You can't.  The IP number is taken from the TCP socket, and the TCP
socket from your server originates with your server's IP number.
You can't fake it.  If you tried, then the response to your TCP SYN
("open connection") would go to the user's computer, which would
refuse it.

Then they're probably doing it on purpose, because they don't want
you using their server this way.  I suppose you could talk to them,
though; they might be doing it to prevent DoS attacks, in which
case they might willing to make some sort of arrangement.
