<DIV><SPAN class=512540615-02042003><FONT size=2>We have a good and solid VPN
between a Checkpoint and a NetScreen, its up and solid. I can send 100 pings and
get 100% response. Ping times across the tunnel are 63ms average. The
developers for each company keep saying that the "firewall" is dropping the
packets. And it is. Application A starts the session(syn), App B
answers(synack), App A(ack)....no problem. The apps even talks out to the
correct DST ports. Problem comes when App A tries to send info over the
established session (example src port 2565) but sends it out 65 seconds since
the last communications, the firewalls time out the session and App A should
resend over a new source port. It never does. It will try till its dying days to
communicate over that FIRST session.</FONT></SPAN></DIV>

not a programmer, is there anything that I can do to lessen the problem from a
firewall/VPN point of view? I keep saying that they need to speed up response
times on their TCP communications and send "heartbeats". They call me
"Non-Helpful"</FONT></SPAN></DIV>
