I had my Asus 520GU running Tomato for about 3 days now (first plain 1.25 and then switched to Teddy Bear's mod v35) and it generates traffic for no apparent reason (see attached graphs). I've used the router to download 1gb worth of files around 4pm but before that, I only browsed internet, checked email and stuff at 9-10am, 12-1pm and 3-4pm. The rest of the time my computers were off or sleeping. Wireless is disabled. As you can see, Vlan1 which supposed to measure traffic coming into and out of WAN port on the router, shows up ~6.5gb of data. Vlan0 which shows internal LAN ports, shows only 1gb or so. Can anyone tell me, what is going on here? I don't understand it, is that real traffic or some sort of glitch in Tomato programming or 520gu hardware? What kind I do to track down the source of the problem? Update: I've stuck the router behind one of my computers with lan ports, so it's like that: ISP --> computer with shared LAN --> router --> laptop 1hour and so far, doesn't seem to generate any traffic... So, my guess is - the Tomato is interacting with ISP switch or something... What might be the cause of that, can someone offer a guess?
