I need to get Zywall/USG/ATP/VPN to answer pings on the WAN side. How to allow PING on WAN?
There is a default firewall rule - WAN_to_Device, with a default allowed service group object - Default_Allow_WAN_To_ZyWALL. You need to add PING to this service object group.
- Login in to Web GUI on the device
Go to Configuration > Object > Service > Service Group tab
- Click the "Default_Allow_WAN_To_ZyWALL" service group object to change it
- From the left menu, select PING, then click the right arrow to go to the right menu and click "OK"
- Now you can try to PING your WAN Ip-Address
