• Netmask – This is the corresponding subnet mask of the network being defined (Default: 255.255.255.0).
You can set the tunnel to connect to a range of IP addresses or to a single IP address. For example, you could
input 192.168.0.0 and 255.255.255.0 to connect your tunnel to all the addresses of the remote network in
the 192.168.0.x range. Alternatively, you could select a single address by inputting that address along with a
Netmask of 255.255.255.255.
Add/Edit Tunnel – Keep Alive
GRE keep-alive packets can be enabled to be sent
through the tunnel in order to monitor the status of the
tunnel and more accurately determine if the tunnel is
alive or not.
GRE keep-alive packets may be sent from both sides of a
tunnel, or from just one side.
Enabled: Select to enable GRE Keep Alive to continually
send keep-alive packets to the remote peer.
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.
NEMO
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.
NOTE: NEMO requires a feature license not included with ECM Prime. Go to SYSTEM > Administration > Feature
Licenses to enable this feature.
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 - This is the network address that is the destination of the route. This should be set to
the network address at the remote side of the tunnel.
• Netmask - This is the corresponding subnet mask of the network being defined (Default: 255.255.255.0).
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.
