for one of my customer we will need 3-4 parallel Encrypted IPSEC tunnels per ZEN. Or documentation describes only one tunnel per ZEN. Has someone a tested config to 2 or more tunnels in parallel?
Are there any known issues in such a case?
For your single public IP, there will be two tunnels towards ZEN1 and ZEN2.
If you have multiple public IPs on the same location, you can create multiple tunnels towards ZEN1 and ZEN2.
Example : If you have two ISP on your infra, then you can build 4 tunnels , 2 to ZEN1 and 2 to ZEN2.
I was tested this scenario and load balancing as well.
