A ping on the net says the host is down.
While I am a newbie when it come to TCP/IP I'm convinced something about the Airport Extreme is blocking the GC100. I've read something about port forwarding but I don't know enough about that. Usint itest and the avove command it reports back that it can't find 192.168.1.15..the 'literal' button along with the other two remains greyed out.
(We are going way off-topic, but I will try to help you.)
To be able to help you further, I need some additional information about how your network is connected (you can see it as a kind of check-list):
- Am I correct in assuming that the Airport Extreme is used to connect to the internet?
- Do you use static IP addresses or are you using DHCP served by the Airport Extreme?
- Do the Mac Pro, the Mac Mini and the iPad have an IP address in the range 192.168.1.x (where x is a number between 1 and 254, on your Mac Pro you can find these settings in the 'System Preferences' under 'Network' where either the 'Ethernet 1' or the 'Ethernet 2' is connected and has an IP-address)?
- Are the Mac Pro, the Mac Mini and the GC100 connected with one of the LAN ports of the Airport Extreme (either direct or using an switch)?
- Is the iPad connected to the Airport Extreme using WiFi?
- Is the Airport Extreme connected to your internet modem using the WAN port?
- If you are using dynamic IP addresses, is the Airport Extreme the only DHCP server in your network?
- If you are using static IP addresses, then please make sure each address is unique!
- If you are using DHCP then please make sure the GC100 is set to use DHCP, and not using a static IP address
As I have mentioned in my previous message, the GC100 will not respond to ping, this is normal (my GC100 also does not respond to a ping).
As it is possible to connect to the GC100 and configure it using a Mac Mini and a switch, I think that you have a problem in the network settings of the GC100.
Because the IP address that you see in iHelp is not necessary in the same range as the rest of your network. This information is send by the GC100 using a beacon (a special kind of network message), and it can be that the IP-address you see is set to a static value in the GC100 which does not correspond to the rest of your network.
It is also possible that there is an other device in your network that also has the IP-address 192.168.1.15 that is causing troubles. All IP-addresses in the same network must be unique and end with a number ranging from 1 to 254, 0 and 255 are not valid.
So for your Mac Pro and iPad to be able to connect to the GC100, they should have an IP-address starting with '192.168.1.' but not have 192.168.1.15 !
Please note that 'Port Forwarding' is used to be able to access for example a web-server on you internal network from the outside which in this case is the internet, you do not need it on your own LAN/WiFi network to access your GC100.
Hopefully this makes some thing a little bit clearer for you...
