    Hello,

    I am new to Zeroshell, the software caught my eye due to its routing capabilities, but I am having a hard time understanding how to configure it. Please note that I know just enough routing to make me dangerous 😳

    I have a Cable conneciton, within the connection, the ISP has provided me a static CIDR block of 16 IP’s, and 1 static address, what they are calling, “WAN IP” address.

    I was wondering if I can get some help on configuring Zeroshell.

    The IP information is as follows:
    “WAN IP” 98.xxx.xx.249
    “WAN GW” 98.xxx.xx.241
    “WAN Netmask” 255.255.255.240

    CIDR Block: 174.xx.xx.112/28

    The only assistance that I have received from them, is that 174.xx.xx.112 is the “Network Address”, 174.xx.xx.127 is the “Broadcast Address”, and they suggested to use 174.xx.xx.113 as the Gateway. They want to sell me managed router services, but the price will be way to much, which is why I am hoping Zersoshell can be used.

    My network topolgy is as follows:

    Internet < --> Cable Modem < -->Zeroshell (3 Nic) < --> Astaro Firewall (3 Nic)< --> Internal LAN

    I have Zeroshell installed (via live CD), on an old Dell Deminsion PIII 750 Mhz computer.

    Thanks

    Hello,

    I went ahead and configured Zeroshell as shown below:

    internetcable modemNic1[Zeroshell]Nic2client01

    Nic1: IP Address: 98…249
    Netmask: 255.255.25.240
    GW Address: 98…241
    Nic2: IP Address: 174…113/28
    No Gateway??? Is this correct?

    Client01: IP Address: 174…114/28
    GW Address: 174…113

    The problem that I am having is the following:
    1. client01 can ping 174…113, ping 98…249, but fails pinging GW 98…241.
    2. client01 can not get on the internet, unless NAT is enabled.

    From Zeroshell “shell”, I can ping the internet, ping the GW, ping Nic1, and client01.

    My goal is to use Zeroshell as a basic router. Not sure what I am doing wrong.

    Thanks for your help.

    I can speak a little ?…. Astaro Firewall enhances security of your network?
