Hi Folks, After 3 days solid on this I am at the end of the line as to what I can take. I have a number of servers up and running OpenVZ on CentOS without any issues, I am trying out proxmox for the better veth support however I simply cannot get IPv6 to route outside of the vmbr device Is anyone able to add any suggestions, tips, help to this before I throw the towel in. The server has a public IP and the Containers are using a local private range 10.0.0.0/24 IPv4 connectivity is not a problem: auto vmbr0 iface vmbr0 inet static address 10.0.0.1 netmask 255.255.255.0 bridge_ports none bridge_stp off bridge_fd 0 post-up echo 1 > /proc/sys/net/ipv4/ip_forward post-up iptables -t nat -A POSTROUTING -s '10.0.0.0/24' -o eth0 -j MASQUERADE post-down iptables -t nat -D POSTROUTING -s '10.0.0.0/24' -o eth0 -j MASQUERADE The containers can connect to the outside world over IPv4 using a veth interface or even venet. ---- I have also set up a vmbr6 for ipv6 it has an IPv6 address, it can see the outside world over ipv6 The container has a veth device eth1 with an ipv6 address, it can ping the vmbr6 device on the host node but not beyond it. I have tried setting up the default routes on the container using the vmbr6, vmbr0 and the actual ipv6 gateway, none of this makes any difference at all. sysctl.conf net.ipv4.ip_forward = 1 net.ipv6.conf.all.forwarding = 1 net.ipv4.conf.default.proxy_arp = 1 net.ipv4.conf.all.rp_filter = 1 kernel.sysrq = 1 net.ipv4.conf.default.send_redirects = 1 net.ipv4.conf.all.send_redirects = 0 net.ipv6.conf.all.forwarding= 1 net.ipv6.conf.all.proxy_ndp = 1 So can anyone offer up any advice at all, and can anyone give an indication on when proxmox will implement full IPv6 support? I have noted a few errors regarding proxy_ndp and fprwarding for IPv6 during boot but it seems to load anyway, for good measure I have echo 1 > /proc/sys/net/ipv6/conf/default/forwarding echo 1 > /proc/sys/net/ipv6/conf/all/proxy_ndp in rc.local and sysctl -p returns no errors. cheers. Ant. P/S I posted this once but it never seemed to post sorry if it double posts.
