They’re both functioning as routers at the moment, the topology is:
internet fiber cable <---> ISP Router <---> OpenWRT Router <---> (ideally VPN'd) client devices
Both routers are handling DHCP on their own LANs, and if the OpenVPN service is stopped, clients connected to the OpenWRT router can connect to the internet without any apparent issue.
Good call, I haven’t yet but I think I should in any case. I got big plans for this little fella and network administration is one of the gaps in my education I’ve been meaning to fill in for a while now.
