XML Package and IP Address

I have been developing an online payment system using classic ASP
which uses
Msxml2.ServerXMLHTTP to submit an XML package to a 3rd party payment
system. The website the payment system is part of is one of many on a
Server 2000 / IIS5.0 installation. Each web site on my server has its
own IP address. The 3rd party payment system is hosted on another
server not under my control.

The issue I have is that when the XML package is submitted, the 3rd
party system is not registering the correct IP addresss for the
originating request from the website, it is registering the 'Core' or
first IP address on the server. The originating IP address is part of
their authentication model and so the XML submission is failing
because the wrong IP address is being passed through.

Any ideas why the wrong IP address is being passed?

Any pointers on what to do next as far as testing goes?

Thanks in advance for any assistance.

I don't think there is much you can do about that. The IP address isn't
wrong. The TCP/IP stack is completely ignorant of any assignment of IP
address to websites that is configured in IIS.

Re: XML Package and IP Address

I don't know if you're ISP supports it, but it is possible to query a
socket for the IP address used in the connection. Alternatively, you
could grab the outgoing IP address from a site like IPCHICKEN.COM or
something to stick in your XML data.
