Linksys WRT54GL and Tomato for a newbie?

Discussion in 'Tomato Firmware' started by FattysGoneWild, Apr 3, 2009.

    Here is the deal. Firstly. I am on cable internet. I have always used a wired connection. I know nothing about wireless at all. Reason why I am wanting to go wireless. I want to free up a couple 50ft ethernet wires. Here is how my network currently looks.

    Linksys CM100 cable modem
    Linksys BEFSR41 V4.0 with latest firmware


    Desktop (main pc using DHCP)
    Netbook (DHCP)
    Nintendo Wii (static ip and using port forwarding)
    Xbox 360 (static ip and using port forwarding)
    Directv for on demand (DHCP)

    The Netbook and Nintendo Wii would be the 2 going online wireless. Is running Tomato idiot proof? I have been reading on this before making a purchase. The info is over whelming. So much to learn. Any tips/suggestions would be great. As far as flashing with Tomato. I believe it goes like this from reading online.

    1. Hook up cable from pc to port 1 on router.
    2. Log in and set every thing to defaults
    3. Log back in and flash with Tomato
    4. After the flash is done. Continue and close browser
    5. Hold reset button for 30 seconds and log back in
    6. Configure to my needs
    7. Shut down pc and hook things up to go online

    Is that all right?

    Also. For the gaming systems. If I assign them with static ip's. Will the NAT be Open? Currently I am having to use port forwarding with my router. Since UPnP and DMZ does not work properly. And 1 last thing. When installing the firmware and it is finished. Does it match the default settings of the Linksys firmware?

    Is Tomato idiot-proof? No, it's not, but its interface is set up more logically and clearly than any other firmware GUI I've seen, so I would say it's closer to be idiot-proof than the rest.

    I think you've basically got the flashing steps right.

    No, setting up static DHCP leases for clients on your network has nothing to do with open NAT'ing or DMZ'ing.

    Yes, port forwarding, by way of the traditional, open port forwards or by UPnP/NAT-PMP protocols is much preferred to putting a device in the DMZ (unless said device is a public web server). What problems, specifically, were you having with port fowards on your current setup?

    I don't believe I would say the default Tomato settings match those of the default Linksys firmware's, unless you just mean WAN connection is set to Type - DHCP and the switch ports are set to hand out DHCP leases in the range, then yes.

    1. Basically I could not get a open nat no matter what. I tried UPnP, DMZ, static ip etc. The only thing that worked was port forwarding to get the nat open for the gaming consoles. For security purposes. I really wanted to avoid using UPnP. So, I was hoping the WRT54GL out of the box was open nat friendly for gaming consoles when using a static ip with them. Do you or any one else know for sure if this router makes the nat open for gaming consoles when just using a static ip for them?

    2. That is pretty much what I meant. Sorry I should have been more specific. That way I can keep my gaming consoles at the current static ips.

    Maybe I've misunderstood you. What do you mean when you say "...I could not get a open nat no matter what"?

    Are you talking about Xbox Live? If so, are you sure you're not doubled NAT'd? That is to say, your cable/DSL modem is performing NAT'ing/firewalling in addition to your WRT54GL behind it?

    Because I've been using Tomato'd and DD-WRT WRT54G-series routers for years with all sorts of gaming, lots of Xbox Live, and I've never had a problem getting them to work properly, whether through UPnP, static port forwards, triggered port forwards, etc.

    Out of the box Tomato will hand out DHCP'd leases to all your LAN hosts until you set them up for static DHCP leases. Tomato makes this easier than any firmware I've seen. Just point and click.

    My current router a Linksys BEFSR41 V4.0 latest firmware. With Xbox live. Games would come up with a NAT error and when running the live test. My nat would show as strict/moderate. With port forwarding enabled. I got it to be open that way. Same with the Wii. No double nat. The modem is its own and so is the router. I just pulled the trigger on the WRT54GL last night through newegg.com Should be here Monday or Tuesday. As I said before. That is why I was really hoping the WRT54GL would be open nat friendly just using static ip's for the consoles. That way I would not have to use UPnP, DMZ, port forwarding etc. What do you advise in my case with the game consoles? Thanks again for the help/input. Appreciate it.

    Well, you misunderstand how Xbox Live works. Xbox live needs these ports open:
    TCP 80
    UDP 88
    UDP 3074
    TCP 3074
    UDP 53
    TCP 53

    Now, this can be done in these ways, in order of preference: 1) UPnP service that automatically opens the ports on the router only when your Xbox requests it, 2) static port forwards in a port forward table that are open all the time, leaving you slightly more vulnerable and 3) putting your Xbox console in the DMZ, which would be the most susceptible to hackers (however unlikely).

    Tomato can do any of these things, and with the UPnP method, my Xbox 360 has always achieved Open NAT on the Xbox Live test.

    And, once again, static DHCP leases have nothing whatsoever to do with how your ports are forwarded.

    Here's MS' KB article on it: http://support.microsoft.com/kb/908874

    Thanks. I will enable UPnP and hope for the best with both consoles. Would make life much more easier.

    I can tell you I have first-hand experience with three Tomato'd routers working perfectly with Xbox Live, so...yeah, it works, dude...don't worry about it :)

    1 last question before doing the upgrade. I noticed in the FAQ it says the following.

    If using a 10/100-network adapter, change its speed to 10Mb, half duplex.

    Did you guys change it to that before flashing the firmware? My adapter is currently set to 100Mbps/Full Duplex

    Never noticed that, never paid it any attention. My guess would be that it's just old, outdated info and you don't need to worry about it.

    I went ahead with the flash and it has been fantastic! Every thing just works. My only snag was the consoles old settings. I have them manually set up under network settings. For my old router would work with port forwarding. Set it back to Automatic and things are running great with the consoles. It is nice not having to do the extra work. Thanks again for all the help/replies bripab007. Really appreciate it. Few more questions.

    Receive Antenna: Auto
    Transmit Antenna: Auto
    Transmit Power: 42

    Any benefit changing those options? Any more tips/suggestions to change any thing from default settings? I am on cable internet.

    Should I change the following from default:

    Receive Antenna: Auto
    Transmit Antenna: Auto

    To this:

    Receive Antenna: A
    Transmit Antenna: A

    I noticed on Wiki it says the following:

    # Receive Antenna: Selects which antenna is used for receiving. These settings are primarily useful for external antennas. Single antenna units should be set to Auto.

    # Transmit Antenna: Selects which antenna is used for transmitting.

    Not sure what they really mean though.
