My understanding is that the clients requesting their updates are redirected (by Apple's own servers) to the caching server only if the caching server and the requesting client both appear (from Apple's perspective) to originate from behind the same (NAT'd) public IP address.

I haven't ever tried to do multiple public IPs (I only enable caching server once inside my home network as a test), but it looks like from the settings window that it is possible to have more than one public IP using your cache.

When the "serve clients with public addresses: on other networks" configuration is enabled, "client configuration" button gives generated DNS records which were also mentioned elsewhere in this thread (_aaplcache._tcp	259200.<dnssearchname> TXT record per network)
