I've seen a number of examples of how to route traffic to a cable modem web UI when it's on a different subnet than the DHCP network it is providing, and that works fine for me.
The troube is, I have the same type of setup on my 5G failover modem, which I don't want to pass traffic across unless the cable modem circuit is down, and I'm struggling to find the right way to configure each of the interfaces so I can route traffic to the respective web UIs, but have the internet connection properly identified as up or down, and have the secondary link only pass any traffic in a failver scenario.
Does anyone have any posts, documentation, or other pointers I can look at for how to most effectively set this up?
Thanks.
I followed this and mine works perfectly.

Thanks. I've got the failover working just fine though, which is what this guide covers.
What's not working is when gateway 1 is active I can't get to the web UI on gateway 2, and vice versa. If I'm on the failover gateway I'd like to be able to look at the web UI for gateway 1 to see what's up with the link, but I'm stuck on being able to see the web UI on gateway 2 only.
I know there'll be a way to do this. I just can't figure out what the neatest way of doing it is.
