Pfsense 2.0 Cisco trunk Problem



  • Hi Guys,

    I have some Problem with Pfsense 2.0 and Trunking Port (Cisco 3560)

    VLAN2,VLAN3,VLAN4 –-> Trunking Port Cisco --->PFSENSE NIC with Vlan id's

    generally it works! but if a tcp connection comes from VLAN2 to VLAN3 get a sync, get stream and then connection timeout.. WHY?.. i had try to Monitor the Problem with wireshark many tcp retransmissons and then comes the timeout

    i've try it with 2 Different NIC's and same result

    my Cisco trunk settings are following

    show int fastEthernet 0/16 switchport
    Name: Fa0/16

    Anything in the firewall log when this happens?

    You could be getting some asymmetric routing going on.
