不论你用udp2raw来加速kcptun还是vpn,为了稳定使用,都需要设置合理的MTU（在kcptun/vpn里设置，而不是在udp2raw里），建议把MTU设置成1200。client和server端都要设置。
### 提醒
`--cipher-mode xor`表示仅使用简单的XOR加密，这样可以节省CPU占用，以免CPU成为速度瓶颈。如果你需要更强的加密，可以去掉此选项，使用默认的AES加密。加密相关的选项见后文的`--cipher-mode`和`--auth-mode`。
如果要在anroid上运行，请看[Android简明教程](/doc/android_guide.md)
如果要在梅林固件的路由器上使用，添加`--lower-level auto` `--keep-rule`

用raw收发udp包也类似，只是内核回复的是icmp unreachable。而用raw 收发icmp，内核会自动回复icmp echo。都需要相应的iptables规则。
### `--cipher-mode` 和 `--auth-mode`
如果要最大的安全性建议用aes128cbc+md5。如果要运行再路由器上，建议xor+simple。但是注意xor+simple只能骗过防火墙的包检测，不能防止真正的攻击者。

### `--seq-mode`
facktcp模式并没有模拟tcp的全部。所以理论上有办法把faketcp和真正的tcp流量区分开来（虽然大部分ISP不太可能做这种程度的包检测）。seq-mode可以改变一些seq ack的行为。如果遇到了连接问题，可以尝试更改。在我这边的移动线路用3种模式都没问题。

run `make cross`，the just generated `udp2raw_cross` is the binary,compile done. copy it to your router to run.
`make cross` generates non-static binary. If you have any problem on running it,try to compile a static binary by using `make cross2` or `make cross3`.If your toolchain supports static compiling, usually one of them will succeed. The generated file is still named `udp2raw_cross`.
## Build a full release (include all binaries supported in the makefile)
1. make sure your linux is amd64 version
2. clone the repo
3. make sure you have g++ , make sure your g++ support the `-m32` option; make your your have installed libraries for `-m32` option
4. download https://github.com/wangyu-/files/releases/download/files/toolchains.tar.gz , and extract it to the right position (according to the makefile)
5. run `make release` inside udp2raw's directory
