Ok, quick background. My isp is very particular regarding sonarr, radarr and the likes, thus i have a VPN susbscription that runs through a seperate mini pc with gateway ip as 192.168.1.1 . My unraid server has an ip of 192.168.1.4 and connects to the internet through the vpn gateway at 192.168.1.1 . My router provides standard access (no vpn) for normal browsing but on a seperate subnet (192.168.5.1) and has dhcp server enabled (192.168.5.2-254). both the vpn gateway and router are on the same switch so I can connect to the unraid box from my 192.168.5.* computers. (this is needed for my kodi shares).
now the question. I want to enable an openvpn-as docker to allow me to connect to the unraid box and subsequent shares/dockers when away. Is that possible given the openvpn server would have to have a seperate ip (192.168.5.*) in order to pass the ports from the router to it. I only have a single NIC in the server.
Is this only possible if I install a second NIC and connect that to the switch also?
