You just need to shoot at the entity linked to the trigger brush, not at the trigger itself, and it should work.
I see now. I still sense something's wrong however, although I'm not sure what the health key is initially intended to do. From my test after what you said the only way to make the door have to be shot open is to set the "health X" flag into the door itself, not any trigger (at that point the door likely works without any trigger attached to it even). So if the health flag is to be set in the func_door and the door itself be shot open then, what purpose does the health flag in a trigger_multiple and other triggers have?
The way I see it a trigger with the health flag in it needs to always activate when that trigger is shot. It's what the description also says when you select a trigger and read its entities definitions ("health: amount of damage that has to be dealt
to the trigger to activate (it then won't respond to merely touching it)"). If someone wants the door to have to be shot open they just set the health key in the func_door rather then the trigger, and if they want to have a separate trigger needing to be shot to open a door have the health flag in the trigger.
I think its important to be able to make shoot triggers around maps at this point as well. I initially tried this on my map hoping I could make a shoot switch for a trap door, so if this won't be changed I'll have to go with other types of switches if there isn't any way to make a separate shootable switch for a door. Maybe at least a toggle key or spawn flag could be set up to allow shoot switches to work?
