What is Network Mobility (NEMO)?

NOTE: NEMO requires a feature license. Go to System Settings → Feature Licenses to enable this feature.

Network Mobility (NEMO) is an Internet standards track protocol defined in RFC 5177. The protocol allows session continuity for every node in a mobile network as the network moves.

NEMO requires a service provider, e.g. Verizon Wireless Private Network with DMNR (Dynamic Mobile Network Routing). Your NEMO service provider will define many of the settings for your NEMO configuration.

Once you have a NEMO service provider and a valid feature license, add networks to the Networks Routed by NEMO section by first clicking Add. In the popup window, input:

  • Network Address
  • Netmask

The Network Address and Netmask, or subnet mask, together define a range of IP addresses that comprise the local network you want associated with the NEMO settings.

Network Mobility (NEMO) Settings

Home IP Address and Home Netmask – These may be provided by your NEMO service provider. The IP address is a placeholder, “dummy” address; any IP address can be used (1.2.3.4 is common).

Home Agent IP AddressHome Agent Password, and Home Agent SPI – Your home agent will be defined by your NEMO service provider.

Renew Registration – The NEMO network regularly re-registers with the home agent (e.g., every 30 seconds). Specify the number of seconds between each check-in.

MTU – Override the maximum transmission unit (MTU) of the NEMO tunnel. The TCP MSS (maximum segment size) is automatically derived from the MTU. Leave blank to rely on Path MTU Discovery.
