    I am trying to understand how all the RX/TX transferred numbers add up and what the interface is. It seems like things are not making sense to me. See my comments in parenthesis.

    br0 (Bridges eth0 Vlan1 tap22, *should* have the sum of all internet traffic)
    RX bytes:17764220816 (16.5 GiB) TX bytes:96442932561 (89.8 GiB)

    eth0 (This is the wan port, why is the RX/TX so low?)
    RX bytes:675754452 (644.4 MiB) TX bytes:1046435312 (997.9 MiB)

    eth1 (This is 2.4ghz wifi)
    RX bytes:1428839697 (1.3 GiB) TX bytes:2057237013 (1.9 GiB)

    eth2 (This is 5ghz wifi)
    RX bytes:0 (0.0 B) TX bytes:252914164 (241.1 MiB)

    fwd1 (NO CLUE what this is, is it related to lo for adblock or pixelserv)
    RX bytes:0 (0.0 B) TX bytes:984779139 (939.1 MiB)

    lo (loop back, and it has 346MB of traffic which was sent to it for adblock/pixelserv)
    RX bytes:363956695 (347.0 MiB) TX bytes:363956695 (347.0 MiB)

    tap22 (vpn tab interface)
    RX bytes:31093507 (29.6 MiB) TX bytes:713780026 (680.7 MiB)

    tun21 (vpn tun interface)
    RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

    vlan1 (I am assuming this is for the first 4 ports in switch ac88u, the 309/21GB is for all switch traffic?)
    RX bytes:22904673517 (21.3 GiB) TX bytes:332594074480 (309.7 GiB)

    vlan2 (tools page shows its connect to wan port, but no traffic here, any reason?)
    RX bytes:0 (0.0 B) TX bytes:424 (424.0 B)

    Are my comments correct? Can my questions be answered, please. I am trying to better understand all these.

    It's important to realise that if you have hardware acceleration enabled the amount of data transferred between the WAN and the LAN interfaces is not counted. This is because it bypasses the normal network stack, so ifconfig will never return meaningful information.

    Thanks for bringing this up, I have it disabled as my internet speed is not fast enough to benefit from it.
