Yes, br0 contains main server`s IPv4. So I perform tuning and now my IPv6 address pingable - but from this node only (and not on CTs on this node). This node CTs or other internet places - they do not see my IPv6. Other 2 secondary IPv6 addresses not even pingable from node.
My steps: # nano -w /etc/sysconfig/network-scripts/ifcfg-br0 IPV6INIT=yes IPV6_AUTOCONF=no IPV6_DEFROUTE=yes IPV6_FAILURE_FATAL=no IPV6ADDR=myIPv6IP_1 IPV6ADDR_SECONDARIES=myIPv6IP_2 myIPv6IP_3 IPV6_DEFAULTGW=myIPv6GW # nano -w /etc/sysconfig/network NETWORKING_IPV6=yes IPV6FORWARDING=yes IPV6_DEFAULTDEV=br0 IPV6_DEFAULTGW=myIPv6GW IPV6_AUTOCONF=no # echo "net.ipv6.conf.default.forwarding = 1" >> /etc/sysctl.conf # echo "net.ipv6.conf.all.forwarding = 1" >> /etc/sysctl.conf # echo "net.ipv6.conf.all.proxy_ndp = 1" >> /etc/sysctl.conf # sysctl -p # nano -w /etc/sysconfig/iptables-config IP6TABLES_MODULES="ip6_tables ip6table_filter ip6table_mangle ip6t_REJECT nf_conntrack_ipv6" # reboot -n чт, 15 груд. 2022 р. о 14:34 Arjit Chaudhary <arji...@gmail.com> пише: > Hi, > It could be in br0 if you are bridging enp3s0f0 and/or enp3s0f1 > > Basically the interface which lists as UP and with the IPv4 information > etc should be the right one in my experience. > > But do back-up original configuration files on the system, before editing > just incase something goes wrong you can just copy them back and restart > networking. > > > On Thu, 15 Dec, 2022, 17:40 Oleksiy Tkachenko, <meale...@gmail.com> wrote: > >> I have many) >> # ip a >> 1: lo: >> 2: enp3s0f0: >> 3: enp3s0f1: >> 4: enp0s20f0u9u2c2: >> 5: br0: >> 6: virbr0: >> 7: virbr0-nic: >> 8: venet0: >> 9: host-routed: >> 11: veth72240bcc@if3: >> 12: veth720bed05@if3: >> 13: veth7290a381@if3: >> 16: veth721813e6@if3: >> 17: veth720a338a@if3: >> 24: veth729a3460@if3: >> 25: veth720c6518@if3: >> 26: veth721bbb55@if3: >> 27: veth72705632@if3: >> 28: veth72b28dcd@if3: >> >> >> чт, 15 груд. 2022 р. о 13:52 Arjit Chaudhary <arji...@gmail.com> пише: >> >>> Is your interface name different by chance? >>> >>> Can you check, >>> >>> > ip a >>> >>> for the actual interface name and then update that interface >>> configuration for the IPv6. >>> >>> On Thu, 15 Dec, 2022, 16:43 Oleksiy Tkachenko, <meale...@gmail.com> >>> wrote: >>> >>>> Thank you! >>>> During node preparation I need to update >>>> "/etc/sysconfig/network-scripts/ifcfg-ethX" - but there is no such file. >>>> I also need to put "eth0" in "/etc/sysconfig/network" file - is it >>>> actual now (when I have no ethX file)? >>>> >>>> I also need to "Add 'ipt_state' to IPTABLES and 'nf_conntrack_ipv6' to >>>> IP6TABLES" in "/etc/vz.conf" - there is no such file also. >>>> I have "/etc/vz/vz.conf" on my bare metal openvz7 but there is no >>>> "IPTABLES" or "IP6TABLES" mention at all. >>>> >>>> >>>> чт, 15 груд. 2022 р. о 02:03 Arjit Chaudhary <arji...@gmail.com> пише: >>>> >>>>> (In my experience) >>>>> >>>>> Does the host-node have working IPv6 configured on it?
