PfSense hangs after NAT of Firewall changes



  • I have following network configuration:

    Hardware router:
                Wan - 10.10.234.34/24  ISP network (static ip NAT enabled)
                LAN  - 192.168.2.1/24  my home network

    In my home network there is a box with single network adapter connected to the router and VMWare server  installed.
    One of VMs is running pfSense it has 2 virtual network adapters, both briged to host machine  network adapter:
              WAN - 192.168.2.10/24
              LAN  -  192.168.1.1/24
    pfSense esteblishes PPTP over WAN (the ISP provides internet access in such manner)

    Two other VM, one phisical box and SIP adapter have IPs from  192.168.1.1/24 and gw 192.168.1.1

    Everything works fine unless I change anything in NAT or Firewall configuration. In 70% of cases such changes lead to pfSense hang and only way to bring it up is VM restart.

    Any ideas?



  • You shouldn't bridge both interfaces to the same interface, use a second interface for one of them. You should also run VMware tools and use vmxnet, the vlance doesn't work all that well.



  • I've done as you recommended.
    Now pfSense ethernet adapters are connected to two different physical ones.
    WAN - 10.10.234.24/24
    LAN - 192.168.1.1/24

    HW Router is used as switch (wan port is not used)

    vxnet and vmtools are installed

    pfSense still hangs after firewall setting changes…



  • I've localized the problem, it is in OpenVPN over PPTP. I created new  thread in OpenVPN forum
