hi, all
nwfilter has many rules which depends on mac of vm, but i find the mac address inside vm
is different from mac outside of vm.
outside mac:
vnet0 Link encap:Ethernet HWaddr FE:54:00:71:15:7B ,
inside mac:
eth0 Link encap:Ethernet HWaddr 52:54:00:71:15:7B ,virtio
why?
i am afraid that nwfilter use the wrong one.
how nwfilter chooses mac? and what is the usage of vnet0's mac?
You can basically ignore the mac addr on the host vnetNNN devices.
They don't affect the traffic to/from the guest.
