What about eno2, you also have two IP addresses there and even in the same subnet, is this wanted or not? Can the second address of eno2 be found in the ifcfg file? Both eno2 and eno4 have "scope global secondary dynamic"

I think it does so and

Dear Simon, every second IP-address is unwanted. We restarted? eno4: nmcli con down eno4; nmcli con up eno4 and the second address vanishes. Then after a few ours, the second ip address reappears. This is the config-file of eno2: # cat ifcfg-eno2 TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=none DEFROUTE=yes IPV4_FAILURE_FATAL=yes IPV6INIT=no IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes

I have a second server and gave it a WAN address and I can connect between them using their WAN addresses. That's what told me that my ip6tables weren't screwed up and that the problem lay elsewhere.

I have centos 6 running kvm. IPv4 works perfectly works. But I am having some problem with ipv6, looks like its bridge routing problem but stuck. here are my bridge detail: bridge name bridge id STP enabled interfaces br0 8000.000af75613f2 no eth1 vnet1 br4 8000.000af75613f0 no eth0 ip -6 route shows : unreachable ::/96 dev lo metric 1024 error -101 mtu 65536 advmss 65476 hoplimit 4294967295

I've made 3 CentOS 7 installation attempts to configure a 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

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 A few months back, I tried to use the network scripts to provision an IPv6 range like can be done with IPv4. I was using CentOS 5.2 at the time and was informed that 5.2 was broken in this regard. I have upgraded to CentOS 5.3 now and I am trying to get IPv6 to provision an entire range of IPs, but I am still getting the old behavior and no IPs are
