When I first came to China about 3 years ago, I tried using a VPN service but it wasn't reliable and connecting was always slow. Other VPN providers might be doing the same thing. VyperVPN has a stealth protocol (Chameleon) which tries to obfuscate the VPN connection to make it look like other types of connections. I have read that the GFW will also try to fingerprint a server if packet analysis shows that it might be a VPN. I'd love to have a better mental model of the GFW so that I could better work remotely from there. If any of this is wrong or inaccurate, someone please correct me. I've heard from friends that GFW censorship is more aggressive around sensitive times (i.e. It's considered Chinese territory, but not under China's GFW. I'm guessing HK because it's physically and politically close. The system is dynamic, so your countermeasures have to be as well. I'm not sure on the specifics, but these attacks will cause ~90% of that connection's traffic to drop. Your vpn server) meet some criteria with some confidence, they perform attacks on that connection and subsequent connections To the same endpoint. If packets going to and from a location (i.e. Https is an improvement, but they still use machine learning to make estimates on encrypted contents of packets. Http packets are inspected to deterministically decide whether are block a connection. The simplest block sites and poison your dns cache. The Great Firewall employs many techniques for censorship. I'll take my best shot at guessing his answers. Use one VPN for US and another for UK, then use bestroutetb to build subnet lists for each country route traffic over the correct VPN. This could be used when trying to access different services (US, UK, etc.) that don't allow access from outside their country. I load the subnets for China (can private LAN) into an ipset hash and use iptables rules to exclude those subnets from going over the proxy.ĬhinaDNS and bestroutetb could be used for VPNs too. The socks5 option will try to proxy localhost & lan conections to the proxy server.Īn optimized list of subnets can be generated using bestroutetb. I use the transparent proxy option, since it allows selecting which traffic should go over the proxy. Socks5 is the easiest to use and can even do DNS lookups on the server. ShadowSocks can work as a Socks5 proxy, tunnel or transparent proxy. The foreign DNS connections are tunneled through ShadowSocks. It works by sending DNS queries to all multiple DNS server at the same time (give it a few local DNS servers and foreign DNS servers).
SHADOWSOCKS VPN UPGRADE
The port could be upgrade to 50Mbits for 25USD/month.įor DNS I use ChinaDNS to automatically filter out bad DNS results from China's censorship. I have upgrade the port to 20Mbits for an extra 10USD/month. ShadowSocks creates a new TCP/UDP connection for each connection that it proxies.Ĭheap VPS server in Hong Kong (5USD/month, 512 RAM, 2Mbit port) running the ShadowSocks server (libev version).

VPNs create one connection for all traffic (which is easier for China's GFW to detect/block/slow down). I have found using ShadowSocks to work best for me here in China.
