Specifying Static Source Ports

To specify static source ports for a Grid and Grid member:

1. Grid: From the Data Management tab, select the DNS tab, expand the Toolbar and click Grid DNS Properties.
   Member: From the Data Management tab, select the DNS tab and click the Members tab -> member check box -> Edit icon.
   DNS View: From the Data Management tab, select the DNS tab and click the Members tab -> member check box -> Edit icon.
2. In the editor, click Toggle Advanced Mode.
3. Member: When the additional tabs appear, click the Advanced subtab of the General tab. DNS View: When the additional tabs appear, click the Advanced subtab of the DNS Views tab. To override an inherited property, click Override next to it and complete the appropriate fields.
4. Complete the following:
   • Set static source UDP port for queries (not recommended): This is disabled by default. To override the value that has been inherited from the Grid, click Override. Select this check box to enable it and enter the UDP port number. You can enter a value between 1 and 63999. To retain the same value as the Grid, click Inherit.
   • Set static source UDP port for notify messages: This is disabled by default. To override the value that has been inherited from the Grid, click Override. Select this check box to specify a source port for notify messages to ensure that the firewall allows the zone transfer request from the secondary server to the primary server. You can enter a value between 1 and 63999. If you do not specify a source port, the appliance sends messages from a random port with a number above 1024. To retain the same value as the Grid, click Inherit.
5. Save the configuration and click Restart if it appears at the top of the screen.
