Ionic tab not remembering which tab opened after back from opened page


i have 3 tabs inside my page

Home, Forum, Settings

inside Forum i have a link to open some page… so it open a new page with back arrow inside it…

after the opened page closed, it will back to the page with 3 tabs (*Home, Forum, Settings), but it open “Home” instead “Forum”.

is there any tricky method to make the tabs remembered which one opened… or i should set it up manually by code?
