I am having a similar problem. I have some CentOS boxes serving SSH inside the
network, and I reach them from home across an older Fedora 3 gateway box. Some
variable time after I quit working for a while (perhaps around two minutes, but
sometimes much longer), the connection is lost. It has stunned me also, that when you are back at the keyboard, you can get some characters through before the connection shuts down. Would like to have it explained.
For timeouts, I did add "ServerAliveInterval xxx" in my /etc/ssh_config (client): That fixed my timeouts, but not my freezes...
