===IPv6 to IPv4 tunnel setup===
This article contains step-by-step instructions on how to set up bidirectional communication between two serial RS232 devices over TCP/IP.
Setup IPv6 over IPv4, also known as 6in4 IPv6 transition mechanism
----


To create a new tunnel, click on '''create regular tunnel''' ('''1'''), then '''enter''' your '''public IP''' (it will light up green, if the tunnel can be created with this IP) ('''2'''), '''select''' the desired '''tunnel server''' ('''3''') and '''create tunnel''' ('''4''').
==Configuration overview & prerequisites==


[[File:Create IPv6 Tunnel.png|border|center|class=tlt-border|854x854px]]
End devices are connected to separate RUT956 routers through RS232 connection, and client connects to the server through its Public IP address.


After successful tunnel creation, you will be prompt to tunnel details window.

'''Prerequisites''':


To create a a tunnel instance on your RUT router, '''navigate''' to '''example configurations''' ('''1''') and select '''OpenWRT Barrier Breaker''' ('''2'''). Copy and paste the following commands into your RUT CLI. Do not forget to '''replace''' '''YOUR_TUNNELBORKER_USERNAME''' and '''YOUR_TUNNELBROKER_PASSWORD''' with your '''TunnelBroker account username''' and '''password'''.
*Two devices with RS232 support
*Two end devices (PCs or RS232 devices able to send and receive data, here we will be using PCs with serial simulators)
*Over IP Server must have a SIM card with a Public Static or Public Dynamic IP address (more on IP address types here) to make remote access possible

A new tunnel interface has been successfully created.
====Obtaining Public IP: Set an APN====
 
[[File:Tunnel RUT interface created.png|border|center|class=tlt-border|554x554px]]
 
==Relayd configuration==
Relay is a daemon (computer program that runs as a background process) used to relay and dynamically redirect incoming connections to a target host. Its main purpose in RUTxxx routers is to extend the wireless network. For example, when RUTxxx is in STA Wireless Station mode, it can be used to bridge WAN and LAN interfaces to create a larger Wireless network.
 
This article provides an extensive configuration example of a basic Relay usage scenario with two RUTxxx devices.
===Relayd installation===
----
----
Install relayd package if needed, skip this step on RUTX series devices or if you already installed it on your router
In this example we are using Public IPs, it also works with Private IPs if routers are in same LAN
<pre>opkg update
opkg install relayd</pre>


===WiFi client configuration===
'''Note:''' If you have a Public IP address already, you can skip this step.
----
Add WiFi interface to make your router act as a WiFi client (connect to another AP)


<pre>uci add wireless wifi-iface
To set the APN, while in the router's WebUI, navigate to the '''Network → Mobile → General → Interface mob1s1a1 APN configuration''':
uci set wireless.@wifi-iface[-1]=wifi-iface</pre>


Add new WiFi interface to 2.4ghz device, can specify 'radio1' for 5ghz
[[File:Set APN PF.png|border|class=tlt-border|alt=]]


<pre>uci set wireless.@wifi-iface[-1].device='radio0'
Once in the '''Interface mob1s1a1 APN configuration''' window, edit your mobile interface, find the '''APN''' field and enter you Internet Service Provider's APN:
uci set wireless.@wifi-iface[-1].mode='sta'
# '''Disable the Auto APN option'''
uci set wireless.@wifi-iface[-1].network='wifi_wan'</pre>
# Choose the correct '''APN''', which gives out a public IP address (for more information about that contact your Internet Service Provider)


Change SSID here to an SSID that the router will be connecting to
[[File:Set APN PF APN selected.png|border|class=tlt-border]]


<pre>uci set wireless.@wifi-iface[-1].ssid='RUT_4474_2G'</pre>
Additional notes on APN:
* '''NOTE 1''': don't use the exact APN value as seen in the example above as it will not work with your SIM card. APN depends on your Internet Service Provider (ISP), therefore, your ISP should provide you with their APN or, in many case, you can find your ISP's APN with an online search.
* '''NOTE 2''': furthermore, it should be noted that not all SIM cards support this functionality. Static or Dynamic Public IP addresses (obtained through APN) are a paid service and setting any APN value for a SIM card that doesn't support this service will most likely result in losing your data connection. If this is the case, it can be fixed by simply deleting the APN, but it also means that remote access through mobile WAN IP will most likely not work on your SIM card.
* '''NOTE 3''': in some cases the SIM card doesn't require an APN in order to obtain a Public IP address. If that is the case for you, simply check what your router's mobile WAN IP address is - if it's already a Public IP address, then you don't need to set an APN. The easiest way to find what your mobile WAN IP address is to log in to the router's WebUI and check the '''MOB1S1A1''' widget in the '''Overview''' page:


Change BSSID here to BSSID that the router will be connecting to (L2 address)
[[File:Where public IP.png|border|class=tlt-border]]


<pre>uci set wireless.@wifi-iface[-1].bssid='00:1E:42:44:44:74'</pre>


Use appropriate auth method, PSK2 = WPA2-PSK here
===Over IP Server RS232 configuration===
----
Navigate to the Over IP tab by going to '''Services → Serial Utilities → Over IP''' . Insert desired name and select RS232. Make sure to '''enable the instance''' '''(1)''' and '''configure Serial port in accordance''' '''(2)''' to connected device, these should match on both routers to avoid miscommunication.

Introduction

This article contains step-by-step instructions on how to set up bidirectional communication between two serial RS232 devices over TCP/IP.

Configuration overview & prerequisites

End devices are connected to separate RUT956 routers through RS232 connection, and client connects to the server through its Public IP address.

Prerequisites:

  • Two devices with RS232 support
  • Two end devices (PCs or RS232 devices able to send and receive data, here we will be using PCs with serial simulators)
  • Over IP Server must have a SIM card with a Public Static or Public Dynamic IP address (more on IP address types here) to make remote access possible

If you're having trouble finding this page or some of the parameters described here on your device's WebUI, you should turn on "Advanced WebUI" mode. You can do that by clicking the "Advanced" button, located at the top of the WebUI.

Over IP Server

Obtaining Public IP: Set an APN

In this example we are using Public IPs, it also works with Private IPs if routers are in same LAN

Note: If you have a Public IP address already, you can skip this step.

To set the APN, while in the router's WebUI, navigate to the Network → Mobile → General → Interface mob1s1a1 APN configuration:

Once in the Interface mob1s1a1 APN configuration window, edit your mobile interface, find the APN field and enter you Internet Service Provider's APN:

  1. Disable the Auto APN option
  2. Choose the correct APN, which gives out a public IP address (for more information about that contact your Internet Service Provider)

Additional notes on APN:

  • NOTE 1: don't use the exact APN value as seen in the example above as it will not work with your SIM card. APN depends on your Internet Service Provider (ISP), therefore, your ISP should provide you with their APN or, in many case, you can find your ISP's APN with an online search.
  • NOTE 2: furthermore, it should be noted that not all SIM cards support this functionality. Static or Dynamic Public IP addresses (obtained through APN) are a paid service and setting any APN value for a SIM card that doesn't support this service will most likely result in losing your data connection. If this is the case, it can be fixed by simply deleting the APN, but it also means that remote access through mobile WAN IP will most likely not work on your SIM card.
  • NOTE 3: in some cases the SIM card doesn't require an APN in order to obtain a Public IP address. If that is the case for you, simply check what your router's mobile WAN IP address is - if it's already a Public IP address, then you don't need to set an APN. The easiest way to find what your mobile WAN IP address is to log in to the router's WebUI and check the MOB1S1A1 widget in the Overview page:


Over IP Server RS232 configuration

Navigate to the Over IP tab by going to Services → Serial Utilities → Over IP . Insert desired name and select RS232. Make sure to enable the instance (1) and configure Serial port in accordance (2) to connected device, these should match on both routers to avoid miscommunication.


Over IP Server configuration

After applying RS232 configuration scroll down and configure Over IP Server:

  1. Mode Server- the device waits for incoming connections.
  2. Select a desired protocol, TCP or UDP.
  3. TCP/UDP port - specify desired port.


IP Filter

Once finished the above configuration, add interfaces through which routers will be communicating, You can add IP address that will be allowed to connect or enter 0.0.0.0 to allow all connections coming through correct port.


OverIP Client

OverIP Server RS232 configuration

Navigate to the OverIP tab by going to Services → Serial Utilities → OverIP . Insert desired name and select RS232. Make sure to enable the instance (1) and configure Serial port in accordance (2) to connected device, these should match on both routers to avoid miscommunication.


OverIP Client configuration

After applying RS232 configuration scroll down and configure Over IP Server:

  1. Mode Client – the device initiates the connection.
  2. Select a desired protocol, TCP or UDP.
  3. Address is the Over IP Sever Public IP address. Port is the port we have configured on the Over IP Server device.

Testing configuration

If you followed configuration steps both end devices should be able to send and receive data. In this example we use Hercules program on both computers and open serial communication with routers. We are able to send and receive data through RS232.
