Two things trying to be achieved, Firstly WAN ftp access on a different port aside from 21, it appears if changed to something else than 21 then the directories are not listed despite a login is attempted. Port 21 seems to work fine, I guess I could edit the iptables for this? Second is for allowing any IP, ive tried 0.0.0.0/0 which removes the /0. I'm fully aware of what this does and I will be having multiple dynamic ip's for a short duration and nothing crucial is on the device/network. Is the syntax different for allowing any with vsftpd? I checked the iptables for this as well and tried to manually apply the change and reload the firewall but it just corrects the entry and appears to not work.
