    You're welcome. Let us know if it works out. Also to answer your other question:

    The omega will behave as a routed bridge in this case - meaning that it will assign addresses, maintain and manage the connection specifics of the devices connected to the switch (I am assuming you will be using a switch). So the ip addresses you see will be in the range from 192.168.3.2-200 or so. It will also be a private network of sorts (sorry I am not a networking expert to know the correct terminology) meaning that if you check on the main router you should be able to see only one IP address - that from the omega - your devices will be routed through the omega. I am not completely sure of the implications this will have on the speed of the connection but logically I assume it will be slower than connecting directly to the main router - unless you are not using any other device on the main router.

    This is a very rough explanation from my limited understanding of how these things work. I am sure there are other experts around these communities who can give you a much more detailed explanation.

    @Nayan got everything working with the exception of the wireless bridge can ping the Ethernet expansion IP address but still working on figuring out why devices on the switch connected to that port are not being seen. More reading and experimentation is at hand.

    @Guest ... Are you able to access the internet from the devices connected to the switch?

    @Nayan ran into some configuration problems, had to start over "factory reset". Will get back to the point I was and let you know.
    Not sure what affect attempting to create the wireless bridge( if possible) has on other wifi configurations within the omega still searching.

    @Lazar-Demin Just finished setting up the posting by @Haoran-Li
    "Using the Omega as a WiFi Ethernet Bridge" but could not get connectivity via the ethernet port on the omega.
    Wireless signal from Local router-->Omega receiving wireless signal --
    -->Ethernet connection on omega has laptop connected and setup for DHCP. No traffic. Here are the files I configured as per write up.

    @Lazar-Demin When finished with the "Using-Omega-As_WiFi-Ethernet-Bridge" will it function as shown? Failed on my first configuration attempt. Attempting a second setup but wanted to show what my configurations look like (show above this post) and convey my expectations. Sounds like it is getting closer.

    @Guest In the post with all of the configuration files, can you please edit the post to format the settings with code syntax? It's incredibly hard to read with the current formatting.
    There's a guide here: https://github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet#code

    I'll ask @Haoran-Li to take a look, meanwhile you should experiment as well, we definitely welcome innovation in the community

    @Nayan Still reviewing my files and attempting to get it working. In case there was a problem with the cables or laptop used a different set of components still fails. Can you see from the information posted if I have miss-configured anything called out in your tutorial? Have you successfully had this work on your end?
    Will go over the steps you call out again and see if there is something I am missing.

    @Nayan read your step by step instructions and took some notes following each step and checking it off but still could not get it to work could you review my steps and see where I am going wrong?

    Step 1: Connect Omega with WiFi
    Pretty straight forward using the gui for this setup portion.
    Step 2: Enable the Ethernet Connection in Omega
    Basically what we need to do is to uncomment the following part licated at /etc/config/network:

    config interface 'lan'
	option ifname 'eth0'
	option type 'bridge'
	option proto 'static'
	option ipaddr '192.168.3.1'
	option netmask '255.255.255.0'
	option ip6assign '60'

    Step 3: Connect the Two Interfaces via Firewall Configuration
    There is another tutorial (as I said), click here.
    This tutorial is how to make Omega as a router.
    The theory is the same, all we need to do is to convert
    what is going on in the tutorial.
    Step 3a: Turning the Omega Into a WiFi Router
    Open up the /etc/config/network file, and add the following line at the end of the file:

    config interface 'wan' 
	option ifname 'eth0' 
	option proto 'dhcp'   
	option hostname 'OnionOmega'

    Then restart netowrk /etc/init.d/network restart
    Step 3b: Step 4: Configuring the WiFi Settings
    Next, you will need to open up the /etc/config/wireless file and configure two things.
    First, you should disable the WiFi network that the Omega is currently connected to.
    You can do this by deleting or commenting out a block that looks something like the following:

     config wifi-iface
	option device 'radio0'
	option mode 'sta'
	option network 'wwan'
	option ssid 'WiFi Network'
	option encryption 'psk2'
	option key 'TopSecret'
	option disabled '0'

    Next, you might want to configure the WiFi network that the Omega will be serving.
    You can do this by editing the following block:
    Within this block, you can change the SSID of your Omega,
    as well as the type of encryption you want to use for the router.
    NOTE CHECK ON ENCRYPTION USED ON LAN COMPARE TO ENCRPTION SET ON OMEGA

        config wifi-iface
	option device 'radio0'
	option network 'wlan'
	option mode 'ap'
	option encryption 'psk2'
	option ssid 'OmegaRouter'
	option key 'RouterPassword'

    Once you have finished customizing the WiFi network, simply save and close the file,
    and run the following command to restart the WiFi network:
    wifi
    Step 3C: Enabling Packet Routing

    Next, you will need to open up the /etc/config/wireless file and configure two things.
    First, you should disable the WiFi network that the Omega is currently connected to.
    You can do this by deleting or commenting out a block that looks something like the following:

    config wifi-iface
	option device 'radio0'
	option mode 'sta'
	option network 'wwan'
	option ssid 'WiFi Network'
	option encryption 'psk2'
	option key 'TopSecret'
	option disabled '0

    'Next, you might want to configure the WiFi network that the Omega will be serving.
    You can do this by editing the following block:
    Within this block, you can change the SSID of your Omega,
    as well as the type of encryption you want to use for the router.
    NOTE CHECK ON ENCRYPTION USED ON LAN COMPARE TO ENCRYPTION SET ON OMEGA <---my comment

    config wifi-iface
	option device 'radio0'
	option network 'wlan'
	option mode 'ap'
	option encryption 'psk2'
	option ssid 'OmegaRouter'
	option key 'RouterPassword'

    Once you have finished customizing the WiFi network, simply save and close the file,
    and run the following command to restart the WiFi network:

    wifi

    Step 3C: Enabling Packet Routing
    Next, you will need to configure the Omega to route packets from the ethernet interface
    (eth0) to your WiFi interface (wlan0). To do this, you will be editing the /etc/config/firewall file:
    find the the block that looks something like the following:

    config zone
	option name     		wan
	list   network      'wwan'
	#list   network     'wan6'
	option input        ACCEPT
	option output       ACCEPT
	option forward      ACCEPT
	option masq     1
	option mtu_fix      1

    and add the following line:

    list   network      'wan'

    What you will end up with is something like the following:

    config zone
	option name     		wan
	list   network      	'wwan'
	list   network      	'wan'
	#list  network     		'wan6'
	option input        	ACCEPT
	option output       	ACCEPT
	option forward      	ACCEPT
	option masq     		1
	option mtu_fix      	1

    What this tells the Omega to do is to add the wan network
    (which we defined in /etc/config/network file)
    to a firewall zone called wan.
    This zone has already been setup to route packets to another firewall zone
    called lan, which contains the wlan0 interface.

    Once you have saved and closed the file, run the following command to restart the firewall with the
    updated configuration:

    /etc/init.d/firewall restart

    Once we understand what is going on, we can modify the file. What we are actually doing is to add a single line
    of configuration under zone lan.

    list   network      `lan`

    list means access list, you can get the information through Openwrt Firewall configuration page.

    Now, the configuration looks like this:

    config zone
	option name     lan
	list   network      'wlan'
	list   network      'lan'
	option input        ACCEPT
	option output       ACCEPT
	option forward      ACCEPT

    Now we need to restart the service, by doing /etc/init.d/firewall restart and /etc/init.d/network restart
    (firewall goes first), or simply reboot Omega.
    Step 4: Connect to Lan Switch via Ethernet
    Since we configured all the things, and restarted the service, now we should be able to connect with other
    devices via ethernet. Unfortunately, Onion does not provide an tutorial about how to connect my laptop to Omega.

    Make sure that your connection is set to Obtain IP address and DNS address Automatically. It should be set so by default.

    Using this Setup
    If you have a device that only can be connected via Ethernet and you only have WiFi available, you could apply this tutorial to make it work!

    @Guest erm... is this just the tutorial from https://wiki.onion.io/Tutorials/Using-Omega-As-Wifi-Ethernet-Bridge pasted into the forum???

    It is actually the combination of two tutorials showing the steps taken to achieve the end result. Posted in an effort to share with @Nayan my exact steps taken as well as using it during my setup as a check off sheet. When carrying out the tutorial it was helpful to see the actual steps rather then links to other steps. As of now have not successfully completed this setup configuration and @Nayan might find it useful to trace my steps and see why it has failed.
