Two Starlinks, one always down?
«

On my Opnsense appliance (DEC2770) I have two Starlink HP dishes connected. The intention is to failover/load balance across them.
Both interfaces (Starlink1 and Starlink2) have been identically configured:
Enabled
Block private networks: True
Block bogon networks: True
IPv4 Configuration Type: DHCP
IPv6 Configuration Type: None
Everything else default or empty
In the interface assignments:
Starlink1 -> wan -> igc3
Starlink2 -> opt15 -> igc4
In System > Configuration > Gateways I configured monitor ips (8.8.8.8, 8.8.4.4 (but I've also tried with 1.1.1.1)), but have also (like in the screenshot) left it empty so it uses the gateway as the monitor IP. But, the one gateway always seems to be down.
Why? Did I miss something?

Both connection use the same gateway. It will not going to work this way.
Maybe you can request to get a different one for one of your MACs.

Starlink doesn't support this unfortunately. The only option you have (with the right plan) is to switch between "Default" and "Public" IP addresses. Even when switching both to the public IP option, both were given an IP (200.x.y.a/b) that still had the same gateway.
Do I need an additional router for each of these Starlinks to maybe to some NATing?

At least one.
You have to achieve that you have different gateway IPs for the upstream connections on OPNsense. So it will be sufficient if you insert a router in one of them and use its local IP as gateway.

Well, I'm going to end up with 3 x Starlinks, so to keep it succinct I'll just get 3 small routers.

you may be able to set up two different OPNsense and possibly use CARP to use Active Passive.
