full-nat 有计划开源toa模块么 about dpvs

[lvsgate]

https://docs.ucloud.cn/security/uads/faq/game
http://ddospcap.ufile.ucloud.cn/toa_centos6.5_v2.tar.gz
http://ddospcap.ufile.ucloud.cn/toa_centos7_v3.tar.gz
ucloud有源代码下载，直接编译安装，不需要重新安装内核和重启系统。
但是ucloud吧OPT_CODE改成252了，你要改成跟dpvs一致

记得modprobe toa，还要加到开机启动里去
cat /proc/net/toa_stats检查

TCP option format for TOA is not changed, 2.6 RS with TOA module installed should able to get client IP.

有没有针对取client ip 的配置 我测试了阿里的full-nat 后端的RS可以取到真实的client ip，dpvs 取到的client ip 是 LIP，测试中 使用同一个RS

[SchoIsles]

在rs上tcpdump抓包，wireshark打开看看，options里的内容是什么

[beacer]

@xiujie-jiang is the issue fixed ? if not, pls show the TCP address option by tcpdump or wireshark.

You can try https://github.com/Huawei/TCP_option_address.git

@lvsgate 我们目前项目用的rs是 lvs_v3的toa，发现能兼容 lvs_v2 和 lvs_v3 (tcp option格式没变？)， 想请问一下，这个是那个版本的 tcp option呢？

[beacer]

As discussed above, TOA is already "open-sourced" by other companies, the real servers (RS) for DPVS can use them.
Pls check tutorial.md to found the TOA resources.
