10 months ago Hi,
I confirmed that FTUP works with Open5GS on 120-upf-ftup-fteid branch.
The config.yml in that case is as follows. N3 and N4 addresses are different.
interface_name: [enp0s9, enp0s16]
xdp_attach_mode: generic
api_address: :8080
pfcp_address: 192.168.14.151:8805
pfcp_node_id: 192.168.14.151
metrics_address: :9090
n3_address: 192.168.13.151
qer_map_size: 1024
far_map_size: 1024
pdr_map_size: 1024
resize_ebpf_maps: false
heartbeat_retries: 3
heartbeat_interval: 5
heartbeat_timeout: 5
logging_level: info
feature_ueip: true
feature_ftup: true
ip_pool: 10.45.0.0/16
teid_pool: 65536At that time, I modified the following and built eupf.

}Thank you very much!

Hi,
When I applied this Pull Request and tried to work with free5GC, the following error occurred on free5GC. Also, N3 and N4 are different addresses. I don't think free5GC supports FTUP, so first I tried to confirm the current behavior that is not FTUP.
FYI.
