What type of NAT/PAT appliance/route is doing the translation?
NAT/Cisco PIX
What are the default socket timeouts?
Couldn´t get this info, not shure really where to look
Your netstat(8) should have a "state"colum to tell you what the 3-Way-handshake
state of your sockets is:
Yes, the state is ESTABLISHED, and stays like this for several minuts
# netstat -an | grep client-ip
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 server-ip:110 client-ip:4642 ESTABLISHED
tcp 0 0 server-ip:110 client-ip:4638 ESTABLISHED
tcp 0 0 server-ip:110 client-ip:4630 ESTABLISHED
tcp 0 0 server-ip:110 client-ip:4626 ESTABLISHED

What type of NAT/PAT appliance/route is doing the translation? What are the
default socket timeouts? Its likely not transmitting RST packets properly,
and/or keeping bad states.
