F1000 and Huawei USG6620 to configure ikev2 IPsec VPN case

Network Topology：

The customer headquarters uses Huawei USG6620 firewall devices, and the branch uses H3C F1000 firewalls. An ipsec tunnel is established between the headquarters and the branch.

How to complete the ipsec vpn configuration with huawei firewall device.

1.The ipsec of the firewall equipment in the headquarters uses IKEv2 to establish an IPsec tunnel to protect IPv4 packets. Therefore, the branch equipment needs to use IKEv2 to establish an IPsec tunnel synchronously.

2.The egress IP address of the branch firewall F1000 is dynamically obtained by dhcp, and the IP address is not fixed. Therefore, the branch device needs to use the local identity of the FQDN (Fully Qualified Domain Name) type.

3.In order to avoid the ipsec interest flow being converted by nat, it is necessary to remove the ipsec interest flow in the rule of NAT ACL.
