command to achieve port forwarding (port mapping) After adding in batches, and view the mapping: netsh interface portproxy add v4tov4 listenport=701 connectaddress=192.168.157.130 connectport=701 netsh interface portproxy add v4tov4 listenport=2463 connectaddress=192.168.157.130 connectport=2468 netsh interface portproxy add v4tov4 listenport=1993 connectaddress= 192.168.157.130 connectport=1982 netsh interface portproxy add v4tov4 listenport=50003 connectaddress=192.168.157.130 connectport=55555 netsh interface portproxy show all cmd.exe cmd command execution



















View all port forwarding proxy parameters:

netsh interface portproxy show all

Example 1: single ip forwarding Forward the data of

the local 8080 port to the 8080 port on 192.168.56.101, or it can be forwarded to other external network ip to

add: netsh interface portproxy add v4tov4 listenport=8080 connectaddress=192.168.56.101 connectport=8080

Delete: netsh interface portproxy delete v4tov4 listenport=8080

Example 2: Double ip and multiple ip can use the following to

add an IPV4 to IPV4 port mapping, that is, specify an ip

to add: netsh interface portproxy add v4tov4 listenaddress=192.168.193.1 listenport=701 connectaddress=192.168.192.128 connectport=701 The

specified listening ip and port can be deleted

Delete : netsh interface portproxy delete v4tov4 listenaddress=192.168.193.1 listenport=701

-------- --------- Troubleshooting:

2003 xp system needs to install IPV6 (otherwise port forwarding is not available!) 2008 2012 system directly execute the above command

Installation command: netsh interface ipv6 install

Important Open IPv6 service: After installation, also open

Management Tools-Services-IPv6 Helper Service to start, otherwise, after mapping the port, it still cannot connect to

the win7 system . Used to disable the system firewall, the opposite command "netsh firewall set opmode enable" enables the firewall.
