ENet does its own keepalive stuff, I'm pretty sure. Forgive me if I'm mistaken, but you didn't explicitly say that you were calling enet_host_service() on the client regularily; could that be the problem?<br><br><div><span class="gmail_quote">

Host, the client is disconnected after approximately 30 seconds. We have
traced this on the host side to a call to <span style="background: yellow none repeat scroll 0% 50%; -moz-background-clip: -moz-initial; -moz-background-origin: -moz-initial; -moz-background-inline-policy: -moz-initial;">

enet_peer_ping(…) that is on a timer to fire every 2 seconds – but the
disconnect still occurs. The host runs a perpetual loop that calls
enet_host_service(…).</span></font></p>

<p><font face="Arial" size="1"><span style="font-size: 9pt; font-family: Arial;">One thing I noticed from the Cube Legends source is that
they added a PING / PONG message so that whenever a PING
message is received on the server, it immediately does an enet_peer_send of a
PONG message back to the client. Are there other and better ways to
handle "keep-alive" packets?</span></font></p>
