$ uname -a
Linux labsm 3.10.0-693.21.1.el7.x86_64 #1 SMP Wed Mar 7 19:03:37 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
EDIT
My initial problem was that local network is Ok, but internet was not accessible. It appeared that my machine was blocked by mac-address. Now I get my mac-address in the list of the ones allowed internet access and everything is working.
However, I have one more question about the network. The IP address in ifconfig doesn't match the one in the network-script.
I did disable the NetworkManager and configure the network-script, so that the machine has the IP address 133.21.224.237.
The network-script is:
{enp96s0f1}
$vi /etc/sysconfig/network-scripts/ifcfg-Wired_connection_1
HWADDR=0C:C4:7A:F9:BA:CF
MACADDR=0C:C4:7A:F9:BA:CF

IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=enp96s0f1
UUID=ef4dba55-7c9a-3d8e-94b6-5e2146284e1a

AUTOCONNECT_PRIORITY=-999
IPADDR=133.21.224.237
PREFIX=24
GATEWAY=133.21.224.94
DNS1=10.20.0.55
DNS2=10.20.0.56
PEERDNS=no
I did restart the network service with
$ systemctl restart network
But! In the ifconfig:
enp96s0f1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 133.21.224.29 netmask 255.255.255.0 broadcast 133.21.224.255

TX packets 56064 bytes 6389505 (6.0 MiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
So, the line inet 133.21.224.29 says that the ip address ends with 29, while I configured it 237 in the network-script. Even more interestingly, the machine can be accessed inside the local network by ssh with both IP addresses...
That IP address 133.21.224.29 was assigned to that machine some time before. But I don't understand how the machine receives it now, after I changed the network-script. What am I missing?
