Hi There is a Centos 7 up-to-date box with 2 interfaces, let's say 192.168.1.12 - enp2s0, 192.168.1.13 on enp3s0. Default gateway on enp2s0. The gateway is pfsense, IP is 192.168.1.1 with 2 WAN connections On the gateway the outgoing traffic is routed by source ip to different WAN, 192.168.1.12 to WAN1 and 192.168.1.13 to WAN2 On the centos box are set all the route and routing rul...

...simple firewall/router box with 2 nics. I got myself into a circular scenario where NetworkManager and firewalld and /etc/sysconfig/network-scrpts/ifcfg-***** were interfering or overwriting each other. Needed to perform ifdown enp3s7 on the internal LAN nic in order to make the external internet enp2s0 reach websites and ping nameservers. After completing firewall-cmd --complete-reload the internal LAN nic would still provide private ip addresses via dhcpd server but LAN clients could not access the internet. So far these steps work to enable both nics to provide router and firewall services:...

...int of view doesn't matter, the routing to different WAN is a job of gateway's. And as I said in the initial message I achieved this ... :) The question is how can I achieve this with more elegant way, because the "route" command is deprecated anyway. So, again: Centos 7 2 NICs enp2s0-192.168.1.12 enp3s0-192.168.1.13 default gateway on enp2s0 is 192.168.1.1, defined in /etc/sysconfig/network Which other way (preferred with "ip route") can I add this, but: #route add default gw 192.168.1.1 dev enp3s0 ???? Thanks Levi

...oad balancing. Even if both servers respond with *Offers* to the client, the client will select one and issue *one Request* to the selected server.

...dalert/a1687ae4da1cc44a437d> Ah ... Caught it. So here is the IPTABLES method to block output on port 22 from internal machines on a gateway: iptables -I FORWARD -p tcp --dport 22 -i {name-of-internal-interface} -j DROP So, for example, if your internal interface is, for example, /dev/enp2s0, you'd write iptables -I FORWARD -p tcp --dport 22 -i enp2s0 -j DROP If you want to log such attempts, preceed it with a log request. Since I'm using the -I command (insert at top), it means the log request is entered second: iptables -I FORWARD -p tcp --dport 22 -i {name-of-in...

Everyone, I have not been able to get ether-wake to work waking up other centos 7.6 machines after the upgrade to Centos 7.6. Has anyone else had this problem, and if so any luck with a fix? Greg Ennis

Machine is an internal server with zero need to provide or receive ip addresses using dhcp (all IPs are hard coded). Question: how do I disable dhcpv6-client on this box?

...sktop or workstation, I usually get rid of NetworkManager: # systemctl stop NetworkManager # yum remove NetworkManager Then I edit the /etc/sysconfig/network-scripts/ifcfg-XXXXX file corresponding to my network interface. Here's a working example: # /etc/sysconfig/network-scripts/ifcfg-enp2s0 DEVICE=enp2s0 TYPE=Ethernet ONBOOT=yes BOOTPROTO=dhcp Now I wonder how I should configure things on a laptop, where I usually keep NetworkManager.
