Thanks Phil, I got the port forwarding working and now have control (yeah right

) of the observatory via remote connection.
I consider team viewer and had several conversation at the conference over the weekend about which remote software was best. Most people said Radmin, some did like team viewer. In the end it was a cheap investment for Radmin.
What I did for port forwarding I googled how to port forward for my particular router / modem and there was a site that had a step by step approach.
I take your point about changing the port and I will look into this to see if Radmin has the capacity to shift ports.
