How to set up IPV6 tunnel on 3G/4G Wireless Router TL-MR3420 (new logo)

The IPv6 Tunnel feature helps you obtain IPv6 resources based on an IPv4 WAN connection or vice versa.

IPv6 Tunnel is a transition mechanism that allows isolated IPv6 hosts and networks to reach each other over IPv4-only infrastructure before IPv6 completely supplants IPv4. It is a temporary solution for networks that do not support native dual-stack, where both IPv6 and IPv4 run independently.

The router provides three tunneling mechanisms: 6to4, 6rd and DS-Lite. The way to set up 6rd and DS-Lite tunnel are similar.

Note: TL-MR3420_V5 is used for demonstration in this article.

Use the Public IPv6 Tunnel Service-6to4

The 6to4 tunnel is a kind of public service. If there are any 6to4 servers on your network, you can use this mechanism to access IPv6 service. If your ISP provides you with an IPv4-only connection but you want to visit IPv6 websites, you can try to set up a 6to4 tunnel.

I want to: Set up the IPv6 tunnel though my ISP doesn’t provide me with the tunnel service.

How can I do that?

1. Visit http://tplinkwifi.net, and log in with the password you set for the router. For details, please refer to How do I log into the web-based Utility (Management Page) of TP-Link wireless router?

2. Go to Advanced > Network > IPv6 Tunnel.

3. Tick the check box, select 6to4 as the tunneling mechanism and select a WAN connection from the drop-down list, then click Save.

Note: If there is no available WAN connection to choose, make sure you have connected to the internet.

Now you can visit the IPv6 websites with the 6to4 tunnel.

Note: Still not being able to access IPv6 resources means that not any 6to4 public server was found in your network. You can contact your ISP to sign up for IPv6 connection service.

Specify the 6rd Tunnel with Parameters Provided by Your ISP

I want to: Specify the 6rd tunnel with the parameters provided by my 6rd tunnel service provider.

How can I do that?

1. Visit http://tplinkwifi.net, and log in with the password you set for the router. For details, please refer to How do I log into the web-based Utility (Management Page) of TP-Link wireless router?

2. Go to Advanced > Network > IPv6 Tunnel.

3. Tick the check box, select 6rd as the tunneling mechanism and select a WAN connection from the drop-down list.

4. According to the parameters provided by your ISP, choose Auto or Manual. More parameters are needed if you choose Manual.

5. Click Save.

Note: If there is no available WAN connection to choose, make sure you have connected to the internet and the connection type is not Bridge.

Now you can visit the IPv6 websites with the 6rd tunnel.

Tips: The way to set up DS-Lite tunnel is similar to that of 6rd tunnel. If you are provided with an IPv6-only WAN connection and have signed up for DS-Lite tunnel service, specify the DS-Lite tunnel by referring to the steps above.
