F5 LTM - How do you restrict management access to the GUI ?

After finding this funky little command the other day I thought the readers of Fir3net may find it useful. Its especially handy when your LTM/GTM is placed directly onto the public network i.e not behind a firewall.

Command

To restrict access to the Web UI the following command is used,

root@f5ltm1(Active)(tmos)# modify sys httpd allow replace-all-with {  10.0.0.0/12  1.1.1.1/23  }

Additional

Note : This command does not restrict traffic to the Virtual Servers, only to the web management interface.
