Our network is configured by using multipel vlans. the wireless network is comprised of three different vlans (which is dhcp). and the mac mini is on a different vlan setup as a static IP. The setup is similar to the ones listed in the about cahcing service in the server help document.
Verify or configure :
If your MAC Mini (Caching Server is on a different subnet (VLAN) than your devices (iPad) trying to get updates for your applications, you may need additional configuration:
In the Server app Caching pane, click Edit next to Permissions.
Click the “Cache content for clients connecting from” pop-up menu, then choose "only some networks.”
Add local subnets by clicking the add button, then choose an IP address group name. (Add the Subnets of each VLAN you want to be able to connect)
If the IP address group you want isn’t listed as a choice, you can create it here. **(Must know your IP Networks)
**
To create a different IP address range, click the add button, then choose “Create a new network.” **(If the VLAN is not here...create it.)
**
Enter the IP address group name, a starting IP address, and an ending IP address. ** (Remember to enter the address range here.)
**
You can put an address range in CIDR notation (for example, 10.0.0.1/16) in the Start IP Address field, then the ending address will automatically be entered.
After you add the desired IP address group, click Create.
When you finish the configuration, click OK.
