Enables gateway ports. Remote hosts are allowed to connect to local forwarded ports. By default, Reflection Secure Shell binds local port forwardings to the loopback address (this is equivalent to using "localhost"). This prevents other remote hosts from connecting to forwarded ports. Allow gateway ports can be used to specify that Reflection Secure Shell should bind local port forwardings to the local ethernet address (such as an IP address, a URL, or a DNS name), thus allowing remote hosts to connect to forwarded ports.
Be careful about enabling this setting. Using it can reduce the security of your network and connection because it allows remote hosts to use the forwarded port on your system without authenticating.
