Block incoming connections and ports - ZyXEL EMG2926-Q10A
Greetings,
On the Videotron modem ZyXEL EMG2926-Q10A, does anyone know how to block all incoming traffic (from the internet to the modem) and how to lock all ports from incoming connections?
When login into the modem via a web browser and the clicking on: Expert Mode > Configuration (left side of the screen) > Security > Firewall > Services > Add firewall rule , I cannot find the option for “incomming” traffic or “outgoing” traffic. There is only the “Source_IP_Address” which I suspect is the way to block the incomming connections to the modem. From my point of view, one would have to list all IP addresses as “source” by stating an IP address range such as 0.0.0.0 to 255.255.255.255.
1) Is that the way to block incoming connections to the router?
2) What is the correct way to type/state an IP address range in the EMG2926-Q10A?
Regarding blocking the ports on the modem from incoming connections:
3) is that within: Expert Mode > Configuration > Security > Firewall > Services > Add firewall rule > SourcePortRange that ports 0 to 65535 have to be typed in to prevent people outside the network from scanning/using ports on the modem?
Lastly, its not clear if creating a firewall rule (as stated above; “Add a firewall rule”) will create a rule that “allows” or “block” the traffic.
4) Does firewall rules block or allow traffic?
Thanks in advance,
Regards,
B

I'm also wondering if you have an open port accessible 8159 from the outside, to confirm if it's the default configuration as well
Hello,
You normally do not need to block every IP range manually (0.0.0.0–255.255.255.255). Instead, look for a firewall rule option such as WAN → LAN direction and set the action to Deny/Reject for unwanted inbound traffic. If the firmware does not expose direction settings, the router may already handle inbound blocking automatically.
Best RegardsI believe most routers already block unsolicited inbound traffic by default unless you've enabled port forwarding or specific services. It may also help to compare your firewall settings with resources covering Leon Property Search to see how different systems organize network and configuration details. Hopefully someone familiar with this ZyXEL model can confirm the exact rule behavior, since the interface can definitely be confusing. Thanks for raising these questions—they're useful for anyone trying to improve network security.
Thanks for sharing this guide. Managing incoming connections properly is an important step for improving network security and reducing unnecessary access attempts. While researching technical topics, I also came across useful public record information through Wood Court Index which can be helpful for finding organized legal information. Your explanation makes the router settings much easier to understand for beginners.
