[srslte-users] srsenb can not connect to srsepc

[putaogan]

Dear,both
Thanks for your replys.
I change a Cloud Server which has a ubuntu system and supports SCTP, GTP, and it works.
A IP 172.16.0.1 generates in  the Cloud Server(srsepc) and another ip 172.168.0.2 generates in  the a computer(srsue) with a local network.
I try to ping one ip from another and it fails.
I don not know why.
Could you give me any idea ?
Thanks




Best regards,


Dongxu

For S1 connection, you will need to allow SCTP on port 36412 and GTP on port 2152.

Best regards,

Hey there,

Check that the firewall is correctly configured and allows communication such as SCTP, GTP and so on.
Those protocols are not commonly allowed to run through public IP interfaces by Cloud Providers.


Cheers,

Dear，all
I can  succeed in running srsenb and srsepc in two computers separately in a local network.
The ‘ping’ command shows that the delay is about 2 ms.
i want to run srsepc in a Cloud Server ,and run srsenb in a local computer which has a public ip .
I tested and failed.
The srsenb can not connect to srsepc and there is no any response in srsepc.
The ‘ping’ command shows that  delay is about 65 ms.
I am sure that the  Cloud Server and the local computer can get access each other.
I am doubet whether the delay between srsepc and srsenb is too long and affects the communication between srsenb and srsepc.
If you can give any suggestion，i will be grateful.




Regards
Dongxu
