Newbie with basic questions

    Over a year ago I purchased 2 WRT54G routers with Tomato pre-installed.
    Using information I found by internet searches I was able to configure each router on separate networks at different locations. Everything works great on both of these systems. Unfortunately, I do not remember the steps I followed in setting them up.

    I have recently encouraged my friend to switch his router to this same setup. He has connected the Linksys router with pre-installed Tomato and he has done some basic configuration to the Tomato settings based on instructions I gave him over the telephone while looking at my own successful configuration. I believe all the settings in the Basic Network section are configured properly.

    After configuring these settings he is unable to connect to the internet with his browser. He has restarted all of the hardware. I've instructed him how I set up the "Static DNS" for OpenDNS. I believe he placed the proper addresses in the appropriate boxes for this. But perhaps this is the problem?

    He contacted his ISP support. The tech told him that he had the wrong MAC address entered in his router. He gave him the "correct" MAC address which he entered into the "WAN Port" box under the "MAC address" section. But this did not help.

    I am wondering if the problem is in the settings in the "Advanced/MAC address" section. I can't remember what I did in this section when I successfully set up my two systems. What is the proper procedure for determining what MAC address goes into the "WAN Port" box? Do we just click the "Default" button or is there unique specific MAC address that needs to go there? If so, how do I determine it?

    Would it be wise to just start over from scratch by doing the "Restore Default Configuration"? If so, which option would be best to choose-- "Restore Default Router settings" or "Erase all data in NVRAM memory".
    Any help would be greatly appreciated.

    This is not a lazy request for information. I have now spent several hours in the past 3 days Googling unsuccessfully to find answers.

    What kind of isp connection does your friend have? Cable modem, DSL etc?

    More info

    He has a wireless internet connection from Digis. This is the same ISP that is used by one of the networks I previously successfully set up with Linksys/Tomato. So I know it should be able to work if configured correctly. He has no trouble when he connects using his USR Robotics router.

    I have made screen shots of the major configuration settings for the system that works with his same ISP. I'm hoping that by examining the settings I may find a solution to his problem.

    How do I decide what value goes into the "WAN Port" box under "MAC address"?
    I think this may be the problem.

    You should not have to put anything but that actually is all dependent on his isp. Some isp lock down their connection to a single device. Long ago that was because they wanted you the end user to pay for more then 1 connection but with the advent of nat and home routers that has all but gone away. I leave the wan mac blank, reset the wireless device, let it boot up completely then reset the wrt. In most cases unless the isp is doing something goofy that should work. If that does not then log into the usr router and write down the mac it has for its wan interface. Input the usr mac into the wrt wan interface and have it mask that mac.

    Good information!

    Thank you, ifican

    Your explanation makes perfect sense. It really seems less complicated than I had expected it to be.

    I noticed on my home setup that the "WAN Port" MAC address is completely different from the MAC address on the back of my Linksys Router. None of the MAC addresses of any of my hardware corresponds to this number. I wondered where that MAC address came from. Now I'm thinking it may have been the MAC address of the old Netgear router that I used when I first signed up with Comcast.

    If I understand you correctly, changing the WAN Port MAC address in the Tomato configuration causes the ISP to think that that value actually represents the MAC address of that device.
    Thanks for your help.
    I'll report back after I get a chance to go to my friend's house and help him set things up.

    Thats correct, the upstream (isp side) device has no way of know what device is sending the mac it just knows what the mac its receiving is. From what it sounds like that should take care of it for you. Let us know when you get a chance.
