The IP menu contains the parameters for exchanging IP data with the PPP 
peer.

Setting to On (def) will permit this connection profile to negotiate PPP IPCP 
with the PPP peer for exchanging of IP packets.

The Express L768/L1.5 can perform Network Address Translation.  This fea-
ture is most widely used when connecting to the Internet.  The Ethernet net-
work can consist of private network numbers.  When this profile is connected, 
all IP addresses on the Ethernet side are translated into the one real IP address 
negotiated with the PPP peer (ISP).  Multiple stations on the Ethernet side can 
access the Internet simultaneously.  See the section IP/NAT on page 29 for 
more global options.  Setting this option to On will cause the Express L768/
L1.5 to perform NAT.  In the Off (def) position, the unit will route across the 
connection normally.

The IP parameters are configured in this menu. Usually the Express L768/L1.5 
will automatically discover the PPP peer’s networks using PPP IPCP and/or RIP.

The PPP peer’s IP address or network can be set here, if known.  Leaving this 
at 0.0.0.0 means that the Express L768/L1.5 will determine the PPP peer’s IP 
and network using the PPP IPCP.

This network mask is applied to the IP/NET address for determining the PPP 
peer’s network.  If left as 0.0.0.0, a standard network mask is used.
