A fairly basic feature sorely missing from the Route10 is the ability to manage known hosts. I typically use custom host entries to redirect traffic to an internal host when hairpin NAT would otherwise occur. For example, I might run a speed test service on my network that is publicly accessible through a reverse proxy server at speedtest.domain.com. When attempting to access speedtest.domain.com from my LAN, I want it to resolve directly to the internal host IP, not my WAN IP, eliminating a hairpin NAT situation. Custom host entries can also be used as a DNS sinkhole.
I can manually add entries to /etc/hosts on my Route10, but I don’t want to layer CLI mods to my setup and the changes don’t persist after rebooting.
