Any considerations regarding settings when multiple ssids are configured ?

[Snailkhan]

Hi,
I have configured multiple ssids on my atom box.

are there any considerations regarding settings when multiple ssids are configured ? eg. frequency / channel ? authentication types ?

any performance degradation as a result of configuring multipe ssids ? (since shared medium, so should be there in my opinion . but how ? just need to understand it)

any good read specific to pfsesne.

One thing I know for sure is you can only use the same band, ie. 2.4ghz or 5ghz on your clones. cmb said earlier that they all must be on the same frequency/channel as well. I thought I had set it up with different frequencies for each, but I was probably wrong. Try it out, you can't do wrong.

When you dig deep into the FreeBSD wireless system you will see software access points are created as VAP or virtual access point. So adding multiple SSID does OK system wise. Not sure where the upper limit of connections are.

You will see a speed hit for encryption of any type.

Are you trying to do both client and master mode wireless setup? Or multiple Access Points?

In my test I ran 3 separate pfSense Access Points. One a regular WPA2 one, One Captive Portal, One Guest AP.

All three were "Routed Network" approach versus the bridged version seen in the above mailing list.

So make your AP and clones and assign them to interfaces, enable them and setup as static ip with separate address for each interface.

Then you must enable DHCP server for each interface and set firewall up for the OPT ports to allow traffic.

My question for the guru's would be: Is each VAP using a separate instance of hostapd? Or one instance with 3 configs.
