 Re: dns issue with ISP Redundancy?
From inside the network going out to the Internet.
DNS resolves to 0.0.0.0 on some sites. Also, the Tracker log shows that some domain-udp requests originate from the management console and others originate from the enforcement point. We only see domain-udp requests originate from the management console when we fail over to the second line. I can not prove it, but I assume the sites we can not reach are the ones were the domain-udp requests originate from the management console. |
