Finishing a stripped front door
 

I've had my internal doors dipped and stripped and I'm in the process
of sanding and waxing them, and I'm very pleased with the results.

The front door needs attention, and to make its internal side match the
other doors (and just because it's caked in 120 years of crappy paint)
I'm thinking of sending it off for stripping too. On it's inside I'm
planning to wax it to match the others. But I'm thinking of my options
for the outside if I don't just paint it again. Staining is the obvious
answer, or perhaps varnish. I really like the glowing sheen you get
from wax, but I guess this isn't durable enough for outside (although
in fact the door is very well sheltered, being recessed into a kind of
porch, although not one with a door of its own if you see what I mean).
Any ideas for what would work best?
