    Hi All,
    Could anyone give me some tips on how to connect to my project remotely. Unable to connect unless via home WiFi. Is it something to do with router settings and port forwarding? Please excuse my ignorance on the tech side. Obviously I don't have a clue - so your help would be much appreciated :).

    Port forward port 80 to the ip address of the shac or the additional port specified under system/services HTTP server.

    You will also need either a static external ip address, or use a dynamic dns provider like dynDNS that will map a dedicated URL to your dymanic ip address. Just google "remotely accessing home devices"

    All sorted for the hacker waiting at your door ;-)
    I would not set your additional port on http, use https, install a cert and make it a real complex password. Don't use admin, complex the hell out of that password and don't use it (at least until Schneider allow disabling or renaming that user)

    Hi All,

    I'm in the exact same position as the original poster to this thread.
    I have a 5500SHAC which I can access via my local wireless router at home, but not remotely.
    The SHAC has a fixed IP and the ports have been setup as shown in the below screenshot:

    The SHAC is patched via ethernet into a 'D-Link DWR-921' router with a 4g simcard inserted (internet connection has proven ok). I've registered a hostname with 'no-ip.com'. No-IP is available in the dropdown list for the router. The router has been setup DHCP.
    I have configured the router as shown below:

    The SHAC is currently powered via USB from my PC - could the USB connection be affecting things?
    Is there another better port worth trying?

    If anyone could offer any advice that would be great.

    Thanks

    I'd be REALLY reluctant to expose the SHAC to open intawebs, they don't have recent firmware on them so a number of vulnerabilities may be present.

    VPN would be a far superior access method.

    +1 for VPN or even an app something like splashtop.

    Opening ports on something without a datacenter grade, correctly configure UTM is not a good idea.

    Thanks for the advice.
    I'll have a look into Splashtop, that looks pretty good.
