I have a PC based border router running 2.9.38. Since upgrading it to this version from 2.9.29, the DNS service randomly quits and requires a reboot to get things working again. My network is private and this router NATs as well. I use this router and a public DNS server for my network. When the DNS on the border router fails, customers cannot get to the public DNS server either so no one cans acces the Internet. Anyone else seen this?
I am using v2.9.38 for several weeks now and have not experienced that kind of a thing. Anyway, if DNS service fails and you have public entry of DNS on client side, everything has to work.
I would agree with you but that is not the case. Cannot get any DNS resolution when this occurs.
Have you tried disabling DNS service and remote DNS requests? I mean, can clients resolve anything from public DNS server when your DNS server is disabled?
Maybe that public DNS server is down. Are you sure it is running fine?
