Configuring the B02 Branch Office appliance
In "Use Case 1", B02 is deployed in bridge/router mode. It is connected to the Data Center directly through the MPLS private network and over the Internet via one tunnel.
A second 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 WAN2 interface.
B02 is also connected to an external gateway as explained in Use Case 11.
