When you for example set an url-category into "continue" the continue response-page is issued through tcp 6079.
However there is no need to setup a policy for this traffic since the PAN will handle this on its own.
But when I enabled captive portal with ntlm-auth I noticed blocked traffic towards the L3 interface of the PAN at tcp 6080 and 7080.
What are these ports used for and does there exist a portlist for which ports one might need to create policies for to avoid denied/dropped packets (which I assume shouldnt be denied/dropped)?
Port 6080 is used for captive-portal authentication, this is a web page prompting the unknown user to login via username/pwd.
Port 7080 is used for NTLM authentication, this is simulating a Windows server authenticating the unknown user to login via NTLM username/pwd.
The PAN device uses these ports to decide which authentication method to use to challenge the user. Some addt'l services may also be in used depending on the configuration:
for mgmt: HTTP, HTTPS, telnet, ssh, ping, SNMP
PAN agent: a configurable TCP port like 3011
TS Agent port
SSL, IPsec ports for VPN
