No, I don't need ti used the MAC Address. And actually my
iptables filter work pretty well. But, with this,
the MAC address of the source host change for each connection
10.0.0.225
+--------+
| B |
+-----+ | | +-----+
| A +-----------[ebtables]----------| C |
+-----+ +--------+ +-----+
10.0.0.3 10.0.0.32
Rappel:
when C send not filtered packet to A, A see the C MAC address with IP
10.0.0.32. when B send filtered TCP/IP packet to A with IP address
10.0.0.32 A see the B MAC address. This work but it's not acceptable.
the A MAC-IP association table will change setup all the time.
