There are a number of tunable socket parameters that can be modified via FWCONFIG file
tcp_keepalive_time - Connection Idle Time in seconds before socket starts sending keep-alive messages.
tcp_keepalive_intvl - Time in seconds between keep-alive messages.
tcp_keepalive_probes - Number of (lost) keep-alive messages before connection is considered as dropped and socket is disconnected .
Keep-alive Timeout (secs) = tcp_keepalive_time + tcp_keepalive_intvl * tcp_keepalive_probes.
Example:
ipaddressmask dhcp sleep 20 tcp_keepalive_time=2 tcp_keepalive_intvl=1 tcp_keepalive_probes=3

|
tcp_keepalive_time, tcp_keepalive_intvl and tcp_keepalive_probes are global and will affect all TCP/IP sockets. |
