Passthrough

In addition to the ZyXEL Device’s built-in PPPoE client, you can enable

 

 

PPPoE pass through to allow up to ten hosts on the LAN to use PPPoE

 

client software on their computers to connect to the ISP via the ZyXEL

 

Device. Each host can have a separate account and a public WAN IP

 

address.

 

PPPoE pass through is an alternative to NAT for application where NAT

 

is not appropriate.

 

Disable PPPoE pass through if you do not need to allow hosts on the

 

LAN to use PPPoE client software on their computers to connect to the

 

ISP.
