Peplink Balance 20 Hairpin

I have a Peplink Balance 20 Firmware 8.1.3 build 5021

We have a staff network with WiFi

We have a cctv network on its own VLAN

We can access the CCTV system from outside of the LAN using the external IP and port forwarding to the CCTV equipment.

I would like to access the CCTV system from the Staff WiFi network using the external ip and port numbers.

is this possible?

Certainly. Make certain Inter-VLAN routing is on. (The example below is from a 310X but you should see something similar in a Balance 20.)

And, make certain you don’t have any firewall rules in the way.
