This is the error that i’m getting when trying to ping google, in some reason i can’t ssh too checked the ufw and firewalld everything seemed on the right order but still can’t ping… I’m using Fedora 34 it’s a fresh install since i had a break after upgrading from Fedora 33 to Fedora 34… i’m not using VPN right now but i also noticed that i can’t seem to access certain ip address on my browser and no torrent file can be downloaded with the use of Transmission. please help, i’ve been checking system logs and ip tables but can’t seem to figure it out… another fresh installation of Fedora 34 is not an option.

I would start by doing a traceroute to see where your packets are dropping. If they aren’t going anywhere at all we would need to see your firewall rules.

Uhh…you are using both firewalld and ufw?

Hi,

Are you able to ping other devices on your lan, including your router?

Are you using firewalld and ufw on the same PC? If so disable one of them.

Thanks Tom.

traceroute to router, to raspberry pi4 to other servers on my rack and offsite server is not showing anything besides ***…

not sure what to check on firewall rules…

disabled ufw then tried to ping still has the same error and vice versa

5

yeah ping to other devices shows the same 100% packet loss… turned off the firewalld and ping still the same 100% packet loss and vice versa…

6

tried to disable both ufw and firewalld then ping google and other devices to check still get the same 100% packet loss

tried to

$ curl google.com

and it shows this…

Hi,

Have you stopped the firewall aswell as disabled:

systemctl stop ufu 
systemctl stop firewalld

Thanks Tom.

yeah, still 100% packet loss

11

Why do you think your firewall’s the trouble?

Check the output:

sudo iptables-save; sudo ip6tables-save; sudo nft list ruleset

Hi,

Have you tried restarting the PC, since disabling the FWs?

Thanks Tom.

I’m going to have a guess that it could be a DNS issue - the pages you can seem to reach may be cached and that could be why you can reach some pages but not others. Can you try to ping google using ip address 8.8.8.8 instead of the domain name. If 8.8.8.8 works then its likely a DNS issue.
I’d also look at ip route show and see what routes have been setup.

As an aside, I would usually setup iptables policies to drop all packets unless there is a specific rule to allow traffic…

Good luck! Cheers

Hi sorry for late reply, yeah i’ve done that still the same

yeah couple of time still the same issue 100% packet loss

still the issue persist

$ ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.

for the ip route… not sure what to look for but here’s the output
