I have searched for this on google, but could not find any help.
I seem to notice this issue on new Centos 8.2 installations.
Older installations originally installed on Centos 8.1 and upgraded to 8.2 do not seem to have this.
I think this is the case.
The command
iptables -L -n -v
normally should show the dropped packets, but the counter stays at 0 for new Centos 8.2 installations.
If your INPUT policy is DROP, that counter should go up if it drops packets, but it does not on new installations.
example on an originally centos 8.2 installation:
Code: Select all
[root@server ~]# iptables -L -n -v
Chain INPUT (policy DROP 0 packets, 0 bytes)
Code: Select all
[root@server ~]# iptables -L -n -v
Chain INPUT (policy DROP 39 packets, 1748 bytes)
