There is a web service (in an Intranet environment) what checks the client IP and if it is not a valid IP then refuses the request. Is there any opportunity to cheat at this web service with the IP?
Thank you in advance.

It is prefectly possible to send IP packets with fake IP addresses. However, you won’t get a reply because the reply will be directed at the fake IP address. This means that you can’t establish TCP connections (upon which HTTP(S) depends) because they require two-way IP traffic.
