Fix Cisco VPN dropping on mobile:
Server configuration:
Enable NAT Keepalive (send periodic packets to keep connection alive)
Enable IKE Keepalives (verify connection with IKE protocol messages)
Increase User Idle Timeout (prevent server from terminating inactive sessions)
Mobile device settings:
Check power saving settings (may disconnect Wi-Fi/data)
Check VPN client settings (disable options that disconnect VPN when idle)
Consult Cisco documentation or support for further assistance.
