When I connect my client to the server remotely, I am unable to access any of the devices on the LAN. My internal network is 192.168.x.x and my client receives an address of 10.8.0.x.
I tried changing the IPv4 subnet to match 192.168.x.x and bricked the router. Reverted to 10.8.0.0/24.
Do I have to make changes in LuCi? Is it due to being TUN and not TAP? How can I get 10.8.0.x to speak to 192.168.x.x?
Hmm I only got experience with wireguard, and a very little with openvpn on non gl firmware.
It sound to me, you did everything correctly even allowed remote access to lan, please leave the subnet as is, there isn't really a ip conflict.
My guess points to the routing, I think you miss the route 192.168.8.0/24 in your tunnel, and I'm thinking you may need to add some openvpn configuration pushroute option in your vpn config.
Atleast it sound like that this is the issue.
Edit:
I striked through the word push, because that may be wrong and conflict with policies when they are in use and gateways, you just want a static route, which I believe the route property does, maybe push is still valid, I got told to never push routes, but I think this stackoverflow explain this pretty well.
i’m not sure if it’s related but is hardware acceleration enabled? in my case with flint 3, there were a problem with hw acceleration when connecting through lan→wan→lan
Please confirm the VPN client is connected to the Flint3e VPN server.
Check if you can access the Flint3e GL GUI via the VPN server interface IP: 10.8.0.1.
