[asterisk-users] asterisk server - no sound

[andre castro]

Any ideas.
After configuring  port forwarding on the server (machine making nat) to
forward connections originated from external clients to the machine
running asterisk, as explained in
https://www.voip-info.org/wiki/view/port+forwarding
My peers were unable to register.


And When running Asterisk I am getting:
No ethernet interface found for seeding global EID. You will have to set
it manually.
Unable to access the running directory (No such file or directory).
Changing to '/' for compatibility.

Any advice what to do next?

thanks
a
