Hello Barry,

Thanks for your blog.

I plan to block some ports on our router, which are shown in your blog.

Step 1 on the list …. Deploy Exploitable Port Filtering on the edge of your network ….

Some of our routers use Linux as the operating system, so I plan to use nftables to make some filtering rules.

Best,

Brandon Zhi
