Connection blocking occasionally blocks allowed traffic after wake from sleep
iMac running 10.6.2, with latest NIS software.
Occasionally, after waking up from sleep, Firewall reports/logs blocked connections (i.e., Windows File Sharing) that have already been allowed.
Even though the connection is already permitted, I have to "fix" the problem by adding a rule (e.g., trust zone, allow 192.168.1.1). I get the impression that the firewall software rereads all the rules after a change, as I can then delete that redundant rule, and everything works again with just the normal "allow any local network" rule.
Again, this is an occasional problem. Mostly, after waking from sleep, there aren't any connection blocking problems. Perhaps a timing issue with NIS and the interface (not) being up, leading to the firewall occasionally thinking that 192.168.1 isn't a local network?
My normal connection blocking settings:
When there is a problem with connection blocking after waking from sleep, I see this in the log, even though the rules are already there to permit the traffic:
