+This guide was developed using a `Nokia G-240W-B` router (software version 3FE47969AGCA21). It should work for other models in the `G` series.
+
+!!! note
+There is no single way to do it right. Choose the one best suited for you.
+This guide is `IPv4` and `IPv6` compatible, but it is not mandatory to use `IPv6`.
+
+### Prerequisites
+
+- The `Raspberry Pi` is using static IP address, `IPv4` and `IPv6` as well. This can be a fixed DHCP assignment or configured statically on the Pi itself.
+- The `ISP` provides `IPv6` address, prefix and gateway to the router.
+
+### Grab your IPv4 and IPv6 address from your Raspberry Pi
+
+SSH into your `Raspberry Pi`. A quick `ifconfig eth0` (substituting `eth0` for the applicable network interface) will get you the address information:
+
+```bash
+eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
+        inet 192.168.1.10  netmask 255.255.255.0  broadcast 192.168.1.255
+        inet6 2806:103e:1f:2ace:22a1:de1d:e1bf:30dc  prefixlen 64  scopeid 0x0<global>
+        inet6 2806:103e:1f:2ace:7d21:7337:7817:2fb2  prefixlen 128  scopeid 0x0<global>
+        inet6 fe80::e6f3:5490:577e:4fed  prefixlen 64  scopeid 0x20<link>
+        inet6 fe80::192:168:1:10  prefixlen 64  scopeid 0x20<link>
+        ether e4:5f:01:cd:8e:e1  txqueuelen 1000  (Ethernet)
+        RX packets 4342  bytes 704995 (688.4 KiB)
+        RX errors 0  dropped 0  overruns 0  frame 0
+        TX packets 3376  bytes 661707 (646.1 KiB)
+        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
+```
+
+The relevant lines here are `inet 192.168.1.10  netmask 255.255.255.0` and `inet6 fe80::192:168:1:10 prefixlen 64`
+
+Worth to mention that the `IPv6` address that starts with `fe80` is the `link-local` address and it is used in this guide, the other addresses that start with `2806` are the global addresses and they are assigned by the router.
+
+### IPv4 configuration
+
+Go to **Network** --> **LAN**
+
+1. Set `IPv4 address` to the default gateway address, `192.168.1.1` or `192.168.1.254` depending on your specific router configuration.
+2. Set `Subnet mask` to `255.255.255.0`
+3. Set `Primary DNS` to `192.168.1.10` (the `IPv4 eth0` address)
+4. Set `DHCP Enabled` (update IP address range if needed)
+5. Click `Save`
+
+All client devices connected to the network should now automatically be configured with a single `192.168.1.x` address for the `DNS` resolution.

+
+### IPv6 configuration
+
+Go to **Status** --> **WAN Status IPv6**
+
+Take note of the following `Link Local IPv6 address` (e.g. `fe80::1`)
+In this case the prefix is used to create the static addresses for the `eth0` interface. Other dispositives will use the same prefix to create their addresses automatically.
+
+![Screenshot of LAN IPV6](../images/routers/nokia-g240wb-prefix-ipv6.png)
+
+Go to **Network** --> **LAN_IPv6**
+
+**IPv6 LAN Host Configuration**
+
+1. Set `DNS Server` to `static`
+2. Set `Preferred DNS` to `fe80::192:168:1:10` (the `IPv6 eth0` address)
+3. Set `LAN Prefix` to `1_LAN_Prefix` (the `ISP` provided prefix)
+4. Set `Enable` checkbox
+5. Click `Save/Apply`
+
+![Screenshot of LAN IPV6 1](../images/routers/nokia-g240wb-lan-ipv6-1.png)
+
+**DHCPv6 Server**
+
+1. Set `Enable` checkbox (this means using ULA addresses)
+2. Click `Save/Apply`
+
+**DHCPv6 Server Pool**
+
+1. Set `LAN Prefix` to `1_LAN_Prefix`
+2. Click `Save/Apply`
+
+![Screenshot of LAN IPV6 1](../images/routers/nokia-g240wb-lan-ipv6-2.png)
+
+**RouterAdvertisement**
+
+1. Set `Enable` checkbox
+2. Set `LAN Prefix` to `1_LAN_Prefix` (the `ISP` provided prefix)
+3. Set `Whether the address info through DHCP` checkbox
+4. Set `Whether other info obtained through DHCP` checkbox
+5. Click `Save/Apply`
+
+All client devices connected to the network should now automatically be configured with `fe80::xxxx:xxxx:xxxx:xxxx` router address.
