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.
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.
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.
