ProxyDNS v1.0.1

A tool to bypass DNS-based internet censorship when port 53, or even DNS packets themselves, are blocked by a firewall.

You must run rpi_image.sh with sudo!

Bugs

• no udp connection tracking (for > 1 packet queries), tcp is ok

• no multithreading (slower)

• no error checking for atoi etc

• It never renews the DHCP lease (on embedded version)

To find DNS servers not on port 53

• https://www.google.com/search?client=safari&rls=en&ie=UTF-8&oe=UTF-8&q=%22iptables+-t+nat+-A+PREROUTING+-i+br0+-p+udp+--dport+53+-j+DNAT%22+-nvram&tbs=li&filter=0
