OpenVPN connect/visible to LAN subnet

[RamSense]

Hi community,

I have OpenVPN (ovpns2) running on Opnsense with IPv4 Tunnel Network 10.8.0.0/24, using Redirect Gateway and DNS Servers 192.168.1.1 (OpnSense)

My LAN (igb1) subnet 192.168.1.0 and subnetmask 255.255.255.0

VPN is running, I can see the LAN devices and other network items only available on local Lan.
I am using and running Roon Core/server on my Synology NAS. When I am outside and connected to VPN on my Opnsense I can start Roon on my iPhone and I can also see my local LAN endpoints to play music to. Only problem is that I can not see my iPhone as endpoint while on vpn. When I am at home on wifi, I can see my iPhone as endpoint in Roon.

I think it has to do with ROON detecting endpoints on the same subnet as LAN. How can I connect my VPN to the same subnet, or make my vpn connections visible to ROON LAN/subnet 192.168.1.0 / 255.255.255.0 ?

thank you very much for your help in advance!

There is an old thread about Roon's firewall restrictions: https://community.roonlabs.com/t/which-firewall-ports-destinations-does-roon-need-open-to-function/88309

If the assertion made there is true (Roon will only work on a flat network) then you may have to change your VPN from TUN to TAP with all the complications that will bring

thanks for your help and pointing me to the Roon thread... I will take a look over there to find some more info....
hope I get it to work in some way.

I have read over there someone setting up ZeroTier VPN and got it working.
So I will be looking for a good Opnsense - ZeroTier Brigdge guide and try that out. Sounds better than a openvpn TAP mode (?)
