Block FortiSASE Access on corporate connection.

Hi,

 

We want to block the connection of FortiClient on FortiSASE by blocking it on our corporate firewalls. 

We already use the IP addresses of provisioned Security POPs on the FortiSASE instance, but still did not work. So we try to use Wireshark to check the connection and got the IP address of 154.52.16.101. We check the equivalent IPs and got the IP ranges, just to make sure, we want to ask if is there an equivalent IPs to this and if it has specific hostname on this IPs.

Thank you.

Hi,

 

- Are you using a dedicated public IP for your FortiSASE instance? 

- We can usually block the communication using threat feed. 
https://docs.fortinet.com/document/fortisase/latest/administration-guide/751044/appendix-a-fortisase...
- However I don't see the mentioned IP in the threat feed. 

- Another way is to configure the profile in the SASE portal using "Bypass SASE" option. If your public IP of the clients behind the firewall is a specific one then it can be bypassed to connect to SASE.
