Hello I am having issues setting up the Azure VPN tunnel from my fortigate to my Azure Network. Keep in mind i am not great with networking, i have a very basic surface level understanding of all this.
Note : The tunnel on the FortiGate is UP, it shows as Connected in Azure under my connections. Although there seems to be no traffic passing at all.
Network setup :
Internet → Fizz Router → FortiGate → Laptop I’m trying to domain join via the Gate
The Fizz router has IPsec passthrough enabled, it also has ports 500 and 4500 configured in port forwarding. I am not sure if i need to create a static route on my Fizz router to enable the traffic.
WAN port from the fortigate is connected to Fizz router and is receiving IP 192.168.0.13 | My LAN ports on the fortigate are configured to 10.1.3.1/255.255.255.0
I know that the virtual gateway in azure works because there are 2 other connections in the azure portal showing as connected. Created a seperate local network gateway with address space 10.1.3.0/24 with an FQDN that points to the public IP address of my fizz router. (Not the Fortigate)
I double checked the encryption settings on for the fortigate to match the settings on Azure and they both look good. I also made sure i have my static route set on my fortigate to point to the address range of the Azure network.
Im not sure where to go from here to proceed. Do i need to create a static route on my fizz router to point to the virtual gateway since it is in front of my fortigate ? If so what destination IP and Gateway IP do i need to provide ?
Im sure im missing something somewhere as the tunnel shows up and working, but no succesful traffic.
Thank you to anyone who is able to point me in the right direction.
