We've used Remote Disc to access a DVD reader attached to one computer on a LAN before. Now that we're all 'work from home', we've got a VPN setup that creates peer-to-peer connections between all of our location and all normal traffic flows fine across it.

However, from my computer, I can't "Remote Disc" to a DVD drive located on another users location which is connected via the VPN. Each 'location' is its own LAN. Example 192.168.2.0/24, 192.168.3.0/24, 192.168.4.0/24, etc

Is there some clever way to make this work. We have a use case where the DVD burner is needed in one location, but reading the disc is required in another.

As of right now when I click "Remote Disc" it only works from a computer on the LAN the DVD burner is attached to. When I click "Remote Disc" from a remote location, nothing shows up even though we're all connected via the VPN network.

    Who manages your VPN? They just need to allow Bonjour traffic across the tunnel for this to work. L2 just works and L3 needs a Bonjour proxy. serverfault.com/a/445696

  • @bmike had the correct answer. On PepLink routers there was a non-obvious field for setting up Bonjour Forwarding service. Once configured everything worked as expected.

@bmike had the correct solution.

On a PepLink Router, under LAN->Network Settings, you need to select Enable the 'Bonjour Forwarding Settings' and then set the Service and Client Pairs. In our case we set a bi-directional pair by selecting the VPN remote as Service/Local LAN as client and the reverse as well with local LAN as Service/VPN remote as client.

You need to also add matching pairs on the opposite end routers.

Many thanks to @bmike for pointing in the right direction.
