Should nmap show ports?

[TinMan11]

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
