4 Administration, Configuration and Status
About Addressing – Devices connecting to cellular networks are assigned an IP address by the serving network.
Address assignment may either be static or the unit will be dynamically assigned an IP address, depending on
arrangements that you have made with your wireless network operator. Dynamically assigned IP address remain in effect
for a period of time assigned by the network operator, usually at most a small number of hours.
Ctek’s Z Series includes features that manage the temporal nature of dynamically assigned wireless IP addresses. Using
the Wireless Configuration screen you can configure your router to use a Dynamic DNS (DDNS) service. Ctek operates a
DDNS test bed that allows our customers to observe the performance and reliability of DDNS with their applications. For
large-scale commercial applications Ctek recommends that users configure their own DDNS, managed and maintained
with the customers ongoing IT operations. The Z Series may also be configured to operate with a standard DNS having
Dynamic DNS capabilities. Examples of this type of service would be
Berkeley Internet Name Daemon (BIND) and Microsoft
Server 2000 and up.
Beginning with SkyRouter release 4.2 Ctek offers two additional DDNS capabilities. First, VDDNS provides information
exchange between each SkyRouter endpoint and Ctek’s VDDNS servers. VDDNS in turn presents the user with a map-
based presentation of their endpoints and the status of each endpoint. Also, if enabled Ctek’s network management
capability further enhances VDDNS by gathering a full set of important network parameters and storing this information on
cloud servers.
4.1 Getting Started
Once the PC has been set up properly and physically connected to the router you are ready to begin configuring the
router for your application. To access the Administration menu use any web browser pointed at http:// 192.168.1.10. A
login screen appears as shown below. The default User ID is “
ctek” (without the quotes) and the default Password is also
“
ctek”. Be sure to change the user ID and password and record your new selections. Later in this document, the set-up of
additional users is covered.
Note: Beginning with release 4.2 a login attempt counter in in place. Three consecutive failed login attempts on either
the LAN or WAN connection will cause that method of access to lock for 15 minutes. Within that 15-minute window, any
subsequent attempts to login will extend the locked period by an additional 15 minutes. This feature is standard in all
SkyRouters. Additional intrusion prevention capabilities can be found in the TCOPlus option.
