LB1120 intermittent DNS issue
My LB1120 worked flawlessly for around 6 months, but recently has begun to exhibit odd DNS behavior around twice a day. At those times, open sessions (VNC, video and audio streaming, etc.) will c...
I have a pair of LB1120 cellular gateways using AT&T sim cards. Both of them dump DNS periodically. Sometimes I can go a whole day or two but other times I have to restart them several times in a day. I have a load balancing configuration with a Ubiquiti USG router that has 2 WAN ports.
When DNS goes down they won't resolve new addresses. If I am streaming from a radio station or other continuous source it will keep playing but no other web sites will work until I restart the LBs. I am thinking this is AT&T's way to get me off their network. I do use quite a lot of data and don't have any other provider choices. No cable and no DSL where I live.
I've bought a couple of different connection monitoring outlets to try to auto reboot but this doesn't work because they are basically ping engines and when DNS quits resolving pinging remains just fine. Any thoughts on how to solve this probelm are most appreciated. My next step is to write a monitoring script to run non-stop on a Linux test box I have on the network and use it to trigger the outlet reboots when it can't resolve DNS via HTTP.
