    I want to only enable one of the ethernet jacks on router. To prevent casual connection hijacking on the router, is this possible? Using standard tomato firmware and the router is a WHR-HP-G54.

    It's not disabling, but move the ports to another VLAN which has no access to the other VLANs.

    Actually, you shouldn't even need to define another VLAN. Simply take those ports out of the existing bridged VLAN.

    I'm not sure what the VLAN setup is on the WHR-HP-G54, but go to the command prompt and look at nvram variables "vlan0ports", "vlan1ports" and "vlan2ports". Only two of those three should actually be defined. One of them should have 5 values and the other should have 2 values, where one value is in common between them. On the vlan*ports variable that has 5 values, remove 3 of them THAT AREN'T THE COMMON VALUE. You may also have to set the variable "manual_boot_nv" to 1 to prevent the boot process from resetting to the default values.

    Yup, this is a good solution. I also used it to change my WAN port to LAN port at one point in time. :)
