Hi Folks,
I have an ASA with several LAN to LAN IPSEC tunnels configured and having VPN drop outs if we leave our session idle for sometimes as little as 5 minutes.
Can this be increased to something more realistic, say 60 minutes +?
Thanks,

Do you have crypto isakmp keepalives configured?
Also what is the idle time currently configured for phase 1 and phase 2?

Can you please post the output of the following:
show run crypto
show crypto protocol statistics ipsec
show crypto map detail
Also what values have you used in the crypto isakmp keepalive command?
Is there any firewall in the transit path?

Also I forgot the most important command
show run all group-policy
I'm just looking for the
vpn-idle-timeout and vpn-session-timeout commands in there. They are used to set the idle/absole timeouts for VPN connections. You can increase them and check.

Please configure the following and test:
group-policy DfltGrpPolicy attributes
vpn-idle-timeout none
Or set it to something higher? Default is 30 minutes of idle time.
