[44net] 44net on Ubiquiti Unifi Controller and USG

Hi, Anyone out there familiar with adding the 44net to a Ubiquiti USG via the UniFi controller....??? I had it working by forwarding IPIP to a Linux box on my inside network, but it quit working after a few days. At first, I thought Comcast was blocking Protocol 4, but running tcpdump on the WAN interface shows the packets are there, but not being forwarded to the inside network. Because the USG has the same OS as the EdgeRouter, I followed the AmprNet setup steps for the EdgeRouter. The rub there is the config does'nt get saved in the USG because it's over-written by the UniFi controller. In order to store the config, you have to add a config file (config-gateway-json). It works...but it's not pretty (one example is my internal network is not nat'ing outgoing packets to the 44 network). So long story short...has anyone else done this or had experience with it....??? Feel free to reply here...or reply via my email listed on QRZ... 73's -Albert
