Changing IP Addresses

If desired, you can change your UTM-1 appliance's internal IP address, or the entire range of IP addresses in your internal network.

To change IP addresses

1. Click Network in the main menu, and click the My Network tab.

   The My Network page appears.

2. In the desired network's row, click Edit.

   The Edit Network Settings page appears.

3. To change the UTM-1 appliance's internal IP address, enter the new IP address in the IP Address field.
4. To change the internal network range, enter a new value in the Subnet Mask field.

   Note: The internal network range is defined both by the UTM-1 appliance's internal IP address and by the subnet mask. For example, if the UTM-1 appliance's internal IP address is 192.168.100.7, and you set the subnet mask to 255.255.255.0, the network's IP address range will be 192.168.100.1 – 192.168.100.254.

5. Click Apply.

   A warning message appears.

6. Click OK.
   • The UTM-1 appliance's internal IP address and/or the internal network range are changed.
   • A success message appears.
7. Do one of the following:
   • If your computer is configured to obtain its IP address automatically
     (using DHCP), and the UTM-1 DHCP server is enabled, restart your computer.

     Your computer obtains an IP address in the new range.

   • Otherwise, manually reconfigure your computer to use the new
     address range using the TCP/IP settings. For information on configuring TCP/IP, see TCP/IP Settings.
