Chapter 4: Configuration Overview
IP/Mode
Write security: 3; Read security: 5
When set to On (def), this connection profile negotiates PPP IPCP
with the PPP peer for exchanging of IP packets.
IP/NAT
Write security: 3; Read security: 5
The Router Option Module can perform Network Address Transla-
tion. This feature is most widely used when connecting to the Inter-
net. 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 negotiated with the PPP
peer (ISP). Multiple stations on the Ethernet side can access the In-
ternet simultaneously. See the section IP/NAT on page page 4-7 for
more global options.
When set to On, the Router Option Module to perform NAT.
When set to Off (def), the unit will route across the connection nor-
mally.
IP/Route
The IP parameters are configured in this menu. Usually the Router Op-
tion Module 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 Router Option Module will de-
termine 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/Force IP
Write security: 3; Read security: 5
When set to Yes, the Router Option Module will force the PPP peer
to use the IP address in the IP/Net for this profile as its WAN IP ad-
dress. Normally this is set in the No (def) position.
