"Single-Port pfSense Setup: WAN + LAN over One Interface | Cisco Switch Integration Lab"
In this practical lab, we configure pfSense with only one physical RJ-45 port to handle both WAN (SIP IP) and LAN traffic on the same interface. You’ll learn how to set up a fully functional network with pfSense acting as both firewall and DHCP server, while a Cisco switch distributes IP addresses to connected devices.
🔧 What you’ll learn:
Configure pfSense with a single NIC (WAN + LAN bridge or alias setup)
Assign static SIP WAN IP
Enable LAN DHCP on the same port
Integrate with a Cisco switch
Verify IP distribution and internet access
Great for small office networks, home labs, and virtualized or embedded pfSense appliances.
