i have admin page and i wanna restrict the access but not with IP address because i have dynamic IP address and i don't want to add/remove each time. so is there any further option to restrict the access to admin page?
Have you got APM? you could put a policy in front of it? And/Or. Do you have say a App at https://myapp.com and the admin page at https://myapp.com/admin? Or some other arrangement? (IE how would the f5 know you or the user is going to that page?)
