Re: Unable to configure behind-NAT Fortigate IPsec VPN with GCP
Ok, same my scenario.
In our offices we had two type of routing:
- NATted Modem/router with virtualIP/Virtual Server: Fortigates are behind them, with WAN private IP
- Transparent LAN port on modem/router: Fortigates is connected to a physical LAN port on router and has public WAN IP.
If you can, you must set up a Transparent IP mode on one LAN port on modem/router where the public IP pass as-is.
In this case you must have one IP for the modem/router and one IP for the Fortigate, and each modem/router port must be set as interface instead of switch
Which modem/router do you have?
