The following errors are showing up in our logs
Nov 9 00:10:03 SERVER_NAME com.apple.afctl: ip6fw: rule 7880: setsockopt(IPV6_FW_DEL): Invalid argument
We have a script that blocks unauthorized access using the following command
/usr/libexec/afctl -a IP_ADDRESS -t MINUTES_TO_BLOCK
The error would appear to occur when the MINUTES_TO_BLOCK has elapsed and something removes the rule.
The rule is removed from the firewall and there appears to be no ill effects, should I ignore the error or is it a cause for concern?
