Lately (new router), unless I have a toon of mine repeatedly send "." to a UCS chat channel, that toon will eventually lose its "connection" to the UCS within 2-3 minutes every time I zone. Please fix your chat servers to send continual internal keepalive packets so people's routers won't forget the UDP connections.
This would be an amazing improvement when I log in from work! Firewall doesn't like uchat UDP connection
