Welcome to GTP-Guard

GTP-Guard is a routing software written in C. The main goal of this project is to provide robust and secure implementation of GTP protocol (GPRS Tunneling Protocol). GTP is widely used for data-plane in mobile Core-Network. GTP-Guard is implementing pGW features for 4G and UPF features for 5G Core-Networks. GTP-Guard is acticulated around a set of 3 main frameworks. The first one offers a Proxy feature for data-plane tweaking. The second one is a Routing facility to inter-connect, encapsulates or provides any routing related. The last one is a Firewall feature offering filtering, rewriting, redirecting. GTP-Guard relies on Linux Kernel XDP framework for its data-plane using eBPF programs. Administration and user-level interface are available via a standard VTY terminal interface.
