Thanks for pointing me to that file. That gets regenerated each time the router is rebooted, doesn’t it, from rom/usr/bin/gen_ovpn?
I use my Mango only as a travel router, not a main router, and it works just great for that. I can’t see using it as the main internet router, or really as an openvpn server unless I have a really slow internet connection, like 25/1. Still, I was surprised that the server options seem so limited.
