multi wan with icmp

[crp]

Hi.

Is there a reason for the multiwan setup being put together with DNS (https://docs.opnsense.org/manual/how-tos/multiwan.html)?

My intention is to setup a multiwan environment using icmp only. Is that possible?

Thanks.

However, for the sole purpose of wan failover and load balancing, I've found that it is still not mature enough:

• the failover feature is tied to the use of DNS, and it will bring trouble if you want to use other features like DNS over HTTPS
  
• The stick connection works at host level instead of TCP/UDP level. The result is that the load balancing will only be achieved if you have many hosts

So, after some research, I am using VyOS for load balancing and failover of 2 WAN links from different ISP.

Thanks.
