MNHA: Active-active Mode (SRG1+)

You can operate Multinode High Availability in active-active mode on supported firewalls. Multinode High Availability supports IPsec VPN in active-active mode with multiple SRGs (SRG1+). In this mode, you can establish multiple active tunnels from both the nodes, based on SRG activeness. Since different SRGs can be active on different nodes, tunnels belonging to these SRGs come up on both nodes independently. Having active tunnels on both the nodes enables encrypting/decrypting data traffic on both the nodes resulting in efficient use of bandwidth.
