We have the servers inside our network that the employees can Telnet on. The session never time out.
We have a regional office from where the employees Telnet on the same servers but they have a timeout after 10 minutes idle time.
All the network devices are Cisco. The regional office is connected to headoffice via a VPN connection. The VPN is terminated on my Cisco Firewall.
Would somebody have any idea what the problem can be?
I am wondering if I have to change any configuration on my Cisco routers or switch or even firewall!!! but I do not know what it is!!!
the firewall (assuming ASA) will typically have an idle connection timeout. The default is an hour whereas you are reporting 10 minutes.
timeout conn 1:00:00 half-closed 0:10:00 udp 0:02:00 icmp 0:00:02
