When adding vFW filter, NAT and NAPT rules, we can configure a target network as "Host - svxXXXXXXX LANX". Where can we find the id, "svxXXXXXXX"?

The ID which starts from jvx, svx, evx or uvx is assigned to virtual server, NW and GW. It's called System ID.

Please select a virtual server and go to "Info" tab. Then you can find "System ID".
Or, please search below keyword according to your service location on the search window in the upper right corner of the screen.

• Europe: evx
• United States: uvx
• Japan, Hong Kong: jvx
• Asia (except for Japan and Hong Kong): svx
