Review the SKUs noted in the documentation for gateway:
Basic SKU- Max 10 tunnels, others max 30. 
VPNGw1,2,3 support P2S IKEv2 connection and BGP and each have bandwidth higher then the last.

Azure - Check Invitation Status to guest user

-
Image
Often times you will need to invite a 3rd party to your Azure AD tenant to support your environment. When you add them to a resource, they will automatically be invited as a guest user in your Azure AD tenant, however they won't be able to access this until they accept the invitation email. If you send an invite to a guest user you can see if they have accepted the invitation or not. You also have the option to resend the invitation. From Azure AD you can search for guest users and drill down into an individual one. Here is what the email looks like - the key here is the email comes from " [email protected] " because it can be sent on behalf of this may end up in the junk or spam email folder, so be sure to have them check there.

This could be because one of the network devices (e.g, firewalls, NAT, routers, etc) between your computer and the remote server is not configured to allow VPN connections. Please contact your Administrator or your service provider to determine which device may be causing the problem. (Error 809) The strange thing was that some other workstations seemed fine. After bashing our collective heads against the wall, checking checking the P2SChild, doing all sorts of network troubleshooting to the endpoint DNS name -  azuregateway-8fc2c9e3-26cd-432a-ae47-92b7f6422a5d-e1a7e8cec41d.vpn.azure.com , editing registry, checking firewalls, etc, we finally determined the caus
