ssh through a masq box - connection reset by peer

Anybody out there have a good solution to the connection reset by peer
issues when using openssh through a masquerading host?

Using openssh 2.2 and have KeepAlive set to yes on both client and server
side. Have also changed value of /proc/sys/net/ipv4/tcp_keepalive_time to
300 and 120 with no luck.

Anybody out there found a way to resolve this? I'm opening six windows at
a time and they're timing out and closing before I get back to some of
them. Really annoying when you're in the middle of things.

Thanks :)
