Packet change and redirect using ebtables
Hey all
I need your help with ebtables. I want to redirect traffic through local interfaces.
I have am Ubuntu linux machine with several NICs.
(I understand that ebtables is the same for RH)...
eth0 and eth1 are part of a bridge (br0) and they are connected to tap device. On eth0 I get traffic from network 10.10.10.0/24 to the internet.
Through eth1 I get the responses, internet addresses to 10.10.10.0/24.
None of the packets are destined to the linux host (on L3 and L2 as well).
My goal is to separate the traffic to other interfaces.
Every packet that enters eth0 with source ip 10.10.10.0/24 should be routed or redirected to eth3 (Packet should have the same source and destination IP but the frame should now contain a new SRC MAC, eth3's MAC).
The same applies to traffic that is coming in from eth1. I want to route it to eth4.
eth0 and eth1 are unidirectional, that means that I can't change the traffic and I'm only intercepting it.
Can you please help me build this filter using ebtables ?
I had no luck so far.
Thanks !!

aoe-interfaces

aoe-interfaces(8)					      System Manager's Manual						 aoe-interfaces(8)

NAME

       aoe-interfaces - restrict aoe driver to specified network interfaces

SYNOPSIS

       aoe-interfaces [dev1] [dev2 ...]
       aoe-interfaces -c

DESCRIPTION

       The  aoe-interfaces command tells the aoe driver to ignore ATA over Ethernet (AoE) traffic on all but the specified network interfaces.	It
       is analogous to the aoe_iflist module load option.

       If neither the aoe_iflist module load option nor the aoe-interfaces command are used, the aoe driver will use any network interface for AoE
       traffic.   Using  aoe-interfaces  to limit AoE to only trusted networks prevents the case where a rogue AoE target appears on a public net-
       work, diverting data from the legitimate AoE target.  Such an imposter target effectively corrupts the data on the legitimate target.

       If the aoe driver is a module, then calling aoe-interfaces without arguments will display the current interfaces list.  If it  hasn't  been
       set then the output will be blank.

       It's good to run the aoe-discover command after setting the AoE interfaces list.

OPTIONS

       -c     The -c flag will clear the interface access list, permitting any interface to be used.

EXAMPLE

       In  this  example, the root user on a host named nai loads the aoe module with only eth0 allowable for AoE traffic.  After remembering that
       shelf 7 is on eth3, this sysadmin uses aoe-interfaces to add eth3 to the list of allowable network interfaces and then  calls  aoe-discover
       to ask the aoe driver to look for new AoE devices.

	      nai:~# modprobe aoe aoe_iflist="eth0"
	      nai:~# aoe-stat
		 e10.9		  eth0		    up
	      nai:~# aoe-interfaces eth0 eth3
	      nai:~# aoe-discover
	      nai:~# aoe-stat
		  e7.0		  eth3		    up
		  e7.1		  eth3		    up
		  e7.2		  eth3		    up
		  e7.3		  eth3		    up
		  e7.4		  eth3		    up
		  e7.5		  eth3		    up
		  e7.6		  eth3		    up
		  e7.7		  eth3		    up
		  e7.8		  eth3		    up
		  e7.9		  eth3		    up
		 e10.9		  eth0		    up
	      nai:~# aoe-interfaces
	      eth0 eth3
