Solution
Yes. This can be done by opening 3 ports in the NAT/Firewall for the controller as shown below. No configuration changes are required on the home/AP router.

SrcIP     SrcPort          DstIP               DstPort       Action

  *              *        <controller-IP>      9292          allow

  *              *        <controller-IP>      9393          allow

  *              *        <controller-IP>      5000          allow

Step 2: Make sure the AP discovers/connects to Controller using L3 Discovery, i.e Discovered controller using IP address/DNS. 

To configure AP using Console to discover Controller using IP/DNS Name:

ip config net static
ip config address <IP ADDRESS>
ip config netmask <subnet-mask>
ip config controller name <Controller IP/ DNS RESOLVEABLE NAME>
ip config gateway <DG ADDRESS>
ip config dns add <address>
ip config save 
ip config write
