Review on TRENDnet 4-Port Broadband Router with MAC Address Control, Remote Management & High-Speed Switch Ports - Black TW100-S4W1CA by Melota Phillips

Hardware: Arris BGW210-700 with IP passthrough with fixed DHCP configuration, WiFi and firewall disabled (virtually all unnecessary things have been disabled) and with this TWG-431BR Router, which in turn is connected to the TP-Link TL-SG1016DE switch. For testing, I used a Dell Latitude e6320 with an integrated Intel 82579LM network card running Ubuntu 20.10 connected to a TP-Link switch. All firmwares have been updated. Configuration: The TWG-431BR was configured manually as there was no configuration wizard. WARNING: Make sure you enable IP address filtering rules as there was a bare minimum that kept DNS open and most closed (see GRC ShieldsUp! comment below). UPnP is not supported by this router and make sure you download and read the manual especially if you are not familiar with configuring firewalls for business devices. The rating should have been 3 stars because the default firewall security status is "not right", but I gave it 4 because Trendnet tech support answered my question. Questions emailed immediately when I set up the firewall tests: GRC ShieldsUp! confirmed everything was protected as closed if default firewall security stayed the same (WARNING: the DNS port was open and the rest was closed) GRC ShieldsUp! confirmed that everything was protected as hidden when IP filter rules were set to deny all incoming requests (however it didn't respond when checked BUT ran cross checks which I haven't figured out how to do yet turns off) DSLReports speed tests gave a C for bufferbloat but I couldn't fix it, although it has a QOS bandwidth control that messed up DNS resolution when enabled (upload speed was 300-500Mbps, Upload speed was about 933 Mbit/s). AT&T speed test I used Ookla showed 15-18ms ping, 0-2ms jitter, 830-950Mbps download speed and 800-920Mbps upload speed
