This testvar’s default value is computed dynamically and may not always be the value below. Please see the testvar’s description for details.
This parameter specifies the IP address the DUT will use as its NAT source address. This is typically the same as the IP address assigned by CDRouter to the DUT’s WAN interface. A different expected NAT IP address can be specified to support other test topologies. When PPTP or L2TP are used as the WAN connection mode, this value should be updated to match the DUT’s PPTP or L2TP client tunnel endpoint IP address.
If not defined, this testvar defaults to the next address after wanIspIp. For example, if wanIspIp is 188.8.131.52 then wanNatIp would default to 184.108.40.206.
