Connection List/IP
The IP menu contains the parameters for exchanging IP data with the PPP
peer. Static routes can also be created from here for IP dial-on-demand appli-
cations.
IP/Mode
Write security: 3; Read security: 5
Setting to On (def) will permit this connection profile to negotiate PPP IPCP
with the PPP peer for exchanging of IP packets.
IP/NAT
Write security: 3; Read security: 5
The Express XL/XLT can perform Network Address Translation. This feature
is most widely used when connecting to the Internet. The Ethernet network
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 ne-
gotiated with the PPP peer (ISP). Multiple stations on the Ethernet side can ac-
cess the Internet simultaneously. See the section IP/NAT on page 43 for more
global options. Setting this option to On will cause the Express XL/XLT to
perform NAT. In the Off (def) position, the unit will route across the connec-
tion normally.
IP/Route
The IP parameters are configured in this menu. Adjusting these parameters is
only necessary for certain dial-on-demand applications. Usually the Express XL/XLT
will automatically discover the PPP peer’s networks using PPP IPCP and/or RIP.
