Imi permit un citat din

"Netfilter is merely a series of hooks in various points in a protocol
stack (at this stage, IPv4, IPv6 and DECnet). The (idealized)
IPv4 traversal diagram looks like the following:
A Packet Traversing the Netfilter System:
--->[1]--->[ROUTE]--->[3]--->[4]--->
| ^
| |
| [ROUTE]
v |
[2] [5]
| ^
| |
v |
On the left is where packets come in: having passed the simple sanity
checks (i.e., not truncated, IP checksum OK, not a
promiscuous receive), they are passed to the netfilter framework's
NF_IP_PRE_ROUTING [1] hook. "
Deci ar rezulta ca nu e valabil pt. modul promiscuous.
Pt. Boni: -m mac --mac-source xxxxxxxxx, vezi doc.
