We are running Palo Alto Global Protect with Symantec VIP MFA. We have run this for quite some time now and it has been stable until recently.
We are seeing random errors appearing on one of the validation servers. It seems Palo is sending the request but Symantec is dropping it. A restart of the validation service on VIP EG fix the issue temporarily but it appears atleast once a day everyday.
I have taken a wireshark capture when the error was happening. You can clearly see the firewall making the request with no response from the server and from packet 7527, this is where i restarted the validation service on Syamentec running on the port you can see response going to the firewall.
Understand this looks more like a Symantec issue but the change was made on the firewall which triggered these errors. On Palo i have started using Authentication sequence which goes through 3 profiles. 2 X LDAP and last one Radius. 1 x LDAP is not in use and i will be deleting that.
The radius one has been recently added using Okta MFA. Surprisingly when i remove the profile from the sequence on Palo no errors are seen on Symantec VIP MFA server. I have tested this a number of times now at the cost of some operational impact :(. No other way to reproduce the error. Ignore my feeble attempts to mask the IP.
Is the RADIUS profile going to Symantec VIP and then to OKTA MFA (please provide info how the RADIUS works and if you are making the SYMANTEC VIP to talk with OKTA ask Symantec if this is possible at all)? Why not directly integrate Okta MFA without RADIUS as this is supported by palo alto?
