I've tried:
+
Goodmorning,
−
net.ipv4.conf.all.arp_filter=0
+
 
−
net.ipv4.conf.all.arp_ignore=1
+
I have a similar problem.
−
net.ipv4.conf.all.arp_announce=2
+
 
−
net.ipv4.conf.default.rp_filter=2
+
I have following architecture:
−
net.ipv4.conf.all.rp_filter=2
+
2 PC (PC A and PC B).
−
and it seems to work for me. Daryl Radivojevic
+
PC A has 2 Ethernet interfaces (A_eth0 and A_eth1).
 +
PC B has 2 Ethernet interfaces (B_eth0 and B_eth1).
 +
 
 +
A_eth0 is connected through a wire with B_eth0 (in the middle there is a Switch: SWT_0)
 +
A_eth1 is connected through a wire with B_eth1 (in the middle there is a Switch: SWT_1)
 +
 
 +
IP addresses used:
 +
A_eth0: 192.168.30.1
 +
A_eth1: 192.168.30.2
 +
B_eth0: 192.168.30.3
 +
B_eth1: 192.168.30.4
 +
 
 +
netmask: 255.255.255.0
 +
 
 +
SWT_0 and SWT_1 are 2 different switch (in order to realize a physical separation).
 +
 
 +
Operating system on both machine: LINUX UBUNTU 9.04
 +
 
 +
Aim of my test:
 +
- realize communication between A_eth0 and B_eth0
 +
- realize communication between A_eth1 and B_eth1
 +
- A_eth0 and B_eth1 HAVEN'T TO communicate
 +
- A_eth1 and B_eth0 HAVEN'T TO communicate
 +
Problem I have:
 +
- IF I remove wire connection between A_eth0 and B_eth0 THEN B_eth0 is achieved by PC A (passing through the wrong interface B_eth1)
 +
In this case a non-desired communication between A_eth0 and B_eth1 is established.
 +
- IF I remove wire connection between A_eth1 and B_eth1 THEN B_eth1 is achieved by PC A (passing through the wrong interface B_eth0)
 +
In this case a non-desired communication between A_eth1 and B_eth0 is established.
 +
 
 +
I have realized following steps on both machines:
 +
sysctl -w net.ipv4.conf.all.arp_filter=1
 +
sysctl -w net.ipv4.conf.all.arp_announce=2
 +
sysctl -w net.ipv4.conf.all.arp_ignore=1
 +
 
 +
/etc/init.d/networking restart
 +
 
 +
or
 +
sysctl -w net.ipv4.conf.all.arp_filter=0
 +
sysctl -w net.ipv4.conf.all.arp_announce=2
 +
sysctl -w net.ipv4.conf.all.arp_ignore=1
 +
 
 +
/etc/init.d/networking restart
 +
 
 +
In any cases the problem is not solved.
 +
 
 +
Thanks for your attention.
 +
Regards
 +
Paolo
