Greetings,
Couldn’t find an answer to this in the forums already but I wanted to resolve a nagging question in the back of my mind.
I have an SXT LTE6 kit as my main internet connection. This has the ether1 interface setup as a passthrough to a Hex S router. All is working great, but I haven’t been able to figure out what if any firewall I should setup on the SXT device. Because it’s doing passthrough, am I safe with no firewall setup at all on the SXT, and rely on the firewall in the Hex S as my frontline defence?
It would appear that the LTE is simply used to apply modem type parameters (to verify traffic coming over assigned IP is legit)?
In any case not sure of the purpose, but it doesnt look like the LTE is doing anything special.
However you have to be able to login to the device and you want that capability to be secure and from your router and not the internet.
Hmmmm…
Is there a default config from the LTE when you first login… that may give some clues…
When you use your LTE device in passthrough mode, then the LTE device is responsible only for the Modem settings…
It does not have internet itself, but instead it needs your Router to access the internet i.e. the device that the passthrough is going to.
So, no, you don’t need firewall on the LTE device when passthrough mode is active.
