When I first setup the new server (the OS running on the hardware) I had a problem of IPv6 dropping out after a while which might be similar to the problem you mentioned in the past Andrew. It turned out that I hadn't copied the sysctl.conf entries to the new server with the following in particular. IPv4 forwarding isn't needed as the Hetzner routers send packets directly to the MAC of the VM based on ARP. But IPv6 does things differently. net.ipv4.ip_forward = 1 net.ipv6.conf.all.forwarding = 1 It seems that when a VM boots up it somehow tells the Hetzner routers where to send IPv6 packets for it, and then sometime later the routers forget that and use a static route for the /64 which sends it to the OS on the hardware. If IPv6 forwarding is disabled the hardware OS doesn't forward them to the VM. If IPv6 forwarding is enabled they get forwarded. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/ _______________________________________________ luv-main mailing list -- [email protected] To unsubscribe send an email to [email protected]
