The Belfast side travelled across the Irish Sea - their first trip to Glasgow's south side - after having stepped in to host a fundraising match last May when the former Scottish champions found themselves mired in a financial crisis that eventually led to their liquidation.
Now reformed but playing in the Irn-Bru Third Division, Rangers proved too strong for the Northern Irishmen as they secured victory with goals from Chris Hegarty and youngster Andrew Murdoch.
Light Blues boss Ally McCoist paid his part-time visitors full respect by putting out a strong starting line-up, but Rangers struggled to get out of first gear in the early stages, mustering only an Ian Black drive on the half-hour mark before surviving a scare as Matthew Tipton pulled a decent chance wide.
It took until three minutes before the half-time break for the hosts to net as Hegarty found the corner of the goal from Fraser Aird's deep cross.
The second half was interrupted by a raft of substitutions.
Linfield captain Peter Thompson did have the ball in the net after 65 minutes only to see his big moment ruined by an offside flag.
However, Rangers wrapped it up with the last kick of the game as midfielder Murdoch's deflected 25-yard drive deceived Alan Blayney and found its way home.
