Location area identity (LAI)
String {00000 999999}, default = 00000
The Public Land Mobile Network (PLMN) identification number of the cellular network.
Access point name (APN)
String {up to 99 char}, default = <empty>
The APN for the access into the cellular network.
Authentication
List box {None; PAP (legacy); CHAP}, default = "None"
None no authentication is used for the APN access.
PAP (legacy) –PAP (Password Authentication Protocol) authentication. We do not recommend
to use this option because of security issues (the option is provided to offer legacy systems com-
patibility). Username and Password are required.
CHAP CHAP (Challenge-Handshake Authentication Protocol) authentication. Username and
Password are required.
Note
Routing Mode “WWAN (AUX)” is added to the Static routing rules definition. When this mode
is selected, the routing Gateway parameter is ignored. The packet is forwarded to the Cellular
(WWAN) interface instead.
Routing rules are added / removed automatically when the Cellular (WWAN) interface is
opened / closed.
7.2. Routing
RipEX router supports both static and dynamic IP routing.
Static routing is based on fixed static definition of routing tables. Dynamic routing is based on
automatic creating and updating of routing tables. Various methods and protocols are used for this
purpose. OSPF and BGP standard routing protocols are available in RipEX networks.
7.2.1. Static
RipEX2 works as a standard IP router with multiple independent interfaces: Radio interface, Network
interfaces (bridging physical Ethernet interfaces), COM ports, Terminal servers, optional Cellular interface
etc. Each of the interfaces has its own IP addresses and Masks. All IP packets are processed according
to the Routing table.
Unlimited number of subnets can be defined on the Network interface. They are routed independently.
The COM ports are treated in the standard way as router devices, messages can be delivered to them
as UDP datagrams to selected UDP port numbers. Destination IP address of COM port is either IP of
a Network interface (bridging Ethernet interfaces) or IP of Radio interface. The IP address source of
outgoing packets from COM ports is equal to IP address of interface (either Radio or Network interface)
through which packet has been sent. The source address can also be assigned to Local preferred
