Trying to connect two identical subnets using two Zywall 1100's

Nimrod · February 2018

Hi all, I'm a noob to all of this so please be gentle. I have two physical locations with the same subnet, namely 192.168.2.0/24. I have a need to have two devices (one at each physical location) to be able to see each other through a remote link. The devices discover each other through broadcast traffic.

Using my Zywall 1100's on each side, I need to be able to have the Zywalls connect so that the two devices appear to be on the same subnet. For the sake of discussion device1 in location1 has a local IP address of 192.168.2.100 and device2 in location2 has a local IP address of 192.168.2.210. How do I connect the two locations so that they can see each other as if they were physically in the same subnet?

Thank you in advance for any help you can provide!

It seems you need the VPN to make two device can communicate with each other.
Here is the example:

Thank you for your response. That example shows two different subnets being connected. I have successfully done that using a VPN connection. That example shows a two subnets 10.10.10.1 and 192.168.20.1 being connected. I have two devices that absolutely have to be on the same subnet otherwise they won't work.
