IP Pass Through: Although the Router mode is capable of terminating the PPP in the modem and
hence does not require PPPoE client software on the host PC, there are some disadvantages to Router mode
when only single-user support is required. For instance, Router mode uses NAT which requires ALG support.
IP Pass Through also terminates the PPP in the modem and does not require a PPPoE client on the PC.
However, IP Pass Through does not use NAT and is not limited by ALGs. IP Pass Through will work with
Ethernet interface to the PC.
When IP Pass Through is enabled, only one PC is able to access the Internet, and the DHCP server will
duplicate the WAN IP address from the ISP to the local client PC. Only the PC with the WAN IP address can
access the Internet.
