i don’t have a domain and i don’t think my ISP will agree.
that’s why i was looking for a solution around.
rextended’s idea of sending speedtest.net traffic only out of one line will work, but then a) you will have to maintain this list forever b) there may be other sites/applications that will reveal the same information. You are fighting a losing battle.
True.
But remember, each client have many way to know what ip have…
what about tracing, the tracert command how to make it go through specific wan interface ?
Windows tracert uses icmp echo requests, so that’s easy to filter out and route through the right interface.
But as others already suggested, you can’t win.
Linux traceroute uses udp and ports seem to be pretty much random. And there’s traceproto and it can use tcp with any port. So there’s basically nothing you can route through the second connection without the risk of its address being revealed. Even if you aimed at fooling only unskilled Windows users, there’s still possibility that any random website will show the address.
well i’m aiming at fooling unskilled windows users who thinks linux is another brand of computers such as macbook 
what about route filters over here? someone told me they can do it over cisco routers.
