The Bees will travel to Waltham Abbey on July 22 and Ebbsfleet United on August 1, a week before the League Two season kicks off.
Meanwhile, Barnet's trip to Northampton has been brought back to Friday September 4 to avoid clashing with England's game against Slovenia at Wembley the following day.
The rearranged match will kick-off at 7.45pm.
