I got a couple of computers that's never in the office so I have to make a remote office configuration.

I just wan't the agent to communicate with the server over https, could I only open up port 8383 in the firewall then?

Or do I have to open the other ports to? Like 8027 and so on?

In the settings for the remote office Desktop Central has the local server IP adress by default? Because it's there and I didn't add it.

Could I just change that to the WAN IP or the domain name i configured?

Some of the computers I installed the agent when they was on the LAN, do I have to reinstall those with the "Remote Agent"? or can I just take them to the LAN and move them from Local to Remote when they are connected on the LAN?

I have made a sub domain on the net that is medc.domain.com and also configured that on the DNS on the LAN, so on the internet It' goes to our WAN IP and on the local net the medc.domain.com goes to the IP of the local server with Desktop Central server.

Could I make the agents to use that domain instead and not use "Remote Office" at all, because they will communicate right both on LAN and WAN?

Thanks,
