net 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 negotiated with the PPP peer (ISP). Multiple stations
on the Ethernet side can access the Internet simultaneously. See the sec-
tion “IP/NAT” on page 3-18 for more global options. Setting this option
to On will cause the Express 4100/4110 to perform NAT. In the Off (def)
position, the unit will route across the connection normally.
IP/Route
The IP parameters are configured in this menu. Adjusting these parame-
ters is only necessary for certain dial-on-demand applications. Usually the
Express 4100/4110 will automatically discover the PPP peer’s networks using PPP
IPCP and/or RIP.
Route/IP/Net
Write security: 3; Read security: 5
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 4100/4110 will deter-
mine the PPP peer’s IP and network using the PPP IPCP.
Route/Netmask
Write security: 3; Read security: 5
This network mask is applied to the IP/NET address for determin-
ing the PPP peer’s network. If left as 0.0.0.0, a standard network
mask is used.
Route/Static Route
Write security: 3; Read security: 5
When set to Yes (def), the Express 4100/4110 will add the network
defined above as an idle route in the IP routing table. When an IP
packet is routed to this idle route, the Express 4100/4110 will dial
using this profile. When set to No, an idle route is not placed in the
table. This is necessary for dial-on-demand applications and if the
probe feature is not used.
