Thanks for answering, so it doesn't generate any impact by deleting that account? since in the second image it is displayed that the IP 184.108.40.206 associated with the admin account appears. And from what I understand, that IP is a local host.
Actually, from some point of 6.0.x, you can delete "admin" admin user directly without renaming it to something else. We do that all the time to virtually all FGTs we install for our customers. No particular side effect I'm aware of.
Just need to create a new admin user, then re-login in to it with the new user name. Then you can remove the "admin".
First, you are currently logged in as 'admin'. Your sessions are shown in the screenshot.
As long as you are logged in, you cannot remove the account.
Create a new administrative account with profile 'super_admin', log out, log in as the new user and delete the 'admin' account.
This will have no adverse effects whatsoever.
Second, what you observe is sessions to '127.0.0.1', not '220.127.116.11'. The first is the 'localhost' address, that is, the PC you are currently logged in to. The second is indeed a private address of a LAN which is unknown to you (no wonder). So in short, this is perfectly OK.
