IPsec VPN - Starlink to Fortigate

[denji0]

Hi.

The staff member of a client of ours who has a 60E Fortigate with the latest 6.2 firmware, is trying to connect from his new home, which uses a Starlink connection. If we use the Starlink connection, we cannot connect at all to the Fortigate, but if we tether to a Mobile 4G connection or similar, it works fine, as does the same credentials from a Fibre connection.

TIA for any insight into what might be happening.

Are you able to ping the Fortigate interface via starlink?

Hello,

The issue with the Fortigate not working when connecting via a Starlink connection probably related to connectivity issues through your ISP.

Please attempt to ping the firewall's public interface using the Starlink ISP, then verify on the FortiGate whether you are getting traffic from the client workstation.

Hi,

Since you are able to connect to the Fortigate using your Mobile 4G connection, I suspect the issue to be with your Starlink. To siolate the issue, you could try to ping the firewalls interface with your Starlink ISP and see if packets are reaching the Fortigate. You could use the command:

diag sniffer packet any 'host <your Starlink Public IP and icmp" 4 0 a
and initiate the ping from your PC connected to Starlink ISP. If you don't see packets at all on the Fortigate, it will be an issue with the ISP.
