24.1 Legacy Series / Configure OPNSense as a firewall router
« on: May 31, 2024, 10:16:27 am »
Hello together
I want to configure OPNSense as a firewall in my home network, but after I have activated OPNSense behind my internet modem which is configured as a bridge modus all my LAN connections were blocked by OPNSense, the Firewall Rule for my LAN is configuread as Direction in and Source and Destination as any, the WAN connection is configured with Direction in and Source and Destination as any.
Unfortunately i still don't understand where i made a mistake, please don't forget i am relatively new with opnsense and firewall setup, can you take a look at my network diagram and help me to find the error?
I have configured my home network as follows:
OPNSense was connected behind my Internet modem, the modem is configured with DHCP which is configured in bridge mode, and the OPNSense FW it also gets an IP from my Internet provider.
I have configured the LAN interface on OPNSense with the static IP address 192.168.2.2 and DHCP is deactivated.
The LAN IP address of the OPNSense FW was entered as WAN Connection on my Wifi router.
DHCP has been activated on the Wifi router with the DHCP IP range 192,168,1,0/24.
