I recently bought 2 Intel D2500CC motherboards so I could replace another one that broke down.
The D2500CC looked ideal as it doesn't need forced cooling and has 2 NICs.
I bought 2 because I need to be able to replace it if it breaks down.
On the LAN NIC I have 35 VLANs and on the WAN I have 5 VLANs
I had to use an old Celeron system before I had this Intel D2500CC running.
Getting the Intel D2500CC to run took a long time. Somehow the VLANs stopped working just before pfsense fully boots. I had a feeling it had to do something with hardware vlan tagging, but it took me a long time before I found the command to turn this off.
After I executed "ifconfig em0 -vlanhwtag" the vlans started working again.
Can we have an option in the webif to turn this off, just like checksum offloading?
I now have to resort to a cronjob to turn it off http://forum.pfsense.org/index.php/topic,48155.15.html
I would rather know more why this is happening, but this option is a good start.
I also switched to the 2.1 development edition in the hope it would solve the problem (before I found the solution). It would be nice to get it in there before the release.
