[BUG] 负载均衡TCP端口映射通信异常

[yulongz]

问题描述/What happened:

通过负载均衡映射了云主机端口到公网IP，在使用的过程中发现不同网络环境下导致云主机连接异常。目前映射的端口为TCP方式，内网端口为22或80端口，都出现了如下问题。 目前已发现并测试的情况如下： 1、客户终端(手机/笔记本/台式机)在手机或手机热点环境下，通过负载均衡地址及端口可正常连接到云主机； 2、客户终端(手机/笔记本/台式机)在宽带环境下 ，通过负载均衡地址及端口无法正常连接到云主机，云主机IP及端口能通但数据不能正常返回。

环境/Environment:

• OS (e.g. cat /etc/os-release): cento7.9
• Kernel (e.g. uname -a):5.4.130-1.yn20230805.el7.x86_64
• Host: (e.g. dmidecode | egrep -i 'manufacturer|product' |sort -u) Manufacturer: Hynix Manufacturer: Inspur Manufacturer: Intel(R) Corporation Manufacturer: LITEON Product Name: NF5280M5 Product Name: YZMB-00882-104
• Service Version (e.g. kubectl exec -n onecloud $(kubectl get pods -n onecloud | grep climc | awk '{print $1}') -- climc version-list):
