login session expired,I cant be logged on more tha one AP at the same time in the same web browser

I have 3 epmp 1000 APs in a tower. Each AP es mapped  to a public IP address with dirferent tcp port for remote access.
172.16.1.10--------->208.150.x.x:12010
172.16.1.20--------->208.150.x.x:12020
172.16.1.30--------->208.150.x.x:12030
Everything works well when accessing only one AP by typing into any web browser the pubic IP address htts://208.150.x.x:12010,but when I open a new tab, and type other AP IP addresss, and type enter, automatically the first AP diplay the mesagge "Your login session has expired. Please login again". I cant be logged on more tha one AP at the same time in the same web browser. But i can be loggeg on the firs AP in Firefox, the second AP in Crhome, and the third AP in iExplorer.

My software version is 2.6
