Hello,
I have a 2-CPU system with 16GB RAM and an 11 drive RAID-5 array with a hot spare. The system came with a single 100Mb NIC and two 1Gb NICs. My intention was to use the single 100Mb NIC as a management interface with all of the SAN/NAS traffic passing through the gigabit network cards. The network adapters are all on the same LAN segment with fixed IP addresses and separate DNS names.
My FreeNAS version is FreeNAS-8.0.4-RELEASE-p2-x64 (11367).
I brought the system up with the 100Mb NIC configured first. I then added one of the gigabit interfaces without a problem. Before integrating the second gigabit NIC, I installed it into my production environment and migrated data to the storage. At first, it seemed to work great until I noticed poor performance with many users attached. I configured the nightly system reports and found out that the inbound traffic to the NAS is passing through the gigabit NIC and the outbound traffic is returning via the 100Mb NIC. I did not aggregate the NICs together so I am surprised that this is happening. It looks like some kind of automatic load balancing on the FreeNAS system but there doesn't seem to be any options for modifying this behavior.
Here is the network portion of the nightly report so you can see what my system is doing. fxp0 is 100Mb and bge0 is 1Gb.
Network interface status:

lo0 16384 your-net localhost 6 - - 24 - -
Does anyone know how to force all of the data traffic through the gigabit interface? Do I have to get rid of the 100Mb interface?
The simple solution would be to disable the 100Mb interface but I like to make things difficult.
Any help would be appreciated.
