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.
