Problem with Interface Bridges

  • Hi everyone!
    Here is my situation:
    I have a DGS-1210-10P switch that have the following VLANs:

    vlan 10 –-> LAN
    vlan 20 ---> WAN

    I have my PC connected to the trunk port. Installed windows 10, Hyper-V and a pfSense VM with following setup:

    VM has 5 NICs:
    hn0 ----> internal with no vlan tagging
    hn1 ----> external with vlan identification 10
    hn2 ----> external with vlan identification 20
    hn3 ----> internal with vlan identification 99
    hn4 ----> internal with vlan identification 90 (just a place holder when creating bridge)

    I want to bridge hn0 and hn1 as LAN so my PC (vm host) can communicate easily with my rest of network.
    In my first attempts I lost connectivity to my pfsense box so I have installed another VM with windows 10 with internal interface on vlan 99.
    So I can configure the pfsense via a separate port.

    I have installed latest pfsense (pfSense-CE-2.4.2-RELEASE-amd64) with default options. I can connect to the WAN (PPPOE) and the host PC can ping internet and pfsense box just fine.
    The Interfaces are:
    LAN -----> hn0 with DHCP enabled and IP range of
    WAN ----> hn2 PPPOE connection
    OPT1 ---> hn1 I have just enabled the interface with IP configuration of none
    OPT2 --->hn4 I have just enabled the interface with IP configuration of none
    OPT3 ---> hn3 with DHCP enabled and IP range of

    After creating a * allow rule in firewall on OPT3 I can ping pfsense on windows 10 VM.
    So I connected to pfsense box via on my windows 10 VM and first I have toggled the values of and under System > Advanced on the System Tunables tab.

    I have restarted pfsense to make sure of settings effect.

    I have created a bridge with OPT1 and OPT2 as members.
    After that under interfaces I changed to the following:
    LAN ----> BRIDGE0
    WAN ---> no change
    OPT1 ---> no change
    OPT2 ---> hn0
    OPT3---> no change

    After hitting save I lost connectivity from the Host PC but still can connect from the windows 10 VM. I don't know what to do. Please help.

  • Is it my bad English or what?

  • If you help me in any way, it would be appreciated.

    In what scenario would you need/want to create a bridge on a vm?  Zero sense..
