Multicast IPsec VPN without PIM
This is an example of allowing transparent multicast communication between two networks located behind FortiGates connected via IPsec VPN. Multicast is configured to send traffic across the IPsec tunnel without the use of protocol-independent multicast (PIM) or other multicast routing protocols. Two hosts are used to send and receive a multicast stream between the two sites. In this example, the FortiGate with the multicast streaming server is HQ while the FortiGate with the multicast client is Branch.
