Pfsense as Firewall and router,dd-wrt router as AP need some help

[fobbie]

Hi Guys,

Im new to Pfsense and need some help.
The reason why I have to use a wireless router is because pfsense don't have pretty good support on wireless cards, tried a TP-link and a rosewill card, none worked.

Here is the problem,
my service provider is ATT uverse business, 4 static IPs
we have about 8 work station, 1 server, 1 DVR and a couple printers running off the modem/router att provides, wired and wirelessly. I guess its too much for it so we have to restart it every 3 days-5days or so.

I have already built a machine running Pfsense with 2xGB cards, 1 wan and 1 lan.  1x100m that is on the motherboard as OPT1 for my wireless router.

wan is directly to my att modem, lan is to a switch for all my working station,server,DVR and printers. worked perfect, using 192.168.1.1 and 255.255.255.0
my att modem/router is 192.168.1.254
for DD-wrt router, I really don't know how to config it.

There are 3 wireless working station which needs to connect to the server as well

Should I just use DHCP and AP mode on the router and everything will work?
Or should I provide a static ip like 192.168.2.5 which is different than my PFsense?

Please provide the best solution for this.

Thanks in advance.

You should have your DD-wrt box setup as an access point only so:
Disable DHCP on the dd-wrt box.
Enable DHCP on the pfSense OPT1 interface.
Set the dd-wrt box to a static IP in the OPT1 subnet so you can access it later.
Connect the ethernet cable from the pfSense OPT1 interface to one of the dd-wrt LAN ports.
Add firewall rules to the pfSense OPT1 interface to allow traffic from the wireless clients to your server.
