Link: IP Passthrough
When you click the IP Passthrough link, the IP Passthrough page appears.
IP Passthrough
The IP Passthrough feature allows a single PC on the LAN to have the ARRIS Gateway’s public address assigned
to it. It also provides PAT (port address translation) (or NAPT – network address and port translation) via the
same public IP address for all other hosts on the private LAN subnet.
Using IP Passthrough, the public WAN IP is used to provide IP address translation for private LAN computers.
The public WAN IP is assigned and reused on a LAN computer.
