There is a lot of information regarding configuring a Linux server as an endpoint for an Azure VPN. However all of these appear to be related to statically routed VPNs.
It seems that dynamically routed VPNs use IKEv2/IPSEC Openswan supports IKEv1 Strongswan appears to support IKEv2 but I have been unable to get it to work so far.
So my first question is simply, has anyone been able to configure a Site to Site VPN using dynamic routing into a Linux Server.
