We have 2 virtual fortigates - one is deployed in Azure environment, second in our local datacenter on ESXi infrastructure. On these 2 fortigates we have installed trial licenses (provided by vendor). We have configured IPsec over GRE between these 2 fortigates. Connection is stable but speed is very low, maximum in peak was 15 mbp\s. Not sure there is the problem..
