We have configured Radius on our VM Palo but its not working. Provided screenshots of configuration we have on the FW and output of test command. Routing is defiantly in place as we can ping Radius server, however no traffic on 1812 reaching PacketFence Radius server. When done tcp dump - I can clearly see it's capturing pings but nothing for port 1812.
Palo Support not being helpful as for now just keep sending me unrelated articles... So hopefully get some advice here 🙂
Target vsys is not specified, user '*******' is assumed to be configured with a shared auth profile.
Egress: x.x.208.14
Authentication to RADIUS server at x.x.65.40:1812 for user '*******'
Authentication type: PAP
Now send request to remote server ...
RADIUS error: bind: Cannot assign requested address
Authentication failed against RADIUS server at x.x.65.40:1812 for user '*********'
Authentication failed for user '****'

Do you see auth attempts in logs? What is in log description?
By default traffic sourced from Palo goes out from mgmt interface.
Assuming radius server IP is 1.2.3.4 does command "ping host 1.2.3.4" get replies?
Is Palo mgmt interface and radius server in same subnet or does this traffic traverse firewall?
If it traverses firewall do you see those sessions in traffic log?

ping is going through to radius - I have even add "source" in command to be sure is coming out of management interface.
We can see Auth logs as well but obviously not succesfull :
( description contains 'failed authentication for user \'*****\'. Reason: Authentication request is timed out. auth profile \'PF-Radius\', vsys \'shared\', server profile \'PF-Radius\', server address \'x.x.65.40\', auth protocol \'PAP\', From: x.x.x.x' )

If this traffic traverses firewall you can check Monitor > Logs > Traffic if those sessions are permitted, and if packets are sent and received.
You can also take packet capture https://docs.paloaltonetworks.com/pan-os/9-1/pan-os-admin/monitoring/take-packet-captures/take-a-pac...

Yep, we have checked monitor and no intersting traffic was there. Will try to setup capture to see it there. Just wondering if tcp dump from command line is sufficient an that was already done - we could see ping to radius server but nothing on 1812.
