I've got a weird issue with my home OpenVPN server that in hoping can be figured out. Server runs on my Asus router with Merlin and I can connect without issues locally and remotely however accessing the home network works strangely. I can access my NAS using it's local 192 IP without it being connected to the VPN, but I can't access any programs on my media server Windows 10 PC using it's 192 IP, it needs to be connected to VPN then I can use the VPN IP to access only SABnzbd, but sonarr and couch potato don't work at all.
So I'm looking for two answers. Why can I use local IP for NAS, but not PC? And why can't I access couch potato or sonarr? Ports are forwarded.
