I am struggling to get a VLAN working over a VPN to a FortiNet router.
I’ve setup an IPSec VPN to the FortiNet which is showing up from both sides.
I’ve created a VLAN 100
I’ve created an interface called VPN with 10.1.X.X/24 range on and assigned it to eth0.100
On the Interface > General where I’ve created one called VPN with the 10.1.X.X, I’ve not put a gateway in. Does there need to be one? Is this the internal IP of the other side of the VPN?
I’ve also allowed the VPN to access all areas on the firewall and turned the Local Firewall off on the VPN.
Could you please clarify what exactly is not working? Are you unable to establish an IPSec connection or does the connection establish, but you are unable to reach devices over IPSec?
Could you please share screenshots of your configurations? Before doing so, please hide/blur any sensitive information that may potentially be visible on the screenshots, such as Serial Numbers, public IP addresses, etc.
It would also be great if you could include IPSec logs that can be found in the system logs. System logs can be accessed in System → Maintenance → Troubleshoot → Show System logs.
I don’t have those options for System logs on mine, the logs I did find, none were showing IPSec. But the connection is showing up when i do an “ipsec status”.
