<![CDATA[Planning to Transition to pfSense]]>Hello everyone,

First time poster here and as the title says, I am looking to transition to pfSense as my router/firewall but would like to get a little info first. I have poked around and setup pfSense as a VM for a virtual network I am running but would like to put this into my own LAN and make the transition as seamless as possible.

My current setup is as follows:

Arris SURFboard SB8200 modem >
Netgear R7800 router w/ DD-WRT firmware (Kong) >
Netgear GS728TPv2 managed switch >
CentOS 7 server running KVM (this is where I would have pfSense running)

  • server has 2 onboard NICs and a 2-port PCIe NIC card
    Other devices connected to switch as well (Apple TV/etc)

I will most likely use the PCIe card for pfSense (1-port (A) for WAN and 1-port (B) for LAN), and turn the R7800 into a wireless AP. Would the following connections be correct?

modem > pfSense WAN port (A) <> pfSense LAN port (B) to switch, All other devices to switch (PCs/AP/etc)

If so, how would I setup the WAN port of pfSense (static or DHCP)? I assume static? I know I can get to the modem UI via 192.168.100.1, but would that mean I need to set the pfSense WAN on the same subnet (192.168.100.x)? Thanks in advance for any info you can provide.

I will most likely make the switch this weekend and update when complete. Thank you both for your time and info 😁

Thanks for the reply @chpalmer. Sounds easy enough. Connection wise, everything else sounds good? Again just trying to make the transition as easy/seamless as possible. Thanks again for your time and patience.

Connection wise, what you laid out makes sense. That's the way I would do it as well. As suggested, if WAN is setup with DHCP and assuming the modem does its job of handing out a DHCP WAN address, it should just work.
Good luck.

You will get a public IP address on your pfSense WAN and should still be able to access your modem at 192.168.100.1
