Multi-WAN with Backup down

[luckyh_de]

Hi Folks
I have a Multi wann Setup we're i need the Second-Link down until primary fails.
Reason for that:
The primary Link ist my DSL Connection
The secondary Link ist connected to an LTE-router with a Plan "pay per use"
So i have to prevent any Packet to the LTE-router AS Long as primary ist okay
Only If primary fails the IP Interface should bei brought Up and provide connectivity.
A Setup which Monitors the second Link is No good cause IT leads to "costs"...

Hi,

The failover mechanism does not allow this, you definitely need something that, which tells the firewall that the connections are alive
(minimum GW pinger ICMP traffic)
