The Security Gateway emulator is used in the CDMA2000 Simple IP VPN, GGSN Nodal, and LNS Node test cases to simulate an L2TP VPN gateway on the perimeter of a private network. It is defined in the Security Gateway sub-tab on the Network Devices Tab
You can specify multiple nodes with the Number of Nodes1 parameter in CDMA2000 and GPRS test cases. When you provision multiple nodes, the MN sessions are spread evenly among them.
In the GGSN Nodal test case, you can enable the node with the Security Gateway checkbox.
The number of tunnels supported by the LNS Node test case is defined with the Number of Tunnels1 parameter. One tunnel should be provisioned for every LAC that will attempt to establish a tunnel with the node.
If Unprotected Interface is enabled on the Security Gateway Node test case, an Unprotected Node becomes available for input. This Gateway Node will forward decrypted packets towards the Network Host without any VLAN Id.
Tcl Parameter: NetworkHostAddrLocal
Tcl Parameter: UnprotectedNodeAddr
With an Ethernet node, you can define:
The IP address and routing options... The Starting IP will increment for each node.
The MAC Address to override the Hardware MAC address so the packets sent out of the interface will use the provisioned MAC address rather the Hardware MAC Address.
The Outbound Traffic Port to disable the normal routing function and to force packets out of the selected interface.
Custom port selection... and error injection with the Advanced... button.
The L2TP Node report tab displays the processing measurements for the gateway nodes.
1 Maximum rates, number of sessions, and number of emulated nodes vary depending on the test configuration and the test system's licensed capacity.
