MCORD with OAI eNB - SCTP issues

[Kostas]

Hi all,

Brief intro on my setup: 

- the MCORD instance (v6.0) is currently running in the cloud (CloudLab)

- I have installed the OAI eNB on an Intel NUC using LimeSDR for the RF 
- I have created a VPN using WireGuard (www.wireguard.com) between the eNB and the CloudLab and I'm using the wg0 interface for the connection with MME/SPGWu. I had tested also with OpenVPN but again had similar issues. Trying Wireguard because it is said to support SCTP.

When I try to run the lte-softmodem like this (as per OAI guide) I'm having issues setting up the SCTP connection. 

Any ideas/guidelines on how I could possibly get the connection up? 

The error:

Hi,

I have come across your post. I exactly have the same setup can you please let me know, has your setup finally worked?

Hi, naziajahan27, 

due to the license issue found in 6.0, we deleted the relative images, and we announced it last year.

Please try our new release https://guide.opencord.org/profiles/comac/.
