fortigate firewall suddenly not working with cisco ise as Radius server

Hello,

I am facing an issue with fortigate firewall in cluster a-p, both are integrated with cisco ise working as Radius server.

Suddenly, we are seeing that Radius settings for ISE is failed; saying " can't contact radius server"

Fortigate version is 7.2.4

however, there is another set of FGT firewalls which are working fine.

Only difference is that these firewalls are in DMZ and ISE is behind mgmt firewalls which are working fine. So DMZ Fws talk via transit vlan.

@funkylicious , today the issue was resolved after enabling the ha-direct settings in HA settings.

Hi Zayd

Does the second firewall have the same FOS (7.2.4)?

Can you confirm if the RADIUS request reaches ISE?

You need to make sure RADIUS request from FG properly reach ISE.

E.g. if there is a firewall between them you need to allow the related traffic.
