firewall settings for Solstice Backup 6.1

Hi All,

I'm trying to allow automated remote backups using the Solstice product 
through my firewall, but it seems to be opening random ports. Does 
anybody have info on the  port usage for Solstice Backup? Or where that 
documentation might be? I don't see it anywhere in the docs. I can open 
a range but would prefer it to be as small as possible.

Thanks,
Chris
