Hello, I've been using ftpd behind a firewall for internet interface while it's running all ports open on sub-net of course.
I basically am using a redirect rule on the external interface so as not to keep port 21 open on the web this in pf.conf the following rule pass in on $ext_if proto tcp to port 30021 rdr-to 127.0.0.1 port 21 pass in on $ext_if proto tcp to port > 49151 Is this a correct way to do it ? It does work well, I have seen things about proxy, is it needed ? What would it change ? Regards
