IP Passthrough
IP Passthrough (IPPT) enables the first device detected on the specified LAN port to obtain the IP
address assigned by the mobile network. IPPT allows you to enable a one-to-one connection to a host
routing system. NOTE: When IP Passthrough is on, devices on other interfaces function normally.
However, when IPPT is enabled, the following capabilities are set through the host routing system and
web UI settings are not available:
• DMZ (Firewall)
• Port Filtering
• Port Forwarding
Turn on IP Passthrough: Check the box to enable IP Passthrough.
IPPT Interface: Select an interface from the drop-down (Ethernet1, Ethernet2, or USB).
