DoS attack, Teardrop or derivative, Ping of Death, strange non-DHCP IP address connected to wifi
I'm getting lots of Dos attacks logged in my C3000 modem/router. They appear to be coming from inside my network, from my wifi. I keep seeing a device attached to my wifi with an IP address of 1.1.15...
Disabling a port scan is a protection that prevents an external source from port scanning. (having it checked enabled the protection.)
Enabling DOS protection (checking it) protects you as well.
I think you simply misinterpreted what those meant. Most consumer routers (netgear included) ship with all protections turned on.
"By default, the router uses port scan and DoS protection (it is enabled) to help guard a network against those attacks that inhibit or stop network availability. If someone selects the Disable Port Scan and DoS Protection check box on the WAN screen, that disables the protection."
That is from the netgear site. The default factory settings on the router I received had it checked. I did not change it. On my other netgear routers it is unchecked as delivered which is correct. I'm getting the dos attacks and port scans on the new router as described by others in this post. Having these disabled by checking that box, may have contributed I now can not stop these attaacks as others in this post have said. IOS devices have their ips on the router changed which seems like a virus on the router. I will update the firmware and NOT check the box
