Access pfSense firewall from WAN, inside LAN?



  • I have a small network with a Comcast cable modem bridged to pfSense, which is my gateway firewall/router. I am trying to troubleshoot a problem with a VPN that works when I connect to pfSense on my laptop from inside the LAN, but does NOT work properly when I connect to pfSense on my laptop from anywhere else on the WAN (public Internet). What I would like to do, if possible, is to connect to pfSense on my laptop from my LAN but somehow make pfSense think that I am connecting from the WAN. This would just be for troubleshooting purposes. Currently, to troubleshoot the problem, I have to leave the premises where the LAN is located in order to attempt to connect to pfSense from the WAN, which is incredibly inconvenient. Does anyone have any thoughts on how to do this?



  • You could use a VPN service provider. Then install their client on your laptop and set it to route all traffic over the VPN directly from your laptop to the VPN provider. Then when you try to connect the to pfSense VPN at your public WAN IP, the laptop should send all that inside the already existing tunnel up to the VPN service provider and it will then come back over the public internet to your WAN interface.



  • For troubleshooting purposes like this,
    i use another public IP from my modem, and use this with a laptop for trying to access via WAN.

    If i'm not at home and on location where no extra public IP is available,
    then i use my Android smartphone as a Wifi hotspot.
    Then i connect my laptop with this Wifi hotspot.

    +1 on the WiFi hotspot idea.  I just had to do that to test my WAN after the 2.2.3 upgrade.



  • I used the OpenVPN client on my Android phone to troubleshoot my own OpenVPN setup.

    #1 Disable WiFi on the phone
    #2 Fire up OpenVPN client and connect to my VPN
    #3 Do testing on the phone

    That was enough for me to figure out whether OpenVPN was configured properly on pfSense.

    (I'll have to try the Android phone as a WiFi hotspot idea as well.)
