Hetzner reported not allowed MAC addresses in subnet
We had email from Hetzner network team asking us not to use MAC addresses belonging to the Virtual Machines belonging to the subnet.
We configured Xen server host as a router using this guide.
After asking for additional details Hetzner support answered that normally, the network configuration of your hypervisor should only let packets exit the system with the MAC address of the real NIC.
But if you do not find the issue, you might try to block those outgoing packets using IPtables.
So our questions:
If anyone had this kind of problem with Hetzner or other provider.
How you solved it? Is blocking using iptables the only way?
Thank you
