This should really be noted as a bug and the change be implemented into NethServer. I’ve been doing some testing today with WAN failover and it was taking so long to fail over and fail back that it was pretty much useless. After changing interval_ms and timeout_ms to 100, it took a reasonable amount of time to fail over and fail back (10-15 seconds).
Edit: The more testing I do, the more I think the options for probing/check ip should be custom configurable. In my experience with enterprise hardware, there’s usually two options for failover:
- how often to ping
- how many failed pings before failover
…and two options for failback:
- how often to ping
- how many successful pings before failback
Being able to customize those settings under ‘advanced’ options for multi wan would be absolutely amazing!
