I would recommend you to take a look at Internet Gateway (implements simple NAT solution), LAN HTTP Monitor (implements HTTP redirector and HTTP proxy).

Actually Internet Gateway implements topic number 1. It allows one system to share Internet to several other systems.

Topic number 2 can be implemented sing techniques demonstrated by LAN HTTP Monitor. Instead of redirecting to proxy you can redirect to your own HTTP authentication page.

Topic 3 is an easy addition to previous ones.

Thanks for your nice post , i will start right now with studying these examples ,but what is the prerequisites for being professional in this field and create strong application

Besides programming skills it would be nice to have a strong knowledge of TCP/IP networks.

dear SerpentFly thank you very much ,
but i have another question is it possible o implement this souloution using c# dll waraper as i have good experince in c# but i have littel experince in c++

[Vadim Smirnov]

Yes of course, this is possible. And we have customers who built their solutions using C#. Personally because of strong type control in C# I find it not that convenient when parsing packet protocol headers.
