我试图用Ubuntu 16.04服务器在家里configuration一个FTP服务器，但是PASV有一个问题。 我不能让它返回我的外部IP。
ftptesting仪的输出：

rsa_cert_file=/etc/ssl/private/vsftpd.pem rsa_private_key_file=/etc/ssl/private/vsftpd.pem ssl_enable=YES allow_anon_ssl=NO force_local_data_ssl=YES force_local_logins_ssl=YES ssl_tlsv1=YES ssl_sslv2=NO ssl_sslv3=NO require_ssl_reuse=NO ssl_ciphers=HIGH pasv_enable=Yes pasv_max_port=1050 pasv_min_port=1040 pasv_address=xx.xx.xx.xx <- my wan IP
使用pasv_address来configuration您的外部IP地址。
我为华硕RT-AC66U（WRT Merlin）使用了一个自定义路由器固件，并更新为昨天发布的新版本。 现在正在工作。
