tcp keepalive?

[Daniel Nielsen]

Hi.

I'm behind a NAT (over which I have no control), And it seems to kill idle tcp 
connections quite fast. Is there anyway to make freeBSD 5.1 send tcp 
keepalives with smaller intervals?

It was possible in linux with sysctl net/ipv4/tcp_keepalive_time=300...
In freeBSD I have not been able to locate the equivalent option. Any help is 
appreciated.
