    Hello,

    I have setup 2 VLANs between 2 mikrotik routers (1 for WAN and 1 for LAN) that communicates with each other through VLAN10. I put PfSense between these two routers. Now routers cannot communicate with each other and Pfsense acts as an Gateway. I want WAN router VLAN communicates with LAN router VLAN through Pfsense so I can filter their traffic.

    Can you help ? Any suggestions or guidance appreciated.

    Regards,

      Why would you put WAN and LAN on the same VLAN?

        Dear Derelict,

        I have posted the Figure of my existing network and new network below. I provide internet connection to LAN through this VLAN (VLAN10) since this VLAN has configured for specific routes and queue targeting WAN-LAN connection and other networks. (PFSENSE.png image url)

        All I want is to prevent users accessing to some websites in my network without modifying any configuration of my Mikrotik Routers and VLANs.
        The Pfsense will sit between 2 routers but it should allow VLAN10 to communicate between 2 mikrotik routers so it will trace network activities and block specific connection requests (e.g. facebook, youtube, xxx sites etc..) between WAN and LAN network.

          Nonsensical. Sorry.

          What is your purpose.

          What are you trying to accomplish?

            I want to filter the traffic for the VLAN10. That's why I want to use Pfsense. But WAN and LAN communicates each other through VLAN10 so when Pfsense intercepts the network it disconnects LAN from the Internet.

              What do you mean filter? As a firewall or as a transparent filter?

                Yes, actually it will filter the incoming and outgoing traffic so LAN users will not be able to access Youtube, Facebook, or any other site that I will set as a rule.

                  Look up transparent bridging/filtering.
