Then when i show smf file config as an example we have :

If 192.188.0.0/16 is public address range then when i try to ping 192.188.2.2
root@free5g:~/go/src/free5gc/config# ping 192.188.2.2
PING 192.188.2.2 (192.188.2.2) 56(84) bytes of data.

64 bytes from 192.188.2.2: icmp_seq=2 ttl=46 time=97.3 ms
It work BUT if i do ping 192.188.2.3 or 192.188.2.4 (.5.6.7) it doesn’t work

Also when I try to capture traffic by wireshark it doesn’t show me the http2 protocol and in webconsole it fail to Registered UE Request

THANK YOU SO MUCH FOR YOUR SUPPORT

#5

For the first problem, it is same as the issue

#6

For this problem, why are you except to ping an public IP that are not control by you and expect to be working?

#7

You can try to capture the interface “any” because we do not know which interface are you used to bind at.

#4

when i do Test Registration, it show me this also :
