What should an engineer consider when setting up the DNS proxy for web proxy?
A secondary DNS server in the DNS proxy is optional, and configuration commit to the firewall will succeed with only one DNS server.
A maximum of two FQDNs can be mapped to an IP address in the static entries for DNS proxy.
DNS timeout for web proxy can be configured manually, and it should be set to the highest value possible.
Adjust the UDP queries for the DNS proxy to allow both DNS servers to be tried within 20 seconds.
