>Description:
We can do inbound or outbound proxy of ftp connections with ftp-proxy(8). But the /etc/rc.d/ftp-proxy just allow one instance of the proxy.
If we need to run an inbound **AND** outbound proxy, we need two instances of ftp-proxy. So I have modified the /etc/rc.d/ftpproxy and /etc/rc.conf to allow more than one instance.
We can add at /etc/rc.conf some variables:
ftpproxy_exec="exec1 exec2 execN"
ftpproxy_exec1=""
ftpproxy_exec2=-p8010 -R ftpserverhost
ftpproxy_execN="-p8020"
The var 'ftpproxy_exec' is a list with the instance names, the script (/etc/rc.d/ftp-proxy) will search for the vars 'ftpproxy_{LIST_ITEM}'
The 'ftpproxy_{LIST_ITEM}' will contain the same thing that normally contains the 'ftpproxy_flags' var, or a empty string.
