Fellowship jabber: got firewall?
For those of you sitting behind firewalls or proxies that block connections to the standard jabber/XMPP ports, the Fellowship jabber server now accepts connections also on ports 80 and 443.
To use this feature, just configure your jabber client to use port 80 or 443 instead of the standard port 5222, leaving all other settings unchanged.
Note: since some ISPs may block outgoing non-http traffic on port 80, port 443 is more likely to work. In both cases, the server enforces a secure TLS connection.
