Managing gateways via Public IP.

[BKYDCPSC]

Hi,

I have got myself confused.

I am currently managing gateways via private addresses ranges which are delivered over VPNs.

I have 1 central management, and it connects to all gateways on a private 192.168 address which is on the VPN domain. I know this is bad practice.

How do I go about managing the gateways via the public IP address and the external interface? Feel like I’m missing something very easy.
