## IP addresses and ports to listen to, as well as their external IP
|
|
## If there is no NAT involved, `local` and `external` can be the same.
|
|
## As many addresses as needed can be configured here, IPv4 and/or IPv6.
|
|
## You should at least change the `external` IP address.
|
|
|

### Example with both IPv4 and IPv6 addresses:
|

# listen_addrs = [
