FQDN Address Objects used in Access Rules do not resolve after a period of time
03/26/2020 23 15696
While using FQDN Address Objects in Access Rules, they will stop resolving after some time.
After 21 tries, the SonicWall will stop trying to resolve the FQDN completely - that works as expected.
Passing the cursor over the FQDN address object in the Access Rule will show a status Unresolved and a packet monitor will return packet drops due to Enforced by Firewall Rule.
This issue has been resolved in the latest version of SonicOS 6.5 firwmare and has also been resolved in SonicOS 6.2.9+ and SonicOS 220.127.116.11+.
It is recommended that customers who are running older firmware versions upgrade to the latest general release.
For customers who are unable to upgrade at this time please contact the SonicWall technical support team to request hotfix 17472.
