Hi, I recently bought the GL-AR750 and setup a Shadowsocks transparent proxy (the server is hosted on GCP). I noticed that the connection occasionally goes down for a few seconds/minutes and I’m having trouble troubleshooting the issue (I’m using it in China). I am now trying to enable ChinaDNS so I went in to “Applications/China DNS” and enabled it. What does the “Enable Bidirectional Filter” option mean? Also, is just enabling it there enough for my DNS queries to go through it or do I have to setup something in other DNS sections (e.g. [http://192.168.8.1/cgi-bin/luci/admin/network/dhcp](http://192.168.8.1/cgi-bin/luci/admin/network/dhcp) or [http://192.168.8.1/cgi-bin/luci/admin/services/dns-forwarder](http://192.168.8.1/cgi-bin/luci/admin/services/dns-forwarder))? How can I test that ChinaDNS is working from my laptop? Thanks! Here’s some screenshots of my configuration, let me know if anything looks wrong: ![combined](https://forum-static.gl-inet.com/original/1X/72538f7d4b77505a725abff07c4946615b588a77.png) ---

I recommend you flash the 3.0 testing firmware, you can install the ss [plug-in](https://docs.gl-inet.com/en/3/app/ss/), and enable cloudflare. ---
