TacticalRMM - Security

[notverypunny]

So I've been testing TacticalRMM in our environment and after reviewing with some colleagues, we need to tighten control to the admin interface. I've followed the instructions here https://wh1te909.github.io/tacticalrmm/securing_nginx/ and it works to block the public IP addresses, but as soon as there's ..... *** googling and a few more grey hairs*****

So the syntax in the documentation might work with escaped chars and other foolishness, but I found that using

SecRule REMOTE_ADDR "!@ipMatch xxx.xxx.xxx.xxx"

instead of

SecRule REMOTE_ADDR "!@eq IP1"

allows for use of simple formatting as well as CIDR Ranges

Now we all know!
