If you're routing traffic inbound and performing NAT at or behind the VPN server, then you must open your firewall rules to allow UDP ports 500 and 4500 inbound to the external IP address applied to the public interface on the VPN server. Redirect Universal Datagram Protocol (UDP) ports 500 and 4500 to the VPN server. Configure routing so that the DNS servers and VPN servers can reach the Internet. This deployment uses IKEv2 and Network Address Translation (NAT). Make sure that the VPN server can reach all of the required internal networks and network resources. If two vpn routers are behind a nat device or either one of them, then you will need to do NAT traversal which uses port 4500 to successfully establish the complete IPEC tunnel over NAT devices. pantelis1 Edited by Admin February 16, 2020 at 2:30 AM

First thing you need to make sure is you have the following command :. crypto ipsec nat-transparency udp-encapsulation. Secondly, make sure the other router ahead of this device is doing one to one nat for this IP. As long as crypto map is applied to correct interface, we should see correct UDP port.. If this does not help, can you please share complete debugs (do sanitize the IPs accordingly VPN and Port Forwarding of UDP 4500 - Cisco Community

When a user starts a Mobile VPN with IKEv2 connection: The VPN client starts a connection on port UDP 500. If that port is not open on the client gateway, the session does not proceed.
