The netsh default for Windows 2003 does not have the ability to set port mappings, it needs to install the next IPv6 protocol, how to install it? Locate the local connection right-click property to add a new protocol, restart the system after installation, and then use the Port Mapping command for Windows:
netsh interface portproxy add v4tov4 listenport=n3 connectaddress=hostd_ip connectport=n2
netsh interface portproxy Show all
Set all connections to local 1433 ports to the 1433 port of 192.168.22.2
C:\Documents and Settings\sincoder>netsh interface portproxy add v4tov4 Liste
nport=1433 connectaddress=192.168.22.2 connectport=1433
C:\Documents and Settings\sincoder>netsh interface portproxy Show All
