Hi..
I want to integrate custom payment gateway in my site. Iam using nopcommerce 2.2 version. API what payment provider has given is in .net2.0 version.
Process is that, we have to send order details to the url they have given for payment. When payment completes, it will redirect to our site. In  this code  "HttpContext.Current.Request.UserHostAddress" we shoud get the ip address of the patment gateway site, but its not giving IP address of payment gateway server, Its giving IP address of local server. Also they are passing some parameters like status of payment, track Id and all through query string. But these values also not getting in our site.
Can anybody please help me to get the querystring values in our site .

Thank you
