      Hi Guys,

      Not sure if this should be in the virtualisation area as im using vmware, I dont think my problem is vmware related though..

      I have my WAN interface plugged directly into a cable modem and cloned the mac address of the physical NIC, this works fine and gets a IP assigned by the ISP.

      I then have the LAN interface (192.168.0.0/24) which is wired into a switch, PCs connected to the switch obtain an IP from pfSense and can browse the web.

      My problem lies with the OPT1 interface (172.16.0.0/16), this is a wireless interface, when PCs connect to wireless they still obtain an IP and can ping the default gateway (pfsense) however they are unable to browse.

      Should OPT1 be getting nated as norm like the LAN interface? Or is there something else I need to configure?

      I cant see any hits in the firewall log that would point to a rule problem.

      Any help would be greatly appreciated.

        are you using windows VMware?
        this is a VMware limitation.
        you cannot bridge WLAN.
        with linux it's possible afaik.

        google for "bridge" "WLAN" and "VMware".

        We do what we must, because we can.

            Just a quick update, the problem is not limited to OPT interfaces, I have reassigned the bridged WLAN to the LAN interface and still have the same problem..I have found a temporary solution though!

            I have installed the squid package :) now if I configure the proxy in the wireless PCs browsers they are able to browse fine :)

            This is only temporary though as it is only useful for applications that support proxies..

            Does anyone have any ideas on this? The wireless PCs are even able to resolve DNS, pinging various websites resolves the IP put simply times out..

              you just cannot bridge a WLAN interface to anything in a Virtual Machine under Windows with VmWare.
              it doesnt matter if it's an OPT or the LAN or WAN. it wont work –> limitation of vmware.

              what does work: you can NAT your interface from inside the VM to a real WLAN-card. (VMWare does the NAT) but then you can only access stuff from inside the VM, but you cannot acces from outside to the Pf.
              you can forward singe ports, but no ranges.

              We do what we must, because we can.

                    what is your solution?
                    because i tried to do almost the same setup as you described and started googleing.

                      I changed the NIC I was using for wireless in VMWare to a host only and created a MAC bridge on the host, bridging the host only VMNet with the Physical Wireless card.

                      Hope that makes sense..been up a while ;)

                      There is a reg edit needed to allow you to include a VMNet interface in a bridge, I can post it later if your interested..

                        wtf O_o
                        i tried the exact same thing but didnt get it to work.
                        i've read some stuff about you cannot bridge WLAN because multiple MAC's on the same device in a WLAN lead to discarded frames.

                        maybe i should try once more :)
                        did you find somewhere a howto?
                        i have the regedit-changes i need to do.
                        possible that i did something completly wrong >_>
