    i've been getting lots of port scans and lfd's from dynamic-ip.hinet.net since day one.
    CSF seems to be doing it's job, but is there anything that can be put in place (other than blocking the whole of TW), that will just kill it dead, rather than csf having to work it out.
    I'm pretty sure i asked before but don't recall the outcome.

    Tomorrow it will be China. Next week, Russia. The week after that, pick one.

    You can Block whole countries in CSF if you like, but the IPs can come from other countries that you don't block. You asked previously, How do they find you, port scans is one of the many ways.

    yeh, i know how they can come from anywhere, and with any frequency.
    I'm seeing a few from Brazil today.
    This one however, seems to be trying email logins too, and after googling it, seems is quite a common domain.
    In the short term, i added to csf

    1.160.0.0/16 #do not delete
    36.0.0.0/8 #do not delete
    118.0.0.0/8 #do not delete
    114.0.0.0/8 #do not delete
    111.0.0.0/8 #do not delete

    hopefully this will slow them down a little.
    Time will tell.
