Newbie ip address question

[GVP]

Greetings,
New to xampp, so forgive me if this is an obvious question.

I am trying to replicate in php, a Delphi program that I wrote. The program accesses a remote server, and this server requires ip authentication before granting access. I have a static ip address, and my Delphi program works fine.

However, I cannot get the php version, running under xampp on my pc, to get access. My question is, is the remote server seeing my login attempt as coming from my true ip address, or is it coming from localhost? If so, is there a way around this?

Hope I've explained this satisfactorily - thanks in advance

GVP.

Do you have some logs from your remote system?
Are there any errormessages?

[GVP]

No, unfortunately I am only able to receive data as it is a third party server and I have no other access to it. However, I do get a response from the remote server - which would seem to indicate the physical connection is being made - but the fact that I can't get logged in seems to indicate that is the part that's failing. Unfortunately, the remote server's response is simply a true or false flag - no actual message...

What does you mean with "true ip address"?

[GVP]

I mean the actual static ip address issued by my isp. The remote server is expecting me to access from that ip. I'm wondering if by running my php program in xampp on my pc, that the remote server is seeing the access request as coming from something else, such as localhost?

I mean the actual static ip address issued by my isp.

This static IP is assigned to a:
- NAT router
- a HTTP proxy (are you talking about HTTP requests?)
- a local network interface
?
