Calico BPF dataplane doesn't support SCTP https://docs.tigera.io/calico/latest/operations/ebpf/enabling-ebpf#not-supported Clilcim support SCTP in beta https://docs.cilium.io/en/latest/configuration/sctp/

SCTP need for connection between gnb and AMF

mbaran0v commented 9 months ago

after testing with Cilium, we have:

open5gs core start and works
gnb connects to AMF successfully
ue connects to upf and get IP address
traffic from UE doesn't pass to internet

# cilium monitor -t drop
