Hello everyone,

I'm new to setting up VPNs. I have pfSense installed on Azure VM and I'm trying to setup a site to site VPN connection between the pfSense (AzureVM) and my local server (RRAS). I have configured Site to Site IPSEC IKEV2. RRAS receive "Invalid payload received" and pfSense logs say:

Any ideas why I'm not able to connect?

1. no virtual IP found, sending INTERNAL_ADDRESS_FAILURE. From reading around this seems related to mobile configs but I'm not trying to connect mobile devices.
2. Could it be related to ESP protocol for which I have opened up port 50 on Azure NSG but Azure doesn't have something to specifically allow the protocol

I greatly appreciate any help. Have tried a lot of things and still no luck.

Thank you
