    Google search shows lots of complaints on these guys. One of the services they supply are VPN's. If it was me, I would probably block in my router.

    It would not be prudent for FlexRadio to comment on other types of radio remote access.  I recommend if you have a question, ask them directly.

    We actually saw a number of different IP addresses show up in the reports that we saw.  They weren't all the same.  To prevent this kind of connection, you'll need to ensure that external connections (WAN) cannot access your radio.  To do this, make sure that you don't have any port forwarding to your radio and services like UPnP are disabled.  ***Just to be clear (for others), SmartLink will not function if you configure your network to refuse all WAN traffic to the radio.***

    Hi Tim, Thanks for the link to V4 of the Archer C8 manual.  I could not find sub chapter 10.4.  My version of the manual only goes to 10.3.  In the various security settings, I could not find a way to block a specific IP address from the WAN.  The only blocking tool I found was MAC address blocking.  I am running the latest version of C8 firmware.  Do you have any other suggestions?  Thanks, Geoff

    Hi Geoff
    The link posted shows an updated manual that has chapter 10, subsection 4.  If trhe router firmware does not support blocking the attack your seeing, I would personally replace it.  Using a Netgear commercial router here at the WAN interface and it seems very secure. 

    Perhaps a port scan to see what ports are open?
    Someone in IT security here on the community may have a suggestion...
