Rules containing domain objects bypassed in rulebase
Symptoms
  • Rule containing domain object, as source or destination, is bypassed in the rulebase. Domain object contains domain such as ".youtube.com"
Cause

Gateway does not use alias name for DNS resolution. It uses reverse DNS resolution. E.g nslookup on www.youtube.com returns:

Server: UnKnown
Address: 67.210.167.66

Non-authoritative answer:
Name: youtube-ui.l.google.com
Addresses: 209.85.225.93
209.85.225.136
209.85.225.190
209.85.225.91
Aliases: www.youtube.com

When you do an nslookup on 209.85.225.190 it returns:

Server:  UnKnown
Address:  67.210.167.66

Name:    iy-in-f190.1e100.net
Address:  209.85.225.190
