The Routes page displays the device’s Address Resolution Protocol (ARP) table and active IPv4 and IPv6 routes.
The information on this page has been updated in accordance with the RUT2XX_R_00.01.12.x firmware version.
The Address Resolution Protocol (ARP) is a communication protocol used for mapping an Internet Protocol (IP)address to a device’s Media Access Control (MAC) on the local network.
The ARP section displays the device’s ARP cache (also known as ARP table) data. The ARP cache contains information on each known MAC address and its corresponding IP address. When the device receives a packet destined for a local host, the ARP program attempts to find a physical host or MAC address in the ARP cache that matches the IP address. If the ARP cache doesn’t contain the needed IP address, ARP broadcasts a request packet to all LAN machines in order to find the device with the IP address in question.
The image below is an example of the ARP section on the Routes page.
You can also view the ARP cache via shell using the arp or ip neigh commands, depending on which output your prefer.
root@Teltonika-RUT240:~# arp IP address HW type Flags HW address Mask Device 192.168.1.103 0x1 0x2 ac:e2:d3:00:00:00 * br-lan 192.168.1.151 0x1 0x2 18:d6:c7:00:00:00 * br-lan

The Active IP Routes section displays the device’s routing table. A routing table contains a list of routes to network destinations associated with and known by the device.
The image below is an example of the Active IP Routes section on the Routes page.
You can also view the routing table via shell using the route or ip route commands, depending on which output your prefer:

The Active IPv6-Routes section displays the device’s IPv6 routing table. The image below is an example of the Active IPv6-Routes section of the Routes page.
You can also view the routing table via shell using the route -A inet6 or ip -6 route show commands, depending on which output your prefer.
root@Teltonika-RUT240:~# ip -6 route fe80::/64 dev wwan0 proto kernel metric 256
