I am not able to use netsh routing commands on WIndows 7. These commands work on Windows XP. Upon research I found that Windows 7 does not support routing commands. On Vista there was workaround by using "netsh add helper ipmontr.dll" and "netsh add helper ippromon.dll" but these commands does not work on Windows 7.
Can anyone help me to setup NAT on Windows 7. One more question, if NAT is disabled on WIndows 7, How does VirtualBox use NAT for guest PC to communicate with Host PC network machines.
