Figure 3-4 Network Settings

You can change the following Network Settings:

Domain Name—Enter the domain name for your organization (e.g. cisco.com)

Hostname—Enter the name of the appliance as defined in DNS (without DNS suffix)

IP Address—Enter the IP address of the eth0 interface on the appliance

Subnet Mask—Enter the corresponding subnet mask

Default Gateway—The default gateway for the network to which the appliance is connected

Nameserver 1—IP address of the primary DNS server

Nameserver 2—IP address of the secondary DNS server

Step 3 Click the Save Settings button to save the changes that you made.

Step 4 Once changes are saved, you need to restart the Guest Server to ensure all processes use the correct IP address. Click the Restart button, and the restart process will begin on the Guest Server within 60 seconds.

Date and Time Settings

Correct date and time are critical to the Cisco NAC Guest Server. The Guest Server authenticates guest users based upon the time their accounts are valid. It is important for the time to be correct so guest accounts are created and removed at the correct time. If possible, Cisco recommends using a Network Time Protocol (NTP) server to synchronize the time and date.

Step 1 From the administration interface select Server > Date/Time Settings from the left hand menu (Figure 3-5).
