I am setting up a VPN on a USG60 (firmware 4.60) with the following scenario:

ISP Internet Router WAN IP: [WANRouter_Dymaic_IP] dynamic
ISP Internet Router LAN IP: [LANRouter_IP] static

USG60 WAN IP: [USGWAN] static

Ports 1701, 500, etc point to the USG
Internet ISP connection is under NAT

VPN works if I use this configuratión...

    VPN->IPSec VPN->Edit VPN Connection [VPN01_Conexion_VPN] -> Politica -> Política Local -> HOST, [WANRouter_Dymaic_IP]

... but: How can I configure the firewall so that the VPN works with the dynamic public IP of the router?

Thank you

    After talking to support it seems that the solution has been to create a HOST with the IP and assign this host to "VPN -> IPSec VPN -> Editing VPN Connection -> Policy -> Local Policy" it seems to be working and you can now connect to the VPN.
    Thanks to Zyxel and especially to Maria for helping me over the phone
