However, I regularly identify abusive actors on my web -server via the server logs. - -In addition, I have identified IP addresses and subnets directly within -Unifi's logs that the UDM did not block for whatever reason. - -This guide is meant to be another step in the process to manually block -abusive IP addresses or subnets that you have identified but are not -being automatically blocked yet. - -## Create an IP Group Profile - -To start, login to the Unifi machine's web GUI and navigate to the -Network app \> Settings \> Profiles. - -Within this page, choose the `IP Groups` tab and click -`Create New`. - - - -Each IP Group profile can be used as one of three options: - -1.
