I want to allow players to world2 from world1 then they can teleport back to world1 but they will arrive in the place they left!!

You should check out OpenWarp along with the help pages for it.

Hi there. We're cleaning out the issue tracker since we (mostly me) have mistreated it.

I'm closing this issue because it is outside the scope of what we want to do in Multiverse-Portals.
