CentOS 6 and IPv6 neighbor proxy
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...

Where to configure proxy NDP in startup scripts?
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

How To for IPV6
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...

Re: ipv6 NAT; accept_ra errors and about network choice
...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...

ipv6 NAT; accept_ra errors and about network choice
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
