    Perhaps a silly/stupid question, but when I run an nmap scan from an external source, not all of my open port forwards show up.

    Should they?

    I have confirmed they are in /temp/nat_rules.

    Thanks in advance.

    To show as open there needs to be a service listening and responding on that port as well as the forwarding rule being present.

    Ok thanks. There is a service listening. WebDAV to be exact.

    Thanks
