[SR-Users] TCP Keepalive for NAT'd Clients

[Colin Morelli]

Hey all,

Looking to figure out the best way to allow TCP connections to stay alive
for NAT'd clients, however, to protect against people just opening TCP
connections to the server, I'm hoping to only keepalive TCP connections for
connections that have sent an INVITE and received a 200 OK.

Does this type of per-socket connection lifetime setting exist?

For a bit more background: this is specifically for clients that are using
the TCP connection for an INVITE. They don't register with the server, and
as a result there's no active flow timer for their connection. Is there a
way to enable this type of behavior without registering?

Best,
Colin
