GTP firewall service to block or allow GTP-C v1 messages from specific SGSN/GGSN and GTP-C v2 messages from specific SGW/PGW to prevent fraudulent activity occurring from any specific serving node or home node. GTP Traffic from specific SGSN (3G) or SGW (4G) can be blocked going to specific home operator, including 3G GSM to 4G LTE and 4G LTE to 3G GSM protocol interoperability provided by GTP Firewall. Individual Information Elements within GTP-C v1 and GTP-C v2 messages will be monitored based on home and serve operator configuration as well as GTP messages and Information Elements mapped from GTP-C v1 to GTP-C v2 for 3G GSM to 4G LTE interoperability and GTP-C v2 to GTP-C v1 for 4G LTE to 3G GSM interoperability.
