I can't make it work thru a firewall (bordermanager NAT).

When I use it inside the private network, it works ok, using the DNS name
as the server name.
On the public network, the DNS name resolve correctly to the address used
on the server (NAT), but I can't connect. If I use the public address
instead of the DNS name it works. If I setup a new account, (not changing
the address of one that did work), I can never connect using the public IP.

I can't use IP address all the time because the laptop users would have to
keep changing the addresses, making the products useless.

I have to point out that when it do works, I have a message about the
certificate, and that I have to accept the certificates.

The iFolder web interface works fine.
