Question: What's the purpose of Auto disable VPN service?
Answer: This option means disabling UDP ports 500 and 4500 from WAN to ZyWall when no IPSec VPN rules are configured on your device. This option helps to prevent hackers from attacking your device through UDP 500 and 4500 when you're not using IPsec VPN.
