# The server ports are listed here. These are separated by spaces or commas.
# Each port is a colon separated list of values, which must include a
# port number. The order is irrelevant. Other options are
# ipv4 - Use IPv4 (default)
# ipv6 - Use IPv6
# tr-in - Transparent inbound.
# tr-out - Transparent outbound.
# tr-full - Fully transparent (inbound and outbound).
# tr-pass - Transparently Pass-through non-HTTP traffic (in conjuction with tr-in).
# ssl - SSL terminated port.
# blind - Blind tunnel port (CONNECT only)
# ip-in=[addr] - Bind inbound IP address (listen for client).
# ip-out=[addr] - Bind outbound IP address (connect to origin server).
# ip-resolve=[style] - Set the IP resolution style.
#
# Note - address types must agree with each other and the ipv4/ipv6
# option if specified. IPv6 addresses must be enclosed in brackets.
# ip-out can be repeated as long as each address is a different
# family. If ip-in is specified as an IPv6 address, the port is
# forced to IPv6. Transparent ports cannot be bound to an IP
# address on the transparent side.
#
# The '=' is optional for any option with a value.
#
# Example 1: Port 8080 IPv6 inbound transparent, and port 80 IPv4
# "8080:ipv6:tr-in 80"
#
# Example 2: Listen on standard http and https ports for IPv4 and IPv6,
# fully transparent on the http ports. Also provide an non-transparent
# port at address 192.168.1.56 on port 8080.
