When this happens, existing connections continue to work without issue in most cases. In fact, for most deployments the public IP address for the VPN server resides not on the VPN server, but on an edge firewall or load balancer connected directly to the Internet. When troubleshooting these issues, the common denominator seems to be the use of Full NAT, which includes translating the source address in addition to the destination.

Full NAT may be explicitly configured by an administrator, or in the case of many load balancers, configured implicitly because the load balancer is effectively proxying the connection.

When this happens, clients connecting using IKEv2 may fail to connect, most commonly when the server is under moderate to heavy load.

The way to resolve this issue is to ensure that any load balancers or NAT devices are not translating the source address but are performing destination NAT only. Expand Standard Options and select Transparency. Making the changes above may introduce routing issues in your environment. If this is not possible, consider implementing the workaround below. Be advised this is only a partial workaround and may not fully eliminate failed IKEv2 connections.

Got it. Despite having direct NAT? Potentially, yes. Hi Richard, thank you so much for posting this. This issue caused me a great deal of trouble when initially setting up AOVPN behind our F5 load balancer and I now have an explanation as to why, where before I had none.

Thanks for the post, Richard. Another timely article for sure. I see in some cases where during the ISAKMP negotiation the server is unable to send the server certificate back to the client and complete the negotiation. This results in a event ID and the server gives up trying after about the 3rd attempt. This is rare, however.
