I am having an odd issue with my Freenas server, It is setup as such:
Two network interfaces
EM0 - 192.168.0.8
EM1 - 192.168.0.9
I have an ESX box that connects to an iscsi target that ONLY runs on 192.168.0.8, it is disabled on 192.168.0.9.
I have samba setup on the box as well.
Now, I am copying files on a box to a samba share via 192.168.0.9.
Although looking at the interface graphs, It seems as though RX is being done by 192.168.0.9 and TX is being done by 192.168.0.8, I have attached the bandwidth graphs.
