DNS and/or DHCP Settings for Starlink as part of Multi-WAN

[AK_Astro]

Hello, I've been searching all over and trying to read guides but much of this is over my head.

I just got OPNSense up and running with multi-WAN failover for my home network yesterday. I have two ISPs/gateways coming into a mini-PC: Starlink and my failover old ISP with a hard data cap.

In reading many guides I'm seeing people needing to configure some specific DNS and DHCP settings to keep things happy based on some unique Starlink behavior but I'm not sure if any of it is actually needed or not, especially as part of a Multi-WAN.

I followed the OPNSense multi-WAN setup documentation to the letter and that seems to be functional for me at this point.

For reference, this is one of the guides that mentions some specific settings: https://matthias.guru/en/2021/12/13/starlink-mit-opnsense-pfsense-als-router/

Thanks! I'm brand new to all of this but glad to learn it.
