Add setting to control the upper limit of the FQDN refresh timer
|
This information is also available in the FortiProxy 7.6 Administration Guide: |
The fqdn-max-refresh setting is used to control the global upper limit of the FQDN refresh timer. FQDN entries with a time to live longer than the maximum refresh value will have their refresh timer reduced to this upper limit. This allows the FortiProxy to dictate the upper limit in querying for DNS updates for its FQDN addresses.
By default, the fqdn-max-refresh time is 3600 seconds, and the configurable range is 3600 to 86400 seconds.
config system dns
set fqdn-max-refresh <integer>
end
