Session end reason: tcp-fin and aged-out?

L2 Linker

Hi all,


I am using PA-850. I am having the problem. sometimes the internet is blocked. and I see in the monitor, the sesson end is: tcp-fin and aged-out. but after refresh some times, then I can access to internet.


Please help to advise how to fix it. please let me know if you need more information for this issue

TCP-FIN is a normal way to end a TCP session and doesn't indicate an error.

Aged-out is as normal way for UDP session to end. But make sure packets are flowing in both way in this case, check sent/received packets count.

Hi Santonic,


I checked and see that, session end reason aged-out: packets sent and packets recived is same numbers

but session end reason tcp-fin: sent and recviced is different.


please help to advise.

That's all normal. That doesn't indicate any errors.



Aged-out doesn't mean failed to get a further response as well..? For some reason, the other end is not responding to my query, after a certain amount of time, the session will age out and terminated. The reason could be my IP is been block listed, or some network path issue in-between.
