Hey everyone, I'm having some trouble with OpenVPN. I am very new to the software, this being my first time using it, so pardon any ignorance that may seem like it should be common sense. Here's my neofetch and ip route, please let me know if you need extra information about my system/config:

ego@ubuntu:~$ neofetch

ego@ubuntu

----------

OS: Ubuntu 22.04.3 LTS x86_64

Host: Z690 Extreme

Kernel: 5.15.0-89-generic

ego@ubuntu:~$ ip route

default via 192.168.0.1 dev enp3s0

192.168.0.0/24 dev enp3s0 proto kernel scope link src 192.168.0.2

192.168.1.0/24 dev tun0 proto kernel scope link src 192.168.1.1

My phone is currently successfully connnected to the VPN server and is assigned an address in the .1.0/24 subnet, but I can't reach my router or AdGuardHome admin panel web servers at their local IP addresses. SMB/SSH are working over the VPN connection just fine, and I can ping my Ubuntu server (which hosts AdGuardHome and OpenVPN) @ .0.2 but not my router @ .0.1

Success accessing certain things is clearly very inconsistent and I'm not sure what the problem is. I managed to get this all set up by referring to OpenVPNs website as well as utilizing ChatGPT to process and personalize the instructions for my needs, so I'm sure there are plenty of things that aren't configured entirely accurately, I'm just not sure where to look. Any help is greatly appreciated.

almost certainly your router and adguard installation only respond to web management on their own subnet.
