EDIT: stop with the 'must be misconfigured' posts/accusations. Things were working just fine for a very long time. Haven't been "under the hood" on the modem or firewall in over a year.
Running Untangle firewall with ATT primary WAN (passthrough) and another ISP as secondary WAN. Both interfaces obtain IP address via respective modems, but both have OpenDNS as primary, and Google as secondary. Things were working beautifully until about 2 weeks ago.
After a ton of troubleshooting, I've discovered any DNS over-ride on the ATT WAN connections just renders the connection just about useless. The Internet has tons of observations where ATT is 'handling' DNS to their own whims.
Instead of kicking ATT to the curb, should I think about enabling my DNS relay on Untangle NGFW and having it use the other ISP connection for LAN DNS lookups?
