remove IP address

I’d like to know how to remove IP address from USB anywhere app(USB HUB). How to secure groups by setting up the password for each group.

It sounds like you are asking about the Connection List, which is accessible via “Edit / Connection List” in the AnywhereUSB Configuration Utility.

Here is a related KB article:

As to your second question, unfortunately, this is not possible with the AnywhereUSB G2 family.
