PFsense + 1 WIRELESS NIC broadcasting two SIDS for 2 VLANS?
Is it possible to configure pfsense with a wireless card so that it broadcasts two SIDS? So that I can serve two different VLANS?
You can do this in 2.0 with a supported Atheros-based card and can create up to four of them with the same card. It requires at least FreeBSD 8.0, but pfSense 1.2.3 is using FreeBSD 7.2.
Why specifically Atheros? If i do it outside pfsense what kind of hardware specifics am I looking for in a wireless NIC? and why maximum 4?
It is just the only driver that we know has it working. (driver is called ath) The limit of 4 is in the driver.
We do this quite often with pfSense and Engenius WAPs. Most of the Engenius equipment supports VLANs and up to 4 SSIDs. As long as the wireless resides outside the pfSense box 1.2.3 will work fine.
