[srsran-users] srsRAN 4G with ZMQ Using Two Linux PCs

[Robert Falkenberg]

Hi Chao-Hwa,

when running EPC/ENB and UE on different computers, the UE doesn’t need 
to create the gateway in an isolated network namespace. Just remove the 
|--gw.netns=ue1| part.
If you still want to use the network namespace, please create the 
namespace before starting the UE, see here 
<https://docs.srsran.com/projects/4g/en/latest/app_notes/source/zeromq/source/index.html?highlight=sudo%20ip%20netns%20add%20ue1#network-namespace-creation>.

Best regards,
Robert
