Before we can proceed with this guide, you will need to know what your ExtremeVPN credentials are, as they are essential during manual configuration. If you don’t know it, you can follow these steps to access them;

• Visit the ExtremeVPN member area. You can click here to visit our member area.
• Enter your ExtremeVPN registered email address and password in the space provided and click on Login.
• Once logged in, click on the Subscription tab, which you will see on the left panel.
  On the subscription page, scroll down to see your VPN credentials.
• You can see and copy your ExtremeVPN credentials, username, and password. Click on the Eye icon beside your password to make it visible and easier to copy.

Here is an advanced guide on how you can connect your router using the OpenWRT firmware version 21.02 to ExtremeVPN;

• The first step is to get a router flashed with the OpenWRT firmware version 21.02 and an enabled ExtremeVPN client.
• You will need to enable an SSH connection on your router. You must download one from a third-party SSH client like PuTTY to enable SSH access.
• The ExtremeVPN package will not be included in the firmware image, so you must install it.
• Install Putty and access your router IP. You can type your router IP address in the space provided under Host Name (or IP address). In this case, we use 192.168.1.1, the default IP address for the Linksey e900 router. Click on Open after typing the IP address.
• On the next window, enter the Root and Password of your Router.
• You will need to run the following commands to install ExtremeVPN:

1. opkg update
2. opkg install luci-app-extremevpn
3. opkg install extremevpn-openssl opkg install ip-full

• Next, you must download the ExtremeVPN configuration files, which you can find here.
• After downloading the zip file, unzip the files to a known location and go to either the TCP or UDP folder containing the ExtremeVPN files. For example, we will use a Spanish server with the file es2-evpn.evpn.
• You also need to copy specific files from your computer to your router. You must activate SFTP (SSH File Transfer Protocol) on the router to do that. You can do that by running the following SSH commands;

1. opkg update
2. opkg install openssh-sftp-server
3. You can now copy the desired file ‘es2-evpn.evpn’ to the /etc/extremevpn/folder of the router using the WinSCP on Windows.

• Right-click on the router side and select a new file with the name secret (it does not have a file extension). Enter your ExtremeVPN credentials in the next window.
  Save and close the file.
• Edit the es2-evpn.evpn and save the path in the secret file that contains your VPN credentials.
• Save and close the file once you are done.
• To configure ExtremeVPN (while also using the SSH connection provided by PuTTY), identify the file name in /etc/config/extremevpn. Run the following commands:

1. uci set extremevpn.extremevpn=extremevpn
2. uci set extremevpn.extremevpn.enabed=’1’
3. uci set extremevpn.extremevpn.config=’/etc/extremevpn/es2-evpn.evpn’
4. uci commit extremevpn

Note that es2-evpn.evpn is the ExtremeVPN file used for this guide. When following this guide, you must enter your preferred file’s complete name in the place where es2-evpn.evpn is written.

• Create a new network interface by following these commands;
• uci set network.extremevpntun=interface
• uci set network.extremevpntun.proto=’none’
• uci set network.extremevpntun.ifname=’tun0’
• uci commit network
• You can now make a new firewall zone and configure a forwarding rule to allow traffic from the LAN to the VPN. Use the following commands;

1. uci add firewall zone
2. uci set firewall.@zone[-1].name=’vpnfirewall‘
3. uci set firewall.@zone[-1].input=’REJECT’
4. uci set firewall.@zone[-1].output=’ACCEPT‘
5. uci set firewall.@zone[-1].forward=’REJECT‘
6. uci set firewall.@zone[-1].masq=’1′
7. uci set firewall.@zone[-1].mtu_fix=’1′
8. uci add list firewall.@zone[-1].network=’extremevpntun‘
9. uci add firewall forwarding
10. uci set firewall.@forwarding[-1].src=’lan’
11. uci set firewall.@forwarding[-1].dest=’vpnfirewall‘
12. uci commit firewall

• Next, you will need to set up DNS on your router. You can use DNS from Google for the WAN interface of your router. Follow these commands to set up the router DNS;

1. uci set network.wan.peerdns=’0′
2. uci del network.wan.dns
3. uci add_list network.wan.dns=’8.8.8.8′
4. uci add_list network.wan.dns=’8.8.4.4′
5. uci commit
6. Reboot your router

• Ensure you wait 1-2 minutes after rebooting the router before logging in again. Once you re-login, go to the ExtremeVPN tab, which you will find under VPN, and check your connection status.
• You have successfully activated your ExtremeVPN profile and connected your router to the VPN.

Here are the steps to configure ExtremeVPN on the OpenWRT 18.06 router version;

• Using PuTTY or any SSH client of your choice, log in as Root to the router.
• Your default IP address is 192.168.1.1, but yours might be different. If you do not know your router’s IP address, check with your router’s customer support.
• Enter your username and password. The router’s default username and password are boot set as root, but this might be different if you have changed yours from the default.
• Ensure that your VPN package is updated to the latest on your device. Run the command below to do so;

1. opkg update

• Install the ExtremeVPN client package: opkg install extremevpn-opensslluci-app-extremevpn
• Next, go to /etc/extremevpn/ and create a file called vi tls-auth.key.
• From the ExtremeVPN package folder you just downloaded, open the Wdc.key file. Copy and paste the file’s contents to a text editor and save it there.
• The next step is to create a file called userpass.txt. Type it as vi userpass.txt.
• You can now enter your ExtremeVPN credentials.

You will need to create the ExtremeVPN configuration. To do this;

• Login to your router’s Luci web panel from your default browser.
