Hey Terry...I got that. And Tyson was doing that, too...if he even merely
thought I was out front, boom, over the puppy fence. There are things that happen accidentally that might lead to him being out front by himself. In that case, I wouldn't want the front door to be seen as bad. If your dog somehow ends up being out front by himself, you want him to come to you through ANY door. If you establish the front door as bad, you may have recall issues (from the front door) in the future (i.e. what dog wants to willingly come to someplace that is has been established as bad?). I am only suggesting that you not equate coming to/in the front door as bad because of experience...
I had a foster Shar-Pei who was a runner, can you say UGH?!
You want to focus on the jumping issue. There are many exercises you can do to modify that behavior which will focus on catching him doing it right

Most will require help from a friend or family member (since you can't be in two places at once) and time.
One thing you can try is have someone in the house watching him as you go through the following steps:
1. put him out back.
2. come back in and go out front.
3. when you go out front, have your helper watch his behavior from inside the house.
4. as soon as said helper tells you he is starting to show signs of stress and look like he might want to jump,
5. go back inside and then out the back door (He'll be like "hmm...cool, dad's back.).
6. Don't say anything to him, just walk out back, stand there for a minute or two, and then go back inside,
7. wait a minute or two and then go out front.
8. Lather, rinse, repeat (hopefully being able to increase the length of time you are out front a little at a time).
I wouldn't do this for more that 15-20 minutes per session, or you might reach his threshold (the point at which they are too stressed to think). On the last successful out-in-and-out of each session, I would offer a reward (food, toy, bone...whatever he responds to best).
Hopefully someone else, either on this forum or a trainer in your area, can give you some more ideas.
Good Luck!!!!
