Rethink: DNS + Firewall + VPN vs UDP Bus
Side-by-side comparison of two open source alternatives
Rethink: DNS + Firewall + VPN
Say hello to a safer, transparent, and secure Android. VPN: Connects to multiple WireGuard VPNs of your choice. Safe: Reveals network activity of installed apps and lets you disable, uninstall, or firewall them. Secure: First line of defense against spyware, ransomware, and malware that steal personal information and takeover accounts. Protects from DNS manipulation typically employed to censor websites, social media, and messaging apps. Fast: DNS Servers deployed to 300+ locations world-wide to ensure your internet is as fast and highly available as it can be. Open: Open source and free of any trackers. ***Features*** Firewall: Prevent apps from connecting to the Internet. Block spyware, malware, ransomware and more. A firewall blocks any app connecting to the Internet over WiFi or Mobile data. Since most forms of surveillance require the data to be sent the network to a server, firewalling them effectively mitigates the threat (File Managers, Alarm Clock, Calculator are few such examples of apps that do not require any Internet access to function). The firewall feature uses Accessibility Service to detect and firewall background applications. Monitoring: Keep tabs on incoming and outgoing Internet traffic. If enabled, the connectivity logs are collected and analyzed. Automated reports flag previously unknown or suspicious connections, and reveal the extent of attempt to steal data by spyware networks. In our tests, around 60% of the traffic is flagged and reported as being initiated by known spyware. Logs generated are made available in near-real time to the user for their own analysis. WireGuard: Secure outgoing Internet traffic. The app uses fast, modern, light-weight, and secure WireGuard protocol to encrypt outgoing connections to any compatible VPN provider of your choice. Anti-censorship: The app encrypts your internet connection to Domain Name System (DNS) server run by Rethink with presence in our 300+ locations world-wide. DNS servers are the address book of the internet: A DNS server provides the exact addresses you need to visit a website or open an app. Data Monitor: Track per-app and per-connection Mobile or WiFi data usage.
UDP Bus
android-udp-bus is an application to create UDP forwarders, hubs and other tools. To aid building VPNs, video streaming and other tricky network uses. Features: * Binding UDP socket on specified port and exchanging traffic between all known peers * Exchanging traffic between multiple UDP sockets * Remembering specified number of peers that have sent us some datagram, with optional expiration policy * Directly specifying peers to send datagrams to. Combined with remembering, it allows using the application as UDP forwarder. * Joining multicast groups, setting TTL, TOS, read and write buffer sizes and other socket options. * Periodical sending of hardcoded datagrams to specified peers (e.g. to keep NAT open) * Displaying of detailed statistics of the traffic * Starting multiple isolated hubs, each with distinct set of ports. Can even act as a simplistic load balancer due to SO_REUSEPORT. The application does not send datagrams back to sender. Limitations: * UI is not user-friendly. * Not all features are exposed in GUI - you may want to add some undocumented fields to the JSON manually. * Not very optimised for speed or latency. It may be slightly slower than socat udp4-l udp. * Not everything is tested yet * Documentation is lacking
