Looking at another thread, it's nice of you to take the time to help that fellow with his router problem. You were very patient. Now then ...
I must be becoming a pest....
Since you brought it up:
1. A subject line of "HELLLLP" is not very informative.
2. Saying there's a problem and then finding out it was a typo on your part is slightly annoying.
3. Not learning to search these forums for answers (for example, password strength has been asked and answered many times) is more than slightly annoying.
That all being said, I think the only way to solve your user password issue from outside the LAN is to have the user authenticate to the server via PPTP, thus putting the user on the LAN; then he/she can access the user panel.
I too ran into the avatar permissions problem and have not solved it, but then again have not tried especially hard. Everything else about phpBB works great.
