You can generate keepalive packets for every TCP connection between your FreeBSD box and the world using ipfw. A rule like: allow tcp from any to any keep-state will effectively keep all TCP connections alive. Two things: 1) If you are not familiar with ipfw, read the manual before loading the ipfw module. Otherwise, you'll be locked out of your box. 2) I don't know if the above rules fits your security policy. Or the services your FreeBSD box provides. Modify as needed. HTH, Nikos
