# address of the machine using the setting below. This will result in
# all host candidates (which normally have a private IP address) to
# be rewritten with the public address provided in the settings. As
# such, use the option with caution and only if you know what you're doing.
# Multiple public IP addresses can be specified as a comma separated list
# if the sfu is deployed in a DMZ between two 1-1 NAT for internal and
# external users.
