Users couldn't access the link "www.santander.com.ar" from global protect VPN, this is a normal bank related link so everyone can access though outside network, In our office structure Trust-VPN & Trust-Internal both sources zone are allowed to access "www.santander.com.ar" with general policies. As per policy Trust-Internal user have access the link through "PAN-INT2EXT URL FILTER" rule but Trust-VPN couldn't access the error is below
hit policy "PAN-INT2EXT URL FILTER update" and application - incomplete and session end reason - aged out
Can anyone please help to fix the issue
I tested on my PC behind the PA i see same behaviour.
Did the PCAP no drops.
Did this ever worked?
Only way to know the exact reason is to enable debugging on the PA.
If i get time today i will do that and keep you posted.
Tested again today saw this Global counter incremented
tcp_drop_packet 2 1 warn tcp pktproc packets dropped because of failure in tcp reassembly
do you have uplink to more than one ISP?
In PCAP today i saw fw was dropping syn ack from the server i think might be because it was receiving syn ack more than 5 secs due to this config
TCP default timeout: 3600 secs
TCP session timeout before SYN-ACK received: 5 secs
In my case i have single link to ISP and i did below changes to make it work only for testing purposes:
In Prod I do not recommend to make those changes
set deviceconfig setting tcp asymmetric-path bypass
set deviceconfig setting session tcp-reject-non-syn no
It was working fine then then i undo my change via
going to config mode
set deviceconfig setting tcp asymmetric-path drop
set deviceconfig setting session tcp-reject-non-syn yes
Since then i am able to access website fine
@MP18 sorry for the late!
Thanks for your update, Actually that was in data center firewall and it's in production so i am not sure can i make the changes, we are using 7 gateways on that firewall for global protect VPN, and that issue is only for VPN users
So please confirm whether can i make the changes or not,
As PA is dropping the syn ack from the server as it is taking too long.
See below link.
I had to make above change to make it work.
I will not recommend you above change as I do not know your environment.
For now their is no other way seems to access that website behind the PA firewall.
