DNS Database CNAME entries
We are testing DNS on a FGT 201E running FOSv6.0.8 and having issues with incorrect behaviour with CNAME entries. I am not finding a lot of discussion anywhere on FGT dns which leaves me to believe this is likely not a well used feature.
incorrect response from FGT:
> mail.sample.com
Server: destiny.sample.com Address: xxx.xxx.xxx.1
Name: mail.sample.com
Correct response from bind server
> mail.sample.com
Server: matthew.sample.com Address: xxx.xxx.xxx.11
Name: ghs.google.com Addresses: 2xxx:xxxx:xxx4:xxx::2013 xxx.xxx.xxx.xx3 Aliases: mail.sample.com
Packet captures show that the FGT is returning the CNAME of ghs.google.com but it is not resolved where bind returns the cname and the IPs.
FGT:
Protocol Length Info DNS 79 Standard query 0x0059 A mail.sample.com DNS 104 Standard query response 0x0059 A mail.sample.com CNAME ghs.google.com DNS 79 Standard query 0x005a AAAA mail.sample.com DNS 104 Standard query response 0x005a AAAA mail.sample.com CNAME ghs.google.com
Bind:
Protocol Length Info DNS 76 Standard query 0x0066 A mail.sample.com DNS 117 Standard query response 0x0066 A mail.sample.com CNAME ghs.google.com A xxx.xxx.xxx.xx3 DNS 76 Standard query 0x0067 AAAA mail.sample.com DNS 129 Standard query response 0x0067 AAAA mail.sample.com CNAME ghs.google.com AAAA 2xxx:xxxx:xxx4:xxx::2013
Any thoughts other than don't use CNAMEs?
Thanks
