Hi every one,
According to my understanding, if I implement entables on my Linux
system, a frame should be passed through ebtables modules. Then, if
ebtables modules find the destination mac address of the frame is the
local mac address, it will transfer the frame to layer-3, that is
iptables, right?
Now I want to do a test, which modifies the destination mac address of
a frame before sending it. Therefore, the frame will be forwarded to
another destination instead of the real destination, while its
destination ip address is still the real destination ip address. In
this case, when the frame arrive at pseudo destination machine, will
it be transfered to lay-3 of the system? If it is transfered to lqy-3
of the system, the system will find the destination ip address is not
local ip address. What will happen next? Drop the packet? or send an
arp request to find the real destination mac address and forward it?
Thanks,
Sumin
