> I don't think this is needed, I prefer keeping in general 1 IP address per object unless it's really required to have more. If you want to be able to run GTP on the same machine, the way I'd recommend is setting 2 IP addresses on the slave machine running them and then set up ENB to use addres A and the run node to run the EPC use address B. This way we keep classes and number of attributes simpler and it's simply a matter of being smart when setting the addresses in the machine and resources.conf.

What you suggest is possible when using UHD as RF between UE and eNB. But not if you are using ZMQ. The eNB needs to have two configurable addresses in this case. If I configure a localhost address as enb.addr, this address will be used by the UE's ZMQ driver to connect to. This is of course not possible. So IMHO, having a addr (for ZMQ radio) and a bind_addr is actually more clear.
