Hi

I have a new Profilux 3.1nEx which is connected to an apple express, which in turn is connected to my WLAN at home & works fine

I'd like to extend this so that I can access my profilux externally but I have no idea how to do this. At home I have;

Wireless router / modem by TP-LINK ( 300Mbps wireless N ADSL2 + modem router ) ( not sure about the password )
Subscription to DYNDNS host name
An iMac with the DYNDNS updater installed
A laptop running Windows
A new Airport Express ( mentioned already ) ( Dec 2013 model )
An Airport Extreme ( unused ) ( Dec 2013 model )

I live in Phuket and despite trying, I cannot find any remote access assistance to set this up.

Thanks

Robert
