Get all eight badges from the johto region and then beat the Pokemon league to go to kanto
You first have to beat the Elite Four for the first time and then you have to get all of the Kanto Badges and he'll let you pass
Beat the Kanto Gym Leaders CFS
If you mean the guard by the elavator, you can't get passed him.
I don't believe this is possible, as they tightened security after Goldrenrod's Radio Tower incident (Source the guard at the bottom of the stairs).
Go find Prof. Oak, then he will give you access to Mt. Silver. It's located beside the entrance of Indigo Pleateau (if you took notice, previously there'll be a guard blocking you). There locates your destination, Mt. Silver. Pokemon Trainer Red is at the top of Mt. Silver, so prepare to fight the strongest trainer in all Pokemon history!
