Configuring the JACE-4/5 for DDNS
The JACE-4/5 DDNS client set up in the ddns.properties file, which is accessible via
the Admin Tool.
About the
ddns.properties
file
The ddns.properties file includes four parameters, as listed in Table 5-3. Just like the
ras.properties file, parameters are listed in the form <parameter>=<value>. However,
unlike the ras.properties file, several parameters are preceded by a pound sign, which
you would need to remove to enable the parameter. For example, in Figure 5-7, the
domainName parameter has been enabled by the removal of the pound sign.
Configuring the
ddns.properties
file
Use the following steps to set up DDNS on the JACE:
Procedure 5-4 Configuring DDNS on a JACE-4/5.
Step 1 Using the Admin Tool, connect to and log into the JACE.
Step 2 Click the Network tab.
Step 3 Click DDNS Properties.
The ddns.properties file opens for editing (Figure 5-7).
Tip If you do not see the DDNS Properties button, maximize the Admin Tool.
