# Auxiliary STUN/TURN server listening endpoint.
# Aux servers have almost full TURN and STUN functionality.
# The (minor) limitations are:
#
# 1) Auxiliary servers do not have alternative ports and
# they do not support STUN RFC 5780 functionality (CHANGE REQUEST).
#
# 2) Auxiliary servers also are never returning ALTERNATIVE-SERVER reply.
# 
# Valid formats are 1.2.3.4:5555 for IPv4 and [1:2::3:4]:5555 for IPv6.

# Output: 0xbc807ee29df3c9ffa736523fb2c4e8ee
# ('0x' in the beginning of the key is what differentiates the key from
# password. If it has 0x then it is a key, otherwise it is a password).

# The corresponding user account entry in the config file will be:

# Option to set the log file name.
# By default, the turnserver tries to open a log file in 
# /var/log, /var/tmp, /tmp and current directories directories
# (which open operation succeeds first that file will be used).
# With this option you can set the definite log file name.
# The special names are "stdout" and "-" - they will force everything 
# to the stdout. Also, the "syslog" name will force everything to
# the system log (syslog). 
# In the runtime, the logfile can be reset with the SIGHUP signal 
# to the turnserver process.
#
#log-file=/var/tmp/turn.log

# Option to redirect all log output into system log (syslog).
#

# This flag means that no log file rollover will be used, and the log file
# name will be constructed as-is, without PID and date appendage.
# This option can be used, for example, together with the logrotate tool.
#
#simple-log

# Option to set the "redirection" mode. The value of this option
# will be the address of the alternate server for UDP & TCP service in form of 
# <ip>[:<port>]. The server will send this value in the attribute
# ALTERNATE-SERVER, with error 300, on ALLOCATE request, to the client.
# Client will receive only values with the same address family
# as the client network endpoint address family. 
# See RFC 5389 and RFC 5766 for ALTERNATE-SERVER functionality description. 
# The client must use the obtained value for subsequent TURN communications.
# If more than one --alternate-server options are provided, then the functionality
# can be more accurately described as "load-balancing" than a mere "redirection". 
# If the port number is omitted, then the default port 
# number 3478 for the UDP/TCP protocols will be used.
# Colon (:) characters in IPv6 addresses may conflict with the syntax of 
# the option. To alleviate this conflict, literal IPv6 addresses are enclosed 
# in square brackets in such resource identifiers, for example: 
# [2001:db8:85a3:8d3:1319:8a2e:370:7348]:3478 . 
# Multiple alternate servers can be set. They will be used in the
# round-robin manner. All servers in the pool are considered of equal weight and 
# the load will be distributed equally. For example, if we have 4 alternate servers, 
# then each server will receive 25% of ALLOCATE requests. A alternate TURN server 
# address can be used more than one time with the alternate-server option, so this 
# can emulate "weighting" of the servers.
#
# Examples: 
#alternate-server=1.2.3.4:5678
#alternate-server=11.22.33.44:56789
#alternate-server=5.6.7.8
#alternate-server=[2001:db8:85a3:8d3:1319:8a2e:370:7348]:3478
			
# Option to set alternative server for TLS & DTLS services in form of 
# <ip>:<port>. If the port number is omitted, then the default port 
# number 5349 for the TLS/DTLS protocols will be used. See the previous 
# option for the functionality description.
#
# Examples: 
#tls-alternate-server=1.2.3.4:5678
#tls-alternate-server=11.22.33.44:56789

# Option to set the max time, in seconds, allowed for full allocation establishment.

#
#max-allocate-timeout=60

# Option to allow or ban specific ip addresses or ranges of ip addresses. 
# If an ip address is specified as both allowed and denied, then the ip address is 
# considered to be allowed. This is useful when you wish to ban a range of ip 
# addresses, except for a few specific ips within that range.
#
# This can be used when you do not want users of the turn server to be able to access
# machines reachable by the turn server, but would otherwise be unreachable from the
