Question how to probe for open ports on a portable router?

[luv2liv]

this is the portable cellular modem/router i have https://www.sierrawireless.com/products-and-solutions/routers-gateways/gx450/
i plug my laptop in and get online anywhere in remote shelters. the router has a page to configure in this format http://192.168.13.10:8000
it is a very specific port! the problem is that I forgot the exact port number. is there a program that can scan for it?
I have tried "Advanced Port Scanner" and that did not list any open ports on my router.
my last open is to reset the router to default but i would lose all my settings and that would suck.

Googling the model number came back with this: sierra wireless gx450 default ip

Download kali linux if you are on windows as I do not know if there is a windows version (you can run kali as a live DVD/usb, or at least, you could at one point). That said, if you can only connect via wifi and don't have a wired connection, your wifi network card needs to be supported properly to perform network scans (i.e. it needs support for promiscuous mode, which not all drivers for cards support because many cards do not have support from their vendors for linux drivers and people had to reverse engineer drivers which "work").

ShieldsUP!

ShieldsUP!

That would only work if the port is open on and internet facing side, which in the case of most gear like consumer home wifi routers, the port is only open on the LAN side of the device to help prevent remote hacking.
