Virtual Local IP
by Haicheng Wang

  VLIP is a win32 based software that is able to virtually change local IP address for a specified program. This software is able to simulate a public IP address to a workstation in a LAN. Your PC seems to directly connect to Internet, without any limitation of LAN.

VLIP is able to solve many problems of Internet applications working within a LAN:
Build a FTP Server within LAN - can't use passive mode
Using a FTP Client within LAN - can't use active mode
Using Chat software with full features (file transfer, video chat etc) in LAN
Overcome some spam-checker for Email Client in LAN
Increasing speed of Peer to Peer downloading software in LAN

Features:
Load a win32 based program and change result of WIN32 API function bind, gethostbyname and gethostname.
Change both host name and IP address of local machine for loaded program.
Change local IP address to specified value for all sub processes/inherited processes of target program. For example, if VLIP loaded program A, program A loaded program B, then VLIP also affects program B.
Automatically get IP address of NAT (Router/Proxy server) by programmable VB script.
Save settings of specified program to a shortcut.
VLIP is developed with win32sdk so it is tiny and fast.
