About This Guide

Use this guide to configure General Packet Radio Switching (GPRS) Tunneling Protocol (GTP) and Stream Control Transmission Protocol (SCTP) in Junos OS on the SRX Series devices to secure GTP and SCTP traffic flow to external networks. The GTP firewall features such as policy-based GTP, GTP inspection, and GTP handover techniques address key security issues in mobile operators networks.
