Prezados,

Solicito gentilmente ajuda com a configuração do Modem, Roteador e configuração do ProFTPd. Estou utilizando o servidor ProFTPd, no Linux Mint, mas não consigo acessar o servidor pela internet, por meio do endereço ftp://meu.ip.externo:2181, apenas consigo com meu ip interto que é: ftp://192.168.0.107:2181. Estou conectado com um modem telsec que fornece acesso ao meu roteador Dir600. O modem roteador e ProFTPd estão configurados da seguinte forma:

Configuração do Modem:


Configuração Roteador:


Configuração do ProFTPd:

#

# /etc/proftpd/proftpd.conf -- This is a basic ProFTPD configuration file.

# To really apply changes reload proftpd after modifications.

#



# Includes DSO modules

Include /etc/proftpd/modules.conf



# Set off to disable IPv6 support which is annoying on IPv4 only boxes.

UseIPv6                         on

# If set on you can experience a longer connection delay in many cases.
