BlackBerry Mobile Fusion之UDS服务器需要能访问Apple APN的2195端口。

Apple APN的域名：gateway.sandbox.push.apple.com

the entire 17.0.0.0/8 address block is assigned to Apple, so you can specify that range in your firewall rules.
gateway.sandbox.push.apple.com
note: 17.0.0.0/8 is CIDR notation for 17.0.0.1 to 17.255.255.254
