    I'm trying to get a grasp at my router (RT-AC68U) and this firmware (v380.65) by playing around. The final goal is a super paranoid setup, but only for educational purpose.

    I'm trying to bind sshd and httpds to a specific device (a vlan). Sshd works, but I don't geht how I can change httpds.

    I try to create a vlan (vlan9) that shall be used in my lan for admin/config purposes only with all admin interfaced attached only to this vlan. I did so far:

    # my computer:; router, direclty connected, no switch (yet)

    # change switch config
    robocfg vlan 9 ports "4t 5t"

    # change router config
    vconfig add eth0 9
    ifconfig vlan9 netmask
    ifconfig vlan9 up

    # allow traffic in firewall
    iptables -A INPUT -i vlan9 -m state --state NEW -j ACCEPT

    # i can add another sshd on the new interface by simply typing
    dropbear -p -s -j -k

    # i succeed to connect from my computer after bringing up the vlan9
    # (and plugging the cable into router port 4)
    # top shows that the new process listening on the vlan spawns subprocesses if I login
    vconfig add eth0 9
    ifconfig eth0.9
    ifconfig eth0.9 up

    # but the same doesn't work for httpds:
    httpds -s -p 8443 -i vlan9
    # it exits immediately with this message:
    [ssl_init] success
    bind: address already in use
    can't bind to loopback address

    # So I guess I can only run one instance, so I kill httpds manually and restart it immediately, due to the automatic restarts
    kill [pid of running httpds] && httpds -s -p 8443 -i vlan9
    # this kinds works, the webbrowser can now connect from computer, but it doesn't deliver content, I only get an 404 on the browser of the computer. Please note that the connection seems to work, I do get the 404, and the ssh connections though the vlan9 is working.

    So I have a couple of questions regarding to this:
    How can I get httpds to deliver the webui on a second interface?
    How can I control the automatic restart of the webgui?
    Maybe in general, where is the config for the httpds service and how is it (re)started.

    I would be very thankful if someone got a few minutes and pointed me in the right direction or to the right docs :)
