Re: KNOW MI WAN IP WITH C#

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

You may create a webservice that'll return client's IP and use "wsdl"
command to generate proper C# class for you if you want.

Or create a plain ASP/ASP.NET page that'll return client's IP, and use
webclient class to read it.

There're many ways to implement it.
