Data forwarding between CP and UP

There can be situations where the CP receives UP data packets that need to be forwarded to the UP. This means that FortiOS can receive PFCP and GTP-U packets on the same interface and FortiOS Carrier allows you to add a GTP and a PFCP profile to the same firewall policy, or to use separate firewall policies to filter PFCP and GTP traffic.

FortiOS Carrier also allows UP data packets encapsulated in GTP-U that traverse the Sxa or Sxb (4G CUPS) or N4 interface (5G Core). UP data packets encapsulated in GTP-U that traverse Sxx or N4 interfaces include F-TEID for unique identity.
