Basic network configuration / preparation for pfSense

[cs1212]

Hi all, I am looking for a pointer of how to change my internal configuration to prepare for pfSense.

internally I have a linksys router on which I run DHCP. it is connected to my cable modem. I will install pfSense between the router and the cable modem.

currently my linksys router has IP 192.168.0.1 and also is running DHCP server.
should I set up pfSense to be 192.168.1.199 for example and then make it the DHCP server ?
should the linksys-managed LAN be on the same subnet as pfSense?

thank you for all your pointers.

• Settle on LAN subnet that's not 192.168.0.0/24 or 192.168.1.0/24.

• Replace the Linksys with PFsense, assign the first available IP in your new range to the LAN interface and enable DHCP

• Assuming you want to reuse the Linksys for wireless, give the Linksys a static IP in your new LAN subnet that's outside of your new DHCP range, disable the DHCP server on the Linksys, attach the Linksys to your switch via the LAN port on your Linksys (Not the WAN port)

That is a basic setup and will look like this:

Modem -> PFsense -> Switch -> LAN
                                      |
                                      |–---> Linksys -> Wireless

Anything more complicated will involve managed switches, VLANs and/or extra NICs.
