The installer..

[RadoX 0]

I would like the installer to ask if you want to be active or passive and with some explanation of what it does and what needs to be done to be in active.

I would see it like it is in connection settings with a button behind that states "More Info" or something like that, "?" mark maybe and it would open a window with a short description.

Good idea!

Actually the installer could make a small test (with user permission) and determine it.

This way IMHO would be the best:

1. Describe what is active and passive.

2. Ask for what kind of activity client will be used, if user behind router and if user have external (non NAT) IP (disabled if lan-only selected).

3. Show dialog for mode selection (like in hub properties) then...

4. If it's lan-only, set active mode by default or if user behind router set passive and suggest faq on setting up active mode behind router.

5. If it's wan-only, set passive mode by defaul and if user have have external (non NAT) IP place button/link near it's inputbox to test it. If test will not fail set active by default.

6. If it's lan/wan, set active by default, if user have router set passive and suggest as in 4.; if external IP test failed just suggest to set passive mode for all external hubs.
