I can never connect.

The firewall is being a little oversensitive. We had the same issue a while back. It does help protect against DDoS attacks, but it blocks a lot of legitimate access to the website too.

Currently, we allow people to submit their IPs to be unblocked via http://www.sythe.org/ip.php - So please use that! You can contact other people to do this on your behalf. In the mean time, just be careful about proxies you use - You are responsible for your account and should be careful.

Apologies on behalf of site management for any trouble you're having.
