Monitoring

The runtime Virtual IP Address, Subnet Mask, and Gateway settings are logged as in 4.4. Events are generated when Dynamic Virtual IPs are learned, released, or expired; when there is a communication issue with the learned Gateway or DHCP server; or when duplicate IPs are detected. If duplicate IPs are detected at a Site, Dynamic Virtual IPs are released and renewed until all Virtual Interfaces at the site have unique Virtual IP Addresses.

Under Manage Network > Enable/Disable/Purge Flows the DHCP Client WAN Links table provides the status of learned IPs. From here you can request to Renew the IP, which will refresh the lease time. You can also choose to Release & Renew, which will get a new IP address with a new lease.
