I have some newbie questions about ifolder.

I have setup the ifolder server with private adres, and want to use
to get it on the outside. Where should I put the the static NAT table

On the BM server ? Where can I find docs about filters for this ?

When I sync my ifolder to a local workstation, how do I secure these files ? As far is I can see now they are not protected in anyway.

User A logs in, syncs his files, next day user B logs in, he can do
anything with the local files ?

Thanks for any help.
