Rate: Choose the length of time in seconds for each check (Default: 10 seconds. Range: 2 – 3600 seconds).
Retry: Select the number of attempts before the GRE tunnel is considered down or up (Default: 3. Range: 1 – 255).
Failover
Tunnel and Failback
Tunnel: Use these settings to create two tunnels – one as the primary tunnel and one as the backup tunnel. To
configure tunnel failover/failback, complete the following steps:
1. Create two tunnels: one for primary and one for backup. Make sure both tunnels have Keep
Alive enabled.
2. Choose one to be the primary tunnel. Open the editor for this tunnel and make sure Tunnel
Enabled is selected. Then go to the Keep
Alive
page. Under Failover
Tunnel select the other tunnel you have created.
3. Open the editor for the failover tunnel. Make sure Tunnel
Enabled is not selected. On the Keep
Alive page, set the Failback
Tunnel to your
primary tunnel.

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.
