Create WiFi hotspot isolated through pfSense from rest of LAN

[Agent24]

I want to try to set up this (see attached diagram)

All wired network is already set up. I just want to add the pfSense and wifi component.

I'm just not sure how to do it. I was told that pfSense was the best to use in this situation.

Can someone give me some advice on this?

Why do you even need the switch and 'linux-machine' there? Your AP could probably handle dhcp just fine for both networks.

But if you really want to do it that way (and you have more clients than in the picture or you want something special) you can do it easily by buying three ethernet cards to the pfsense box (or using vlans). Then you have wan,lan and opt interfaces and you just plug the ap to opt and then configure dhcp.

There are lots of guides on the forum, just start digging. Altough the procedure is so simple that you dont probably even need any guides if you have any previous experience with networking.

GL and keep posting if problems occur ;)

You could even buy a supported wireless NIC capable of operating as an AP to use as OPT1 and eliminate the separate AP - one less box to manage, one less power socket to provide etc!

Possible configuration

–-- Internet---ADSL modem---PfSense---switch---PC1 to PC3
                                                 |
                                                 |----(wireless link)----PC4

I've been running a similar configuration for over 15 months EXCEPT I bridge the wireless link and pfSense LAN so the wireless systems (laptops used by family members) can access local printers.

You should be able to get a suitable wireless NIC for a bit less that a separate AP. New prices in Australia: about $30 for the NIC, $40 and up for a wireless router/AP.

I managed to get my diagram setup working, however the security is backwards, Wifi clients can access LAN PCs but not the other way around
