Description of the options
•
Do Reverse lookup automatically. I want to see DNS name everywhere instead of
IPAddress.
In this option, Firewall Analyzer will perform reverse NS lookup of all IP
addresses automatically. This will be carried out for all the reports and the
only DNS names (whichever could be resolved) will be displayed in the
reports.
Use this option, if you want to see only DNS names of the hosts in all your
reports.
•
Don't Reverse lookup automatically. Let me get an option to do that in my
reports.
In this option, Firewall Analyzer will not perform reverse NS lookup of IP
addresses automatically and will display the IP addresses of the Source
and Destination that participate in the conversation going through Firewall
and if you want DNS names to be displayed for the hosts for a particular
report, you can use the ResolveDNS link in the report.
In each of the individual reports a ResolveDNS link has been provided at
the top. Clicking this link enables DNS Resolution for all the IP Addresses
of the unresolved hosts present in the current report. The status of DNS
Resolution depends on the default DNS lookup time, within which Firewall
Analyzer will try to resolve the IP Address.
This is an existing option. Use this option, if you want to see DNS names
of the hosts only in particular reports.
If DNS Resolution is in progress for any other Firewall Analyzer user, then the
subsequent user will see the message "Please wait, DNS Resolution in progress for
another user" when clicking ResolveDNS link. Once the DNS Resolution is complete
for the first user, then the DNS Resolution for the subsequent user begins
automatically.
• No lookup at all. I want to see IPAddresses everywhere.
In this option, Firewall Analyzer will display only the IP addresses of the
Source and Destination that participate in the conversation going through
Firewall.
If you select this option, Resolve DNS option will not be available for any
of the reports.
Use this option, if you want to see only IP addresses of the hosts in all your
reports.
Firewall Analyzer will resolve all the IP Addresses into DNS names which are
resolved by the 'nslookup' command from the machine where the product is
installed.
