button. This displays a
line entry in which you can enter an IP address.
Whitelist entries can either be single IP addresses (e.g., 50.40.20.15) or IP
addresses followed by a CIDR netmask (e.g., 50.40.20.0/8) allowing subnets to be
whitelisted via a single whitelist entry. Whitelists only apply to the cellular (WAN)
interface. No whitelist filtering is possible on the LAN interface.
Since all VPN traffic is presumably between trusted hosts, whitelist entries are
ignored (but not deleted) when an OpenVPN or IPsec tunnel is configured.
To remove whitelist entries, click the checkbox of the entry and click on the
