      Hi. Sorry if this is a newbie question. I'm having issues with blocking internet for specific IPs.

      The topology: Modem > Router > Pfsense on Proxmox

      The setup:
      Proxmox network:
      eth0: port 0 on nic
      eth1: port 1 on nic
      vmbr0: connected to eth0
      vmbr1: connected to eth1

      pfsense vm:
      net0: vmbr0
      net1: vmbr1

      pfsense:
      wan: vtnet0
      lan: vtnet1

      router gateway: 192.168.20.1
      wan ip: 192.168.20.111
      lan ip: 192.168.1.1

      firewall rules:
      WAN:
      1)
      action: allow
      protocol: IPv4 ICMP
      source: *
      port: *
      dest: *
      port: *
      gateway: *
      queue: none
      schedule:
      Description: PING
      2)
      action: block
      protocol: IPv4 *
      source: 192.168.20.121 (a client)
      port: *
      dest: *
      port: *
      gateway: *
      queue: none
      schedule:
      (logging on)

      LAN:
      1)
      action: block
      protocol: IPv4 *
      source: 192.168.20.121
      port: *
      dest: *
      port: *
      gateway: *
      queue: none
      schedule:
      (logging on)

      Log:
      Action: Block
      Interface: WAN
      Rule: USER_RULE
      Source: 192.168.20.111
      Destination: 224.0.0.251:5353
      Protocol: UDP

      There are no entries in the log for any PASS or BLOCK for LAN. The firewall rule for 192.168.20.111 is the same in WAN and LAN for testing purposes.

      I think there's an issue with the LAN since there doesn't appear to be any traffic at all for LAN in the logs.

      What am I missing here?

        @zzoro said in Pfsense on Proxmox: No traffic on LAN / Only seeing 224.x.x.x traffic on WAN:

        pfsense is a router / fire wall.
        Why have you put it behind another router?
        The modem at the front, is that another router?

        While is possible to have a double NAT doing so complicates the system.
        Have you configured pfsense to blocked LAN addresses on your WAN? Doing so would block internet connection to pfsense given your topology.
