To route a subnet in ipv6 there are two possibilities: - add route commands for the subnet in each computer - or use neighbor proxy in the router server I prefer neighbor proxy. So I have to activate neighbor proxy in the router: sysctl -w net.ipv6.conf.all.proxy_ndp=1 and I have to add entries for each client in the subnet like ip -6 neigh add proxy 2001:0:0:1:211:d8ff:fe97:3273 dev eth0 This works well but is lost on reboot. For the sysctl command there is /etc/sysctl.conf for permanent configuration. If I create a file route-eth0 in the directory /e...

Hi! For my network setup I need the following commands: sysctl -w net.ipv6.conf.all.proxy_ndp=1 ip -6 neigh add proxy 1234:5678:9abc:def0::2 dev eth2 The first command goes to /etc/sysctl.conf to enable it after a reboot. But where do I put the "ip -6 neigh add proxy"? Best regards Franz

Hi, I try to set up - A centos 6 firewall - With proxy-arp (I know: arp is not supported in ipv6) with ipv6. Arp does not exist for ipv6. So I have added: sysctl -w net.ipv6.conf.default.proxy_ndp=1 To use the neighbor proxy facility. How to activate ipv6 forwarding? As far as I have found, this changed in RHEL6 from 6.1 (/etc/sysconfig/network) to 6.2 (/etc/sysctl.conf). CentOS 6? So I have used sysctl -w net.ipv6.conf.all.forwarding=1 as in RHEL 6.2 As in ipv4 I would p...

...at would be ideal. I don't think NAT with IPv6 is a wise thing to do, but my ISP just delegates a /64 prefix to me. So I need NDP proxying because my guests need to appear on the same network. I do it manually with something like: echo 1 > /proc/sys/net/ipv6/conf/<upstream interface>/proxy_ndp ip -6 neigh add proxy <guest address> dev <upstream interface> and passing my network prefix to libvirt: <ip family='ipv6' address='<my prefix>::1' prefix='64'> </ip> works flawlessly, dnsmasq gets configured properly on the host and the...

Hello, Firstly THANK YOU for the IPv6 NAT support merged in 6.5. It has been almost impossible to get IPv6 into a VM on a laptop that switches between wifi and wired (dock) connections, because you can not add a wifi interface to a bridge. I know NAT is against the IPv6 end-to-end xen but it makes this "just work" for the vast majority of people like me who need to ssh/curl/talk to
