Just acquired and installed AREDN on a Bullet Titanium M2, and it appears to be working, and have a tunnel client running as well. But I may have it configured poorly? I have the WAN disabled, and the LAN set to NAT, and the IP to 192.168.1.86 mask 255.255.255.0 gateway 192.168.1.1 and DHCP disabled. The tunnel works like this. The only ethernet jack on this thing appears to be a LAN jack (when I first tried to set it up, I couldn't connect to it until I did a ipconfig on my PC, and found I had an IP address belonging to the LAN part. I have it on channel -2 with a 5MHz setting.
