I'm trying to secure my router as best I can from the Internet. One of the tools I use is the ShieldsUp! service at https://grc.com. The web site warns me that although all my service ports are not responding to any connection attempts (stealth), my (public) IP address is responding to pings. I use a Hitron Coda56 to connect to my cable service. The BT8 either allows or blocks pings based on how it is connected to the Internet.
-I've turned off pings from the WAN on the BT8.
-The connection between the Coda56 and the other tested devices is via an ethernet cord.
-I've tested the issue with my PC connected to the BT8 either wired or wireless.
Here is what I observed:
PC -> TP-Link Archer C8 -> Coda56 -> Internet: WAN pings blocked. (Stayed this way for years through four cable modem changes. The Coda56 is my newest cable modem.)
PC -> Coda56 -> Internet: WAN pings blocked.
PC -> BT8 -> Cellphone tether on the USB port -> Internet: WAN pings blocked.
PC-> BT8 -> Coda56 -> Internet: WAN pings allowed.
Is there another setting I'm missing?
