so 5220 - 9.0.5
I have a syslog client and syslog server.
the path goes through my PA.
I have a rule basically says any internal ip is allowed to the syslog server if the app it syslog
that doesn't work, the packets are too short for the PA to distinguish them .. sigh so add in unknown - udp .
now they go through.
next problem tcp syslog on port 514 - default for centos and rhel when using tcp
pa don't think syslog goes on port 514.
okay application override
I say any internal ip going to syslog server on tcp 514 . make it syslog application.
doesn't work . my session are still marked as unkown ... again i am guessing causes it too small.
WTF do you do .
I can see packets on both side. client and server .. and the client is trying to send the pa is not letting through.
FFS 🙂 sigh
any suggestions. I am thinking of just setting any app as long as its port 514 hopefully that will fix it

tried allowing any app id but to that ip and only port 514..
no luck 😞

What do you see in the traffic logs ? Is it actually using syslog default port?
Can you try to configure policy for app - syslog and port any?

Have you tried setting CentOS to send syslog over 514/UDP?

@OtakarKlier Not sure why I have to change my setup to make he firewall work :).
So the reason I am using TCP over 514 is that the reliabe transfer setup for syslog. I can guarantee messages being sent from one server to the central logging server.
The issue seems to be that the PA doesn't allow traffic to flow from client to server and back. because it can't id (my guess why the packets aren't flowing).
initially I have it as
any int ip to syslog server allow applicaiton syslog on port 514 udp and tcp.
UDP works fine. but when i tried my tcp connections. no go.
So did some investigating and found that PA application syslog doesn't recognise tcp/514 as syslog ..
So I thought this is simple ! I do an applicaiton override for any int ip to syslog on tcp 514 say its syslog application.
that didn't seem to work ! when i look at current session they still show up as undecide .. so it just gets stuck and ages out.
So what next ! I have raised this with support ..
but why do I have to change my setup to make the firewall work properly
