Instead of creating one rule that covers tcp/udp (the default option). I checked and I hadn't turned off WAN side access on the ISP's Huawei device, and once I did that (for both WAN and ONT access) and re-ran the Avast network scan, it said everything was fine. Com/myxFi or open the Xfinity app and sign in with your Xfinity ID and password. I didn't really like the dual router but had to leave the ISP configured mostly as it was (as a router) to avoid other issues, and already had my own much nicer router when I moved here. In my case I am running my own router behind the ISP's Huawei HG8245 fiber gateway. I received the same error about my router being open to the Internet and being infected. This sure seems like a false claim to scare folks into buying the Avast SecureDNS feature. UDP (User Datagram Protocol): UDP is also. It is used by application protocols like HTTP and FTP. It is better than UDP but due to these features it has an additional overhead.
? What evidence is Avast using to identify that my router is infected or hacked? TCP (Transmission Control Protocol): TCP is a layer 4 protocol which provides acknowledgement of the received packets and is also reliable as it resends the lost packets. (Why is this less important than your admin interface is accessible?)Ĭhecking the DNS on the router which fronts my home network to the cable modem, shows the primary and secondary DNS entries to be what the Cable ISP (Comcast) is using. Scrolling down on the "accessible" notice is an even more concerning claim: "Your router is infected" and "Your router has been hacked and its DNS settings have been modified to serve malicious contents." Since TCP is a connection-oriented protocol, it relies on a server in a passive open state. ? How do I find out what admin interface Avast thinks is accessible? TCP is connection-oriented while UDP is connectionless. I have two wireless bridges configured behind a wireless router, all with strong security settings, and their admin interfaces are not remote accessible.
(It also says this may be a false positive from port forwarding - and I do have some ports forwarded to another machine, but no admin page is accessible.) "Your router is accessible from the Internet" - claiming "we have found that your admin interface can be accessed by anyone on the Internet"
