Configuring the B02 Branch Office appliance
In "Use Case 2", B02 is connected to the Data Center through two tunnels, one over the Internet and the other one over the MPLS private network.
A third tunnel connects B02 to B01. For this reason, Port Forwarding must have been configured on the Internet Access router. This rule authorizes sending the UDP packets to the appliance on ports 500 (IKEv2) and 4500 (IPsec NAT Traversal). You must apply a static IP address to the B02 WAN1 interface.
