pfsense DNS Resolver fails to resolve some aws elb domains
-
I am facing a really weird failure to resolve DNS entries from AWS using pfsense resolver.
Can someone try:
internal-OpenPlatformElbInternal-1348256092.us-west-2.elb.amazonaws.com.I a use both cloudfare and google DNS servers on both ipv4 and ipv6.
When I query the dns servers directly they resolve but pfsense persistently refuses to resolve this while resolving others without problems.
When I use the lookup diagnostic, it always fails:
Host "internal-OpenPlatformElbInternal-1348256092.us-west-2.elb.amazonaws.com." could not be resolved.I am still trying to debug it but even after level3 log level I am still clueless.

Found the problem: the aws reply was with private IP addresses and they were dropped by default pfsense setup.
See https://www.netgate.com/docs/pfsense/dns/dns-rebinding-protections.html for how to enable "Private Address support".
