Timeout for remote user coming through a VPN tunnel on a Cisco Pix 515e

A remote user's connection times out after about 30-90 minutes when coming through a VPN tunnel from a remote site. I have two Cico 515e pixs acting as peers. These are the timeout paramaters:

timeout xlate 3:00:00
timeout conn 1:00:00 half-closed 0:10:00 udp 0:02:00 rpc 0:10:00 h225 1:00:00
timeout h323 0:05:00 mgcp 0:05:00 sip 0:30:00 sip_media 0:02:00
timeout uauth 0:05:00 absolute

It is my understanding that these do not apply to the VPN tunnel (or do they?) because the firewall will see the remote tunnel as a local connection and treat it like it is on the local LAN.

Hi truelove258,
The Cisco client has an option to enable keep-alive which is on by default and this will stop the VPN connection from timing out.
The timeout parameters I would expect would apply to traffic terminating on the VPN end point PIX. The reason why I say this is because the PIX does need to track the connection in order to enable back the replies from the servers. Normal TCP connections have a timeout of 1 hour and UDP has a timeout of 2 minutes.
