.. cfgcmd:: set service dns forwarding serve-stale-extension <0-65535>
Maximum number of times an expired record’s TTL is extended by 30s when
serving stale. Extension only occurs if a record cannot be refreshed. A
value of 0 means the Serve Stale mechanism is not used. To allow records
becoming stale to be served for an hour, use a value of 120.
.. cfgcmd:: set service dns forwarding exclude-throttle-address <ip|prefix>
When an authoritative server does not answer a query or sends a reply the
recursor does not like, it is throttled. Any servers matching the supplied
netmasks will never be throttled.
