Having trouble with EdgeOS Loadbalancing

[RaddedMC]

Hey LTT!

I'm trying to set my EdgeRouter X to segregate my network to the following:

I have two WAN's: a 25 Mbps DHCP connection and a 1.5 Mbps PPPoE connection (I know it's really old, we're in the middle of nowhere)

We're trying to set the router up so that all devices on it get the slower connection other than a few 'promoted' devices which get both the 25 and 1.5 lines with load balancing (25 has only 1.5 Mbps upload and 1.5 has 0.5 upload so we're trying to obtain more overall upload bandwidth), with failovers when one connection fails.

Currently I have the following settings:

firewall {
  group {
    address-group {
      GOD_TIER {
        ~~promoted IP's here~~
      }
    }

  modify {
    balance {
      rule {
        10 {
          destination {
          	network-group = PRIVATE_NETS
          }
          modify {
          	table = main
          }
        }

        20 {
          destination {
          	address-group = ADDRv4_eth0
          }
          modify {
          	table = main
          }
        }

        30 {
          destination {
          	address-group = ADDRv4_pppoe1
          }
          modify {
          	table = main
          }
        }

        41 {
          destination {
          	address-group = GOD_TIER
          }
          modify {
          	lb-group = G
          }
        }

        42 {
          destination {
          	address-group = PRIVATE_NETS
          }
          modify {
          	lb-group = B
          }
        }

        50 {
          modify {
          	table = main
          }
        }
      }
    }
  }
}

interfaces {
  switch {
    switch0 {
      firewall {
        in {
          modify = balance
        }
      }
    }
  }
}

load-balance {
  group {
  	G {
      interface {
      
      	pppoe1
        eth0
        
      }
    B {
      interface {

        pppoe1

      }
    }
  }
}

Plus other defaults from the load-balancing 1 wizard

 

What I expect to happen is that when one device is removed from the GOD_TIER list it only gets internet access from pppoe1 but what actually happens is that no matter whether a device is added to the GOD_TIER or not it uses the G load-balance group. If I remove eth0 from that group then the entire network is restricted to only pppoe1. Does anyone have any suggestions? Thx!
