Description (partial)

The issue happened when there are 2 internet WAN links attached to the cEdge. Both WAN has NATed configured. Default route to VPN 0 is configured on the service VPN route.

When the tracker on the WAN 1 (internet) goes down, the PC Client on the service side still send some of the traffic to the WAN 1 even though the WAN 1 tracker is already down. 

The internet traffic is supposed to send out to WAN 2 (internet) only. This makes internet connection from the PC got interrupted. The logic here is that  if the tracker goes down, the cEdge should not send the NATed Traffic out on that interface at all

2 WAN Internet links doing NAT DIA both using static default route on service VPN
