Device with static IP can access network but cannot be accessed from another devices in the network

After solving Internet Interface is up but cannot access internet in the same device with Chapter 19. Managing the default gateway setting Red Hat Enterprise Linux 8 | Red Hat Customer Portal, now I get a novel problem, I can access the internet but cannot ssh or pinginto the machine. Ping giving message: Host out of reach

Please do not tell, post the whole commandline and the output.

Last attempt is giving this:

PING ( 56(84) Bytes an Daten.

White space is not an error

From where do you ping?

From a Linux Laptop connected by wifi to the same network/modem.

Check that the router is not configured to isolate wifi and wired LANs or similar.

I called to my internet provider and says it cannot do it.

Do you not have administrative access to your gateway router?

I don’t know a lot of networking.

Well, typically you can access your home router via a web interface using it’s gateway IP. If you search for the model online, you can usually find a guide to help you with this.

BTW, show us the output of the following commands

ip address
ip route

From where I have to run it?

You run commands like this from a terminal (eg konsole if using KDE, gnome-terminal or xterm if using Gnome).

I mean from the server of from my laptop?

From your laptop. Isn’t that the host having a problem with LAN connectivity?

ip address
2: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether a8:93:4a:3b:86:2d brd ff:ff:ff:ff:ff:ff
    altname wlo1
    altname wlp1s0
    inet brd scope global dynamic noprefixroute wlan0
       valid_lft 68480sec preferred_lft 68480sec
ip route
default via dev wlan0 proto dhcp src metric 600 dev wlan0 proto kernel scope link src metric 600

Ok, so the gateway IP address is (not as you previously attempted to ping). Are you trying to reach your server from the laptop?

If so, assuming it is a Linux server, find its IP address from a terminal on the server itself using

ip address

I have not tried to ping the gateway, but my server, which I give as an static ip. (Just confirmed with ip a)

What about the reverse direction? Try to ping the laptop from the server.

If that fails, we may need to access the gateway router (at

Something like this

PING ( 56(84) bytes of data.
64 bytes from icmp_seq=1 ttl=58 time=6.07 ms
64 bytes from icmp_seq=2 ttl=58 time=5.77 ms

from a ping, because is not easy to get some text form the server, but if needed…
