Yes, this is possible to implement in Visual basic using WinpkFilter library, however I can’t provide you with ready to use code in VB (as I’m not a VB coder). If you can use the C code I think I can provide some.
Also you can use port/protocol mapping avalable in NeT Firewall (set up redirector rules on the internal LAN interface).
Can you provide some C code for this purpose ?
