Add new interface - loosing connection

  • Hello,

    i have following problem. My Setup:

    1 VM with pfSense 2.2.6:

    • Interface WAN = VMX0
    • Interface LAN1 = VM1
    • Interface LAN2 = VM2

    Now i want to add a additional Interface to this VM - Interface LAN 3 = VMX3. To add this Interface i must restart the VM and after that, pfsense is not available anymore. A Server that is in the same LAN 1 than pfsense can not ping the pfsense and pfsense can not ping the server.

    How can i add this interface without loosing the connection? It seems that the new interface confusing the other interfaces. When i delete the new interface and restart the vm, all is working again without a problem.

    Kind regards,
