n
To edit an existing interface, click to expand the interface.
The Interface configuration window is displayed.
New Interfaces are enabled by default. To disable, toggle off Enable.
5. For Interface type, select IP Passthrough.
6. For Zone, select Internal.
7. For Device, select an Ethernet device or a Wi-Fi access point.

9. (Optional) Packet filtering is disabled by default. Toggle on to enable.
If packet filtering is disabled, traffic is allowed in both directions and it is the responsibility of
the external device to provide its own firewall.
10. (Optional) Allow all addresses is disabled by default. Toggle on to enable.
When enabled, this option allows forwarding between the source interface and devices
connected to this interface, which allows connected devices to forward and receive packets
without network address translation (NAT). This should normally be disabled unless it is
required for modem passthrough, because some cellular will disconnect modems that send
packets that are not from the carrier-assigned IP address.
11. Ancillary addressing is enabled by default, which provides an IPv4 address to the connected
device when the source address is not available.
a. For Ancillary address/netmask, type the IPv4 address and netmask to provide to the
connected device when the source address is not available.
b. For Ancillary gateway, type the IPv4 address of the network gateway to be used when the
connected device when the source address is not available.
