# Udp2raw-tunnel
![image0](images/image0.PNG)
An encrpyted, anti-replay, multiplexing UDP tunnel which tunnels UDP traffic with fake TCP or ICMP header using raw socket. Also acts as a connection stablizer.
An Encrpyted,Anti-Replay,Multiplexed UDP Tunnel which can help you Bypass UDP Block or QoS by tunneling UDP traffic through Fake-TCP or ICMP by using raw socket.It aslo acts as a Connection Stablizer.

# Features
### Send / Receive UDP Packet with fake headers
Fake headers help you bypass UDP blocking, UDP QOS or improper UDP NAT behavior on some ISPs. Raw packets with UDP headers are also supported, in this mode you can just use the encrpyting,anti-replay and connection-stablize feature.
### Send / Receive UDP Packet with fake-tcp/icmp headers
Fake-tcp/icmp headers help you bypass UDP blocking, UDP QOS or improper UDP NAT behavior on some ISPs. Raw packets with UDP headers are also supported.In UDP header mode,it behaves just like a normal UDP tunnel,and you can just make use of the other features.
### Simulate TCP Handshake
Simulates the 3-way handshake, along with seq and ack_seq. TCP options MSS, sackOk, TS, TS_ack, wscale are also simulated. Real-time delivery guaranteed, no TCP over TCP problem when using OpenVPN.

### Failure Dectection & Stablization (Connection Recovery)
Conection failures are detected by heartbeats. If timed-out, the client will automatically change the port number and reconnect. If reconnection is successful, the previous connection will be recovered, and all existing UDP conversations will stay vaild.

A Linux host (including desktop Linux, OpenWRT router, or Raspberry PI) with root access.
If you want to use it on MICRO$OFT Windows, you can use VMware or Hyper-V (both bridged mode and NAT mode are supported).

### IPTABLES rule
This program sends packets via raw socket. In FakeTCP mode, Linux kernel TCP packet processing has to be blocked by a iptables rule on both sides, otherwise the kernel will automatically send RST for an unrecongized TCP packet and you will sustain from stability / peformance problems. You can use `-a` option to let the program automatically add / delete iptables rule on start / exit. You can also use the -g option to generate iptables rule and add it manually.

### `cipher-mode` and `auth-mode`
It is suggested to use AES-128-CBC + MD5 to obtain maximum security. If you want to run the program on a router, you can try XOR + simple, which can fool packet inspection by firewalls the most of time, but it cannot protect you from serious attacks. Mode none is only for debugging purpose. It is not recommended to set the cipher-mode or auth-mode to none.

### seq-mode
The FakeTCP mode does not behave 100% like a real tcp connection. ISPs may be able to distinguish the simulated tcp traffic from the real TCP traffic (though it's costly). seq-mode can help you change the seq increase behavior slightly. If you experience any problems, try to change the value.
