    I have the following configuration

    Internet <-->Modem (NAT)<-->(NAT ETH01) ZS (NAT ETH00)<--> FTP Server

    As you can see, there is a lot of NAT…

    My modem (provided by my ISP) is NATed (
    ETH01 I had to make it NATed so my users could reach the Internet
    ETH00 I had to make it NATed too, so my FTP server ( could be reached from the internet…

    To reach my FTP server from outside I forward the port 21 in the Modem to the ZS box and the I use the “Virtual Server” configuration:
    ETH01 / ANY TCP 21

    The problem with this configuration is that every request in the FTP server is logged as my ZS box IP (… for security purposes this is bad.. I can’t even use the autoban in the FTP server.

    Do you have any ideas?, or a better way to reach my Server from outside.

    The restrictions are that I cant put my server in the subnet 192.168.0.X it has to be in 192.168.1.X

    Any ideas would be great.. Thank you!


    Simply disable NAT on eth0. You don`t need it to access FTP server from internet. This work do port forwarding. Don`t forget to configure default gateway on FTP server.
