Block Port Functionality
Is there any way to add a feature to block specific ports at the firewall across all devices? There is nothing that tells me what “Add a firewall rule”’under “Reservations & Port Forwarding” does.
I ask the question in light of the Cable Haunt vulnerability (https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-19494; https://nvd.nist.gov/vuln/detail/CVE-2019-19494).
When I called customer support yesterday, the representative said that there is no way to block ports.
Until ISPs push out the modem patch, users need to block port 8080 traffic at the router firewall.
I refer to Steve Gibson’s Security Now podcast episode #749 for January 14, 2020 (episode homepage -https://twit.tv/shows/security-now/episodes/749?autostart=false; show notes - https://www.grc.com/sn/sn-749-notes.pdf) Steve talks about blocking port 8080 on the router firewall as a mitigation until the modem is patched.
I also called Leo Laporte on The Tech Guy show about the ability of sophisticated users being unable to managed details of the Eero routers (https://techguylabs.com/episodes/1658/my-new-router-safe-online; https://techguylabs.com/episodes/1661/has-my-cable-router-been-hacked)
Wow 2 years later. Well for whatever my 2 cents is worth, a basic port blocking firewall would be nice. I never knew routers/mesh network devices didn't have that until I installed the Eero. There appears to be ipv6 firewall rules but requires to reserve an IP and designate an IP. That's not how to block ports that's how to forward them.
