    Use "Parental controls" for IoT security?

    BTW the Nest Hello just has one connection and that's to GOOGLE-CLOUD which seems fine but its upload traffic was <2KB/day for the previous few days and going up and down today, peaking at 125MB/hour. Is Traffic Analyzer straightforward to interpret or complicated by subtleties, e.g. does it...

    Use "Parental controls" for IoT security?

    Log/Connections is interesting! The tablet has been fine since a few hours before (!) rebooting it. It's the Macbook Air that's now doing most of the SSL/TLS uploads and the Nest Hello has also joined in. To test a hypothesis that a browser tab was doing the SSL/TLS uploads, I closed most of...

    Use "Parental controls" for IoT security?

    Yes, the Apps button confirms that it's almost all SSL/TLS upload traffic. The consistent upper bound might be due to rate limiting in the cable network.

    Use "Parental controls" for IoT security?

    Correction: The Mac upload traffic started when the Nexus 7 ended. Nexus 7 graph: Mac graph: What to look into now?

    Use "Parental controls" for IoT security?

    A good idea, indeed! I turned it on 4 days ago and discovered my Nexus 7 tablet uploading nearly 3 GB/day over SSL/TLS since then while just sitting and charging! It was a steady 117 MB/hour. Downloads were only 4-6 MB/hour. Today I rebooted it and uninstalled some apps, then later rechecked...

    Use "Parental controls" for IoT security?

    That's good advice. I did put most of those devices on the guest wifi. But they could still spy, join a bot net, or do other mischief.

    Use "Parental controls" for IoT security?

    ASUS router has "Parental controls" to block, per device: Adult Instant Message and Communication P2P and File Transfer Streaming and Entertainment Q. Are these controls useful at all for securing IoT devices like NAS, thermostats, and smart TVs from contacting malware or spyware servers? Q...

    RT-AC3200 Version 3.0.0.4.382.51940

    > Fixed CVE-2019-15126 ("Kr00k") vulnerability. Is it typical for ASUS to make a firmware release available for direct download to routers several days before posting it on their website?

    Keeping home and work separate?

    Many WiFi routers support WiFi guest networks, where each guest can only connect to the internet, not to other local devices. If you want an isolated network that supports Ethernet, look into the VLAN feature, e.g. https://routersecurity.org/pepwavesurfsofo.php#guestnetworks

    VPNFilter Malware

    No news. See Cisco Talos for info, e.g. "device destruction module" for files and processes that suggest a compromised device, for some models. It's an ongoing exploit, not a single malware program or a specific bug. We don't know what security holes have been or will be exploited. We don't...

    VPNFilter Malware

    Great ideas. More specific to VPNFilter, one could watch for the files and processes mentioned in the Cisco Talos blog under “'dstr' (device destruction module).” That lists "files and folders related to its own operation" like /var/run/vpnfilter that the device destruction module deletes and...

    How to remove all malware?

    Per Ars Technica, Talos found that VPNFilter targets some ASUSWRT devices, and a newly discovered module can inject malicious payloads into traffic as it passes through an infected router. (But yes, the issue is defending against and cleaning any malware.) > Williams [from Cisco Talos] said he...

    How to remove all malware?

    As far as we know, the VPNFilter malware doesn't currently put ASUS routers at risk, but the FBI believes it was created by a Russian state-sponsored cyber espionage group, so we can assume attackers are gunning for all SOHO routers. Q1. How could you remove all malware from a router? I.e. how...

    Configuring ASUS RT-AC68U to work with Google Cloud Printing?

    No, you don't need to anything special to print from outside your home network. The printer and the computer just need to both be able to make an outbound connection to Google. Here's my understanding. To use Google Cloud Print, you need: Either a GCP-ready printer or a computer running the...

    Configuring ASUS RT-AC68U to work with Google Cloud Printing?

    GCP printers should not need any router configuration. No ports, static IP, firewall, etc., unless you're normally blocking outgoing ports. Almost surely the printer makes an outgoing connection to the GCP server. This line is from my router's "System Log - Active Connections" screen: tcp...

    How to resolve this "localhost" issue?

    Similar to @AdrianB, I did: Configure the router's DHCP server to manually assign a static IP address and a name to the TV. Configure the TV to the same static IP address (Menu > Network > Network Status > IP Settings) and network name (Menu > Network > Device Name). Power cycle the TV...

    Asus RT-AC3200 Smart Connect Rules Fine Tuning

    I've yet to find a conceptual model for configuring Smart Connect nor a way to test and tune configuration settings with your clients in your environment and test if your clients can handle getting bumped to a different radio. Without that, it's just futzing around. As SmallNetBuilder writes in...

    RT-AC87R system log keeps showing old logs

    Thank you @mstombs! That explains why the log stopped working, why clearing it didn't fix it, and why deleting syslog.log-1 did fix it.

    [Beta] RT-AC3200 Firmware version 9.0.0.4.380.2695

    Has anyone here tested the hypothesis that a factory reset fixes that?

    [Beta] RT-AC3200 Firmware version 9.0.0.4.380.2695

    Do you mean device access to the internet or to the router's configuration web pages? If you mean the latter, I'm having the same problem and wondering if a factory reset will help.
