Rangers boss Gary Waddock insisted the match had turned on referee Lee Mason's decision to give Ipswich their penalty shortly after Gallen had put Rangers in front.
Waddock said: "It turned on the penalty decision. From where I was, it looked as though the referee had said no, before changing his mind.
"It changed the course of the game - but I won't speak to him, because he won't change his mind now.
"We had taken the lead and got ourselves into a good position, but then that decision was made.
"It shouldn't affect us, but it did - and it seemed as though nobody in the ground thought the penalty should have been awarded."
"We keep getting ourselves into positions to win games and then not taking advantage, which is a concern.
"I wish we could have another game tomorrow, but instead we have this two-week break, and we will have to work very hard on the training ground before our next match against Plymouth."

"Last week, I was so low I could have walked under a door with a top hat on.
"But that is why I chose this career, and that is why I feel the luckiest man on Earth to be managing this fantastic club.
"It has been a tough week after losing at Peterborough in the Carling Cup, but it's about self-belief and we will try to enjoy this.
"Hopefully we can use this result as a springboard and move on from here."
"We deserved a bit of luck, because it has deserted us in recent matches.
"I'm chuffed to bits for the staff and the players, because we have been under a bit of pressure because of recent results."
