.

Of course, users must still somehow obtain a BYOND key. This could happen via a dial-up connection to the Internet, or the key could be installed on some other machine with Internet access and then the file Byond/users/windows-login/key.txt can be copied to a disk and manually installed elsewhere.
