WiFi security ??

After running “WiFi Inspector”, it came up with the following info, (picture).
Suggesting that my Huawei WiFi router has an open port to the internet ???
Your router is accessible from the Internet…

To configure Huawei wireless router:
From the Wi-Fi Inspector results screen, select Go to your router settings to open the administration page of your Huawei router.
Enter your router username and password, or contact the party who provided the router (e.g., your ISP).
Go to Advanced ▸ ACL ▸ Access Control Setup.

  • or -
    Go to Advanced ▸ Firewall.
    Set ACL to Disabled.
  • or -
    For other routers with remote access supported only via the Firewall configuration, select ACL, and ensure that each Service Type (HTTP, ACL…) in the list has Access Direction set to LAN (i.e. not WAN).
    Confirm your changes by selecting Submit and reboot your router if necessary.

Well, I’ve logged into the Router, via 192.168.1.1 and used my logon & password, (OK)…
however, I can see NO ref anywhere, under ANY settings, for …
‘ACL’, or anything like it ???

Am I missing something, as this ‘ACL’ setting is not available ???..

Avast is just the messenger here.

Suggest contacting Huawei or your ISP, whichever applies, and query how to fix this vulnerability through the firmware you have. If supplied by your ISP, request a newer non-vulnerable modem/router in exchange.
