Hi, I've just signed up for a JUSTCLOUD account, the online backup isn't working and the company advise the follow:

If your Firewall is blocking the Just Cloud application you will need to allow the following hosts / ports:

backupgrid.net Port 80/443
upld.storage.googleapis.com Port 80/443
You may also need to enter a destination IP:

backupgrid.net - 184.154.150.140
upld.storage.googleapis.com - 173.194.67.132

How do I do this?

Thanks
