This project is based on original rt-n56u with latest mtk 4.4.198 kernel, which is fetch from D-LINK GPL code.

Extra functions / changes

• Adding user/chinadns-ng , and fix shadowsocks + chinadns-ng using local domain whitellist.
• AP Relay auto-daemon

SS/SSR

• Transparent proxy (iptables) wasn't cleaned completely, this issue is fixed.
• Adding DNSProxy , Local DNS integrated with SS/SSR
• Dnsmasq optimization specially for SS/SSR
• Resolve DNS pollution - Adding DNS i/p in china-route mode
• Fast-open option is enabled according to linux version

Enhancements in this repo

• commits has beed rewritten on top of hanwckf/rt-n56u repo for better history tracking
• Optimized Makefiles and build scripts, added a toplevel Makefile
• Added ccache support, may save up to 50%+ build time
• Upgraded the toolchain and libc:
  • gcc 10.5.0
