Have you ever tried to set up VLAN between a new router and an old one? You might or might not have noticed that the default VLAN is different on a model basis e.g.: ASUS AC56U has by default VLAN 1 and 2 Buffalo WHR-HP-G54 has by default VLAN 0 and 1 Incidentally I have and additional VLAN I use to transfer guest WLAN traffic as well. so it turns into 1-2-3 for new devices, 0-1-2 for old devices. You might think, never mind just change either and make them talking the same VLAN number... not quite! doing so after a reboot you get a real mess in the VLAN config page as tomato expects to have that first VLAN numbered that way it thinks, so it recreates it regardless adding all the LAN ports to it: What I want: What I get after a reboot: Unless I'm missing something, it sounds like a bug to me. Thoughts?
