Can't login from remote site ie.

But if I configure workstation on LAN using then I can login
from remote site!
on that PC...

I installed iFolder 3.8 client and this comes up with server LAN IP when I
try installing on anew PC... suggesting its a DNS type issue.

NB: only one LAN card - using NAT on Router like I said works fine if
machine is configured whilst on lan!
