    Wireless Ethernet Bridge Mode - [WEBM]


    At the risk of sounding redundant, Wireless Ethernet Bridge Mode [WEBM] is just like Wireless Client Mode [WCM], except that the clients/computers/devices are a bridged to the host. In Wireless Ethernet Bridged Mode, your clients/computers/devices think they are connected directly to the host router [AP]. They receive their IP addresses from the host router [AP]. The client router Wireless Ethernet Bridge [WEB] is a transparent intermediary… ;^)


    This saves on wiring installs, no holes in the walls inside or outside, less copper resources are need, etc...



    Its the GREEN thing to do!!!:biggrin:


    N.B. = Nota Bena [Note Well for you :thumbup: non-Latin types]


    Setting up the Wireless Ethernet Bridge Mode…


    First… The ISP Service!!!
    Here is my setup…

    My ISP is Verizon FIOS…

    They supplied a Fiber Connection to my house and also provide a COAX feed to their Router and Access Point… Sometimes they supply a ETHERNET feed, depends on the FIOS installer... ;-) This will also work using ADSL, DSL, etc...

    I turned OFF the Wireless Radio… We want to control the wireless from the Tomato firmware router don't we now!!!

    I left it at the default settings…
    STATIC Router IP… 192.168.1.1
    Subnet… 255.255.255.0
    Gateway… 192.168.1.1
    DNS supplied by Verizon FIOS… 68.238.64.12, 68.238.96.12


    Under the Firewall settings… Minimum Security (Low) is used… Allows everything to go thru!!!

    Then I setup a DMZ IP of… 192.168.1.10
    This allows complete access to the Internet on the LAN side of this router!!!
    You will see how we use this IP below… ;^)

    Second… The House Router & Access Point [AP]

    I’m using a Linksys WRT54G-TM as the House Router & Access Point [AP]
    Using Tomato by Victek - Tomato Firmware v1.23.8515.5 RAF ND
    I have not upgraded yet to the latest yet, but this should work with latest firmware any way!!!

    I setup the following for the House Router & Access Point [AP]
    I connect to the WRT54G-TM on IP http://192.168.100.1/


    Using your Username & Password…


    Lets login… http://192.168.1.1/ for your router!!!


    This was on IP 192.168.1.1 the default IP of Tomato Firmware.
    I changed it to... 192.168.100.1
    It will come apparent why I used this IP see below...


    Click on the BASIC tab… Then Click on NETWORK page tab…

    WAN / Internet


    Type… STATIC
    IP Address… 192.168.1.10 This is the DMZ IP of the Verizon FIOS Router
    Subnet Mask… 255.255.255.0 This is the Subnet Mask of the Verizon FIOS Router
    Gateway… 192.168.1.1 This is the Gateway of the Verizon FIOS Router
    MTU… 1500

    Click "Save" at the bottom of the page to trigger the new settings. Tomato will restart.


    LAN


    Router IP Address… 192.168.100.1
    Subnet Mask… 255.255.255.0

    Static DNS #1… 208.67.222.222 I use OpenDNS.Com for my DNS servers!!!
    Static DNS #2… 208.67.220.220 I use OpenDNS.Com for my DNS servers!!!
    Static DNS #3… 0.0.0.0


    N.B. #1 - Using this setup we bypass the DNS servers of the ISP Verizon FIOS router & Access Point and one less hoop in the chase!!!

    N.B. #2 - You can use the DNS servers of your ISP here if do not want to use OpenDNS.Com or some other DNS provider. OpenDNS.Com servers respond quickly, most ISP DNS servers are mostly over whem with traffic!!! I.E. you will have quicker internet address resolving and better network protection using outside DNS provider!!!

    N.B. #3 -You can also specify in you TCP/IP settings of your device manually if do not want to use the ISP provider, OpenDNS.Com, or some other DNS server/s or provider.

    N.B. #4 -Your Router will have DNS Relay Server on IP 192.168.100.1 This will automatically relay DNS request's to what ever you specified for House Router & Access point [AP] to use.

    DHCP Server YES, make sure it is checked.


    IP Address Range… 192.168.100.100 thru 192.168.100.149
    This gives us 50 clients/computers/devices

    Lease Time… 8640 minutes
    [about 6 days] Less Time Management for the router to handle too.

    Click "Save" at the bottom of the page to trigger the new settings. Tomato will restart.

    WIRELESS


    Enable it!!!
    Wireless Mode Access Point [AP]

    B/G Mode… MIXED
    SSID… ABC123XYZ
    Select or Use whatever name you wish. SSID can have a period in it if you wish…
    Example… ABC123.XYZ

    SCAN for the best wireless channel to use!!! I use channel #7 with no issues, my neighborhood has lot's of user's on 1,6, & 11

    Broadcast… Yes or No
    Yes… Let’s clients/computers/devices see it!!!

    No… Shows up as a blank no name [AP]

    Security… WEP Some have had luck using other selections, for this topic we will use WEP
    Encryption… 128bits
    Passphrase…. Use whatever name you wish… The more characters you use the better!!!
    Generate your keys… There should be [4] four of them!!! SELECT the Key you will be using, for this topic will use # 1

    Click "Save" at the bottom of the page to trigger the new settings. Tomato will restart.

    Copy and paste the Keys all [4] four of them, SSID, Passphrase, Wireless Channel you are using into a document and save them on your computer!!!

    We will be using them for the Wireless Ethernet Bridge Mode [WEBM] and your clients/computers/devices.

    The House Router & Access Point [AP] now is the... MASTER FIREWALL DEVICE!!!


    Third… The Wireless Ethernet Bridge [WEBM]

    I’m using a Linksys WRT54G-V2 [4] four of them in the Wireless Ethernet Bridge Mode [WEBM]
    Using Tomato by Victek - Tomato Firmware v1.23.8515.5 RAF ND
    I have not upgraded yet to the latest yet, but this should work with latest firmware any way!!!


    N.B. - Using this setup your traffic speed is HALF of the Bandwidth of wireless protocal...

    I.E. if it's 54Mbs, the most you will get is 27Mbs. 27Mbs in both directions...

    One must factor in Distance, Signal Strength, Signal Quieting, the closer the better, use the very best gain antenna's/coax if you extending the antenna's, etc...

    27mbs times 2 = 54Mbs!!!



    I use the following setup the following for the Wireless Ethernet Bridge Mode [WEBM]
    I connect to the WRT54G-V2 on IP http://192.168.100.11/
    Using your Username & Password…

    Lets login… http://192.168.1.1/ for your router you are going to use for the [WEBM]!!!


    This was on IP 192.168.1.1 the default IP of Tomato Firmware. I changed it to.. 192.168.100.11
    It will come apparent why I used this IP see below...




    Click on the BASIC tab… Then Click on NETWORK page tab…

    WAN / Internet

    In the "Wireless" section, set "Wireless Mode" to "Wireless Ethernet Bridge."
    Notice that some sections of the configuration page disappear, including DHCP server settings.
    As with setting up wireless client mode, you next configure SSID, Channel, and Security to match the primary House Router & [AP]

    This will show up with stating… Wireless Ethernet Bridge Mode when we enable the wireless mode!!!


    LAN
    STATIC Router IP Address… 192.168.100.11
    Subnet Mask… 255.255.255.0
    Default Gateway… 192.168.100.1
    Static DNS #1… 192.168.100.1

    This is the DNS Relay Server of the House Router & [AP] which will relay DNS requests!!!
    This will also allow the TIME setting under the BASIC section to connect to the [NTP] Network Time Protocol servers and your logs will have the correct time displayed too!!!


    Static DNS #2… 0.0.0.0
    Static DNS #3… 0.0.0.0

    DHCP Server… NO


    Click "Save" at the bottom of the page to trigger the new settings. Tomato will restart.

    WIRELESS


    Enable it!!!
    Select... Wireless Mode Wireless Ethernet Bridge
    B/G Mode… MIXED
    SSID… ABC123XYZ… This is SSID of the House Router & [AP]

    Security… WEP
    Encryption… 128bits
    Passphrase…. Use the name you used on the House Router & [AP]…
    Put in the Generated keys… There should be [4] four of them!!! SELECT the Key you will be using, for this topic will use # 1

    Select the same Wireless Channel you are using on the House Router & [AP]

    Click "Save" at the bottom of the page to trigger the new settings. Tomato will restart.

    Click on the ADVANCED tab… Then Click on FIREWALL page tab…

    Allow Multicast… YES
    NAT Loopback… Allow Forward
    Anything else… NO

    The Firewall of the House Router & [AP] handles all the firewall settings for this network!!! So there's no need a Firewall here.

    Click "Save" at the bottom of the page to trigger the new settings. Tomato will restart.

    Okay… We are done... Now that wasn't so hard... ;^)

    Remember that in bridge mode, the House/Client Router & [AP] is "transparent," so any firewall or other network functions will be left up to the House Router & [AP].

    REMEMBER to... Click "Save" at the bottom of the page to trigger the new settings. Tomato will restart.

    This setup allows me to connect to everything behind my ISP Verizon FIOS service side of the network.

    I can login to 192.168.1.1 [ISP Router], 192.168.100.1 [House Router & AP], and every other device in my house, from any computer on my network.

    I keep my ISP Verizon FIOS service happy… they can connect and do there thing!!!
    I do not have their TV [DVR] service, but if I did this would not have any effect on them too!

    I can do whatever I want on my side of things using Tomato.

    I hope this helps in your understanding of routing using Tomato, etc…

    Cheers!!!
