[FW1] NAT: Telnet timeout question

[Rick Tortorella <RTORTORE@mobius.com>]

I have a problem with a NATed user (hide mode) who sets up a telnet
connection.  He connects fine but after an hour or so of inactivity the
connection is dropped.  I'm pretty sure that it's the site that he's
connecting to that is dropping him after a specified period of inactivity
but that brought up a question concerning how NAT works on a FW-1 box.   

I've read the rfc's for NAT and I've read the info. that comes with FW-1
(not very descriptive).  I wanted to know how FW-1 dynamically assigns ports
to NATed IPs (technical detail) and how long those sessions stay open in the
active state table.

Any information, links, etc. would be appreciated.

Thanks.
