Where is net.inet.ip.fastforwarding tune-able in pfSense 2.3?


  • I'm getting slow OpenVPN performance (3mbps over a 60mbps connection). In the previous versions of pfSense I would set net.inet.ip.fastforwarding=1 and that would usually correct the issue right away but I can't seem to find the option in pfSense 2.3.

    Anyone know where the option is or how to tune up my OpenVPN speeds?

  • So assuming that net.inet.ip.fastforwarding is not causing my performance problems, is there a good OpenVPN performance tuning guide you would recommend?

    Could it perhaps be that this might be a result of a negotiation issue betwen the LAN ports of the modem
    and the pfsense firewall? This would be more coming near to those problems often.

    If encryption comes in the game often lower end or very old hardware is not really so nice
    to play with it. Would you tell us oerhaps at first something about your hardware setup?
    Board, CPU, RAM, 32Bit or 64Bit, etc…...

    performance tuning guide you would recommend?

    Go with pfSense 2.3 64Bit and A CPU that comes together with AES-NI.
    Dual or Quad core CPU at around ~2,0GHz would be nice too and the fastest RAM you would be able to install.

    Do you know how to disable encryption on OpenVPN? I tried:

    auth none
    cipher none

    But then OpenVPN fails to start with "tls-auth enabled" something or other.

    I'm not really sure how many cores pfSense has access to:

    VPN implies encryption. To lessen the load you can choose AES-128 rather than AES-192 or AES-256, but you cannot disable encryption completely.
