Information Requirements

Static Internet connection information for remote customer site (where Transfer point is to be installed)

IP Address in slash notation EX: 216.133.162.67/28 = IP Address 216.133.162.67 NetMask 255.255.255.240

Default Gateway for connection EX: 216.133.162.65

Network Address EX: 216.133.162.64

IP address block explained. the /28 limits the Block of addresses to 16 as follows:

216.133.162.64 - Network Address (1 address)

216.133.162.65 - Gateway Address (1 address)

216.133.162.66 - 216.133.162.79 14 useable addresses)

Initial Configuration Setup

<br\><br\>

Set up RB751U-2HnD Router for initial configuration

Document the MAC addresses range from the bottom of the unit. IE 00:0C:42:AE:F2:7C - 00:0C:42:AE:F2:81 (5 addresses). These will be used to connect to the device and be logged in AdminCenter.

Connect to power

Connect cat 5 cable from Port ETH5 to the NIC for Idrive wireless

Change settings for wireless NIC on your computer to:

-192.168.88.10

-255.255.255.0

<br\><br\>

Connect using Winbox

Download and install Winbox Configuration tool for RouterOS.

Run Winbox.exe or double click the icon on the desktop

Enter the Default "Connect To" IP Address: 192.168.88.1

Login: admin

password: blank

Click "Connect"

Upon initial log in the "RouterOS Default Configuration" pop-up window will appear. Choose "OK". We are not concerned about the default settings because they will be overwritten with the idrive default configuration file.

Create a backup of the default configuration just in case

Files >Backup

<br\><br\><br\><br\>

Upgrade OS and Firmware

Obtain the latest versions (V6.x) from the MicroTik [|download] site

Click on the correct link for the hardware architecture (mipsbe for RB751U-2HnD)

Click on "All Packages" and click Save

Extract all of the files from zip package

Copy the files from your computer to the Router Board by dragging and dropping all of the files into the files list in the WinBox window

Restart the router and log back into the router and confirm that WinBox shows the new version of RouterOS and Firmware

<br\><br\>

Setup using Restore configuration file (Recommended)

Load Idrive Standard configuration

For simplicity and consistency it is better to set the routers configuration using the RouterOS backup/restore function. This "restores" the standard idrive configuration from a .backup file. This will leave only a few custom settings that are specific to the customer location(s).

Download the most current .backup file from Admin Center

Unzip the file to the Desktop on your computer

In WinBox select “Files” from the left menu to open the Files List window.

Use the mouse to drag and drop the configuration file from the Desktop into the Files List (uploads the file to the Router)

Highlight the config file and click on "Restore"

The router will reboot with the new configuration. You will need to use the new IP address and password

-The new IP address for Ports 3 - 5 will be 192.168.0.3

-Change the IP address on your NIC to 192.168.0.10

Reconnect to the Router with the "Connect to" address of 192.168.0.3, password idrive#

<br\><br\><br\><br\><br\><br\>

Set Customer/Location Specific Settings

Static Internet IP Address

Click IP >Address to open the Address list form. Double Click on address to edit. All three interface addresses are shown open here. You should only need to change the ether1 address.

Modify the internet connection address for the customer's location.

ether1 - This must be configured prior to shipment or you will not be able to contact the Transfer Point when it is installed at the customer location!!!.

Enter Static IP address (216.133.162.67/28 in this example)

Enter Network Address (216.133.162.64 in this example)

Interface "ether1"

bridge_local - No need to change unless there is more than one Remote Transfer point in the Idrive system. This is the IP address that the base station will see. Ports 3,4,5 share this address.

IP Address 192.168.0.3/16

Network 192.168.0.0

Interface bridge_local

ether2 - Set by config file and does not need to be changed.

IP Address 1.1.1.2/24

Network 1.1.1.0

Interface ether2

<br\><br\>

Set SSTP Dial Out address

Set the Dial Out address (Static IP address of the base stations internet connection)This is the number that the Transfer Point "calls" to contact the base station.

<br\><br\>

Set Timezone for customer location

Set the timezone. The Date and time will be set by NTP (Network Time Protocol) when connected to the internet

<br\><br\>

Network Cable Connections

EHT1 - Internet

ETH2 - loopback cable to ETH3

ETH3 - loopback cable to ETH2

ETH4 - Optional extra AP (192.168.0.3)

ETH5 - Optional extra AP (192.168.0.3)

<br\><br\>

Routes configuration

Add the three routes

route <0.0.0.0/0> - set the Gateway address for the customers internet gateway at the remote location. Leave Dst. Address all zeros.

route <192.168.0.0/16> - routes 192.168.x.x (events) traffic through the tunnel to the base station.

route <216.133.162.64/28> - Routes all internet traffic out the Ether1 interface. The address is the Network address for the remote location internet connection.

<br\><br\>

NTP configuration

Network Time Protocol - keeps the time syncronized

<br\><br\>

3G notes from Florin

Connect your 3G USB dongle and restart router.

Return on "Interface List" and double-click "ppp-out1" and make sure that "usb1" option is selected. If the "Port" drop-down list is empty then your 3G dongle is not supported.

Our 3G USB worked by default without any other configuration. Click on "Advanced Mode" if your SIM does require mobile carrier configuration.

Functional testing troubleshooting

Initial Installation Checks

<br\><br\>

Internet connection working ?

Connect using Winbox

Connect using a browser

Telnet into the Terminal Point using Putty

Ping the terminal point

<br\><br\>

connected to base station?

Ping the base station public IP address

Check the structure using neighbor discovery (192.168.0.2 is at the base station end). This shows connectivity as well as the tunnel working.

<br\><br\>

View other Wifi in the area

View the amount of traffic on each channel

<br\><br\>

extra APs connected and functioning?

Ping the additional AP(s)
