Is it possible to route GTP traffic in Linux?

I want to be able to route GTP-U traffic that arrives to my linux through two different interfaces. However, I want to route it using information inside the tunnel: inner ip addresses. My machine is not generating the GTP-U traffic, just a point in between. Is it possible to route GTP traffic in Linux using route, iptables or a similar approach? All I could find on this topic is and old GitHub repo that it is obsolet for Ubuntu 22 and higher.
