Hi everybody,
we got a lot of syn-packets which were dropped by the rule any-allow. But we haven't this rule, so is it a inbuilt rule and
why do i need a DoS-Rule to be protected against Syn-Floods if there is a builtin rule.

So it should be a bug.
Maybe restarting some services will solve this but I can't say you'll not see same behaviour then, or not.
Best; I advice an upgrade to 5.0.11

Hello Sir,
Do you have a DOS protection profile configured on your PAN firewall..? As per my knowledge, PAN is not having such inbuilt rule on it. Could you please expand the session details as mentioned below and update here.
Thanks

did you check zone protection ?
if no zone protection or dos protection is used then better to open a case.

Maybe you have flood protection turned on in a network profile? That might do it.

Hello kdd,
From the description we see that the inbuilt rule has taken charge. What we will have to look is at the time of issue did we see any DOS or zone protection profile counters triggered.(If they are configured )
This can be seen by " less dp0-log dp-monitor.log" Also we can check the commands to see the triggers for the syn flood
show dos-protection rule <rule name>
show zone-protection zone <zone name>
Example for Dos counters:
