Block external IPs on Comtrend WAP-5813n
Block external IPs on Comtrend WAP-5813n
Hello, I need to prevent traffic from certain external IP addresses. My router is a Comtrend WAP-5813n, and I've tried using the IP filtering feature but it didn't work. My goal is to stop packets from that specific IP from reaching my network. In simple terms, I want any data coming from that direction to hit a barrier—like a firewall—that blocks it completely. Currently, I can only filter URLs, not full IP addresses. My ISP also doesn’t allow me to adjust parental controls, so I’m stuck with this limitation. Can you help me find a way to achieve this?
The issue arises when you start sending data to an IP through a specific port. You'll still get packets even if a firewall is in place. Once the connection stops, the external IP won't be able to reach it, as any typical router firewall will prevent it. To stop incoming traffic from a particular IP, you must restrict the internal IP from accessing that device. For instance, you could assign 192.168.1.2 to be blocked from reaching 216.58.201.142, ensuring only that specific device is affected.
I need to use that IP address for another project later. I plan to build on this idea. My IPTV decoder gets video packets from ISP servers and processes them into playable video. To generate channels such as CNN or CBS, the ISP broadcasts each channel using a unique IP, like CNN being 239.0.0.40 on port 8208. If I don’t want CNN, I can use my PC to send the signal through that IP. VLC or similar tools should work fine, but it doesn’t recognize the source as ISP because it’s coming from my local network. I can see the video I want, but disconnecting the decoder from the internet prevents it from receiving any ISP video. As you probably already noticed, I can’t tell the decoder to ignore that IP address, since doing so would also block my own attempts to broadcast from my PC. Thanks for reading this far.
