Using the HTTP server via TAP

[Peter Nguyen]

Hi,

So just to clarify, what I meant by the following:

Is that i was thinking that it might not be possible to get the starting IP
address from the web server when a HTTP request is received. I can obviously
obtain the IP address of the XP vm by looking at the network settings. What I
want to be able to do is obtain the IP address of the actual VM that made the
HTTP request to the web server while in the web server for experimental
purposes. I'm currently looking at some qemu documentation, and seeing if i can
glean anything out of it. I'm thinking that possibly the XP vm would have its
own tap device to the web server maybe?

Thanks
Peter
