Socket Filter on a NIC?
Hi Guys,
I am trying to find out if the Kernel does/can put a filter on a NIC?
The thread i am trying to follow, is that i have a small theory that the filter may only allow packets who's Destination MAC match the MAC of the NIC they are trying to cross.
Thanks,
Rich.

If this didn't answer your question, please expand upon what you're trying to figure out
Yes i am aware that the Linux Kernel can filter packets based on MAC. I have seen that ipatbles is capable of doing this via Source MAC.
I have just ventured through many pages
What i am trying to do is quite difficult, and im still learning Linux
Instead of re-writing everything, i will post a link instead ----> http://www.linux.com/community/forums?func=view&catid=28&id=9847
Thanks.
I found that the ones labelled as redirect refer to ICMP (ping) and would not effect my TCP packets, is this correct?
Is it also correct that the ones that would affect routing of my packets are: rp_filter, arp_filter, arp_ignore, proxy_arp, accept_source_route, forwarding?
FYI - I coloured everything Yellow that has a value other than Zero.
Yes what you listed above will effect the routing of your packets.
