| + | ==Testing DHCP over L2TPv3== |
| + | To test the realy settings go to DHCP server to check that devices are able to recieve IP addresses in the range 192.168.10.150 - 192.168.10.170 either via LAN port or Wi-Fi. Access the CLI and run '''cat /tmp/dhcp.leases''' to list all DHCP clients. |

| + | |
| + | Asking for the Address Resolution Protocol (ARP) table is also an other method to find hosts on the LAN network. |
