openssh server remote access

[Semih Ozlem]

I am unable to access my modem settings page when writing 192.168.1.100 to
check if there is a firewall.

Below is the web page that I get


Unable to connect

Firefox can’t establish a connection to the server at 192.168.1.100.

    The site could be temporarily unavailable or too busy. Try again in a
few moments.
    If you are unable to load any pages, check your computer’s network
connection.
    If your computer or network is protected by a firewall or proxy, make
sure that Firefox is permitted to access the Web.

Any ideas?
