Re: remote vpn disconnect automatically ???

Please disable all of the isakmp keepalives which can help if the disconnect due to loss of DPD packets.

If that does not help then try to enable idle timeout to unlimited. To do this, make the vpn-idle-timeout to none on the group-policy attributes

Finally, make sure all clients the DPD setting is set to maximum which is 480 seconds. There is a configuarable peer response timeout which is defaulted to 90 seconds. To adjust the setting, enter the number of seconds in the Peer response timeout field.

The VPN Client continues to send DPD requests every 5 seconds, until it reaches the number

of seconds specified by the Peer response timeout value.
