    Help with a moderate networking issue


    I am wanting to make traffic pass through my computer to another computer.


    Here is my network setup:

    [WAN] > [MODEM] > [10.1.1.3] > [192.168.56.101]


    How can I make my computer ([10.1.1.3]) forward incoming traffic on port 25 to another computer ([192.168.56.101])?

    That did not solve my issue.

    sudo echo 1 > /proc/sys/net/ipv4/ip_forward
    bash: /proc/sys/net/ipv4/ip_forward: Permission denied

    Why do you think you got permissions denied?
    You need to be root to do this.
    So yes, this is the fix.
