# Example coturn configuration for BigBlueButton
|
||
|
|
|
||
|
|
# These are the two network ports used by the TURN server which the client
|
||
|
|
# may connect to. We enable the standard unencrypted port 3478 for STUN,
|
||
|
|
listening-port=3478
|
||
|
|
|
||
|
|
# and since TLS over SMTP port (465) is now blocked by major browser vendors,
|
||
|
|
# we reverted to the most common coturn TLS port 5349, which has limitations
|
||
|
|
# in restrictive firewall environments. For maximum client support run
|
||
|
|
# coturn on a dedicated host on port 443.
|
||
|
|
tls-listening-port=5349
|
||
|
|
|
||
|
|
# If the server has multiple IP addresses, you may wish to limit which
|
||
|
|
# addresses coturn is using. Do that by setting this option (it can be
|
||
|
|
# specified multiple times). The default is to listen on all addresses.
|
||
|
|
# You do not normally need to set this option.
|
||
|
|
#listening-ip=172.17.19.101
|
||
|
|
|
||
|
|
# If the server is behind NAT, you need to specify the external IP address.
|
||
|
|
# If there is only one external address, specify it like this:
|
||
|
|
#external-ip=172.17.19.120
|
||
|
|
# If you have multiple external addresses, you have to specify which
|
||
|
|
# internal address each corresponds to, like this. The first address is the
|
||
|
|
# external ip, and the second address is the corresponding internal IP.
|
||
|
|
#external-ip=172.17.19.131/10.0.0.11
