Since this is Home sharing then all you need to do is use IP's instead of DNS address
Example card box Box
Spiderbox 7000hd
IP OF Spiderbox 6000hd + admin pass
Spiderbox 6000hd
192.168.1.xxx 12000 admin pass
[ IP address obviously being your Spiderbox 7000hd IP Address ]
with Home sharing you only use IP Address to make the connection please remember this because a DNS address simply cant work in Home sharing I USE PORT 12000 Only as example so it needs to be open/forwarded in TCP on your router if this is port you are using .
I'm sure someone may post a better example this is just a ruff idea to get you going .
Good luck : )
