necessary to capture the FTP control connection.
+.It Fl R Ar address:[port]
+Reverse proxy mode for FTP servers running behind a NAT gateway.
+In this mode, no redirection is needed.
+The proxy is run from
+.Xr inetd 8
+on the port that external clients connect to (usually 21).
+Control connections and passive data connections are forwarded

.It Fl r
Use reverse host

lookups for logging and libwrap use.
By default,
the proxy does not look up hostnames for libwrap or logging purposes.
+.It Fl S Ar address
+Source address to use for data connections made by the proxy.
+Useful when there are multiple addresses (aliases) available
+to the proxy.
+Clients may expect data connections to have the same source
+address as the control connections, and reject or drop other
+connections.
.It Fl t Ar timeout
Specifies a timeout, in seconds.
The proxy will exit and close open connections if it sees no data
