To do that, your router needs to support UPnP (Universal Plug-n-Play), and 
you need to have the UPnP client files installed on each PC.  Refer to MSDN 
for more information:

Those functions have nothing to do with what you are asking for.  They 
manipulate the calling PC's local routing table, but you need to adjust the 
router's table instead.
