TOR_PT_EXIT_ON_STDIN_CLOSE=1

+ "TOR_PT_OUTBOUND_BIND_ADDRESS" + + Specifies an IP address that the PT proxy or server SHOULD use as source + address for outgoing IP connections. This feature allows people with multiple + network interfaces to specify explicitly which interface they prefer the PT to + use. + + If this value is unset or empty the PT MUST use the default source + address for outgoing connections. + + This setting MUST be ignored for connections to + loopback addresses (127.0.0.0/8 and [::1]). + + IPv6 addresses MUST always be wrapped in square brackets. + + Example with IPv4: + + TOR_PT_OUTBOUND_BIND_ADDRESS=203.0.113.4 + + Example with IPv6: + + TOR_PT_OUTBOUND_BIND_ADDRESS=[2001:db8::4] + 3.2.2.
