Hello everyone,

I tried to follow this guide:

So I logged in remotely via Remote Configurator:

in a pair of FlexH firewalls of mine and click here:

and also on a cheaper model:

Anyway I am NOT able to have the CLI working, neither on Edge:

Or Chrome:

The only way to use the web CLI is when I am connected on the same subnet or having a static public IP that I can reach from the rest of the world.

So… am I forced to go onsite or have a PC remote connection or a VPN user to login on the firewall?

Is there a way to have it working properly also via Remote Configurator via Nebula?

The only option that I know I can use remotely (when I have no man onsite, no PC available and possible VPN) is to set a Policy:

to open a specific port for remote connection to ZyWALL, but this means that I'm forced to have a static public IP available and opening ports is NOT always possible (e.g. health organizations where to place a secondary network, under another ISP operator that filters some ports…).

I tried also this:

But it seems to have issues with some LTE (or other filtered) internet connections while Remote configurator works nicely.

Please let me know if it is a limitation by design.

    Hi @GiuseppeR

    The first issue is because the remote configurator only mapping HTTPS port for web GUI. I will report to our product team for enhancement.

    The second issue is because the ssh port is not allow on the H's security policy.

    Hi @Zyxel_Melen

    could I suggest also to add also a "logging to txt" export way on the web CLI?

    Otherwise you have to use PuTTY over Remote SSH and it is not always available to install on every machine 😁

    I also forward this suggest to our product team to evaluate it.
