[srslte-users] Internet connection with ZeroMQ setting

[Andre Puschmann]

Kentaro,

please double check the interface names and addresses you use in your
setup. The issue is likely a routing/forwarding one. Also the network
namespace routing could play a role here.

But there is no fundamental issue with what you're trying to achieve.

Cheers
Andre
