Hello,
If you have multiple network cards, multiple connections to internet or you are using a VPN and you want that some of your traffic goes out by using a specific interface; then you will need the “route” command!
As easy as this:
route -p add [destiny.ip] [gateway] if [interface.number]
For example:
route -p add 209.68.27.16 192.168.1.1
If the name resolve using netbios you have to add the interface number, ex:
route -p add 209.68.27.16 192.168.1.1 if 32
[seems that windows networking takes a different route and wont work with the default route]
You can get the interface number with this command:
route PRINT -4
[its the fist output, labeled as “Interface List”]
And delete a created route with:
route -p delete 209.68.27.16
