# The Docker network that Coturn would be put into.
#
# Because Coturn relays traffic to unvalidated IP addresses,
# using a dedicated network, isolated from other Docker (and local) services is preferrable.
#
# Setting up deny/allow rules with `matrix_coturn_allowed_peer_ips`/`matrix_coturn_denied_peer_ips` is also
# possible for achieving such isolation, but is more complicated due to the dynamic nature of Docker networking.
