防火墙配置如上，做了出接口链路负载均衡（G1/0/0和G1/0/2）,静态路由走的内网专线在业务端ping网管都不通了（ten-G1/0/27）
你这套是F1000 V7 R8860P1210，LLB 链路负载均衡全局虚服务
virtual ip 0.0.0.0 0，所有目的 IP 的流量全部交给 LLB 策略处理，优先级高于普通静态路由。 内网专线网段10.0.0.0/8匹配到默认 LLB 策略，不再走你写的静态路由ip route-static 10.0.0.0 8 10.2.4.105（Ten-G1/0/27 专线），直接丢去两条公网链路做负载均衡，所以专线不通。
重点：
virtual-server ##defaultvsforllbipv4##%%autocreatedbyweb%% type link-ip
virtual ip address 0.0.0.0 0
lb-policy ##defaultpolicyforllbipv4##%%autocreatedbyweb%%
service enable
0.0.0.0/0 的 LLB 虚服务，会拦截所有 IPv4 流量，优先 LLB 调度，不再查路由表，这是 H3C V7 LLB 出方向负载均衡最经典踩坑点。
补充：
transparent enable只是链路组内关闭 NAT，不是让 LLB 放过内网专线网段，不解决路由优先问题。
方案（推荐，不改动现有 LLB）
新增一条 LLB class，匹配专线目的网段 10.0.0.0/8，动作配置 fallback-action continue 含义：匹配到 10.0.0.0/8 → 不做 LLB 调度，交给防火墙正常路由表转发，走你原来的专线静态路由。
参考配置
# 1. 新建ACL匹配专线网段
acl number 3000
rule permit ip destination 10.0.0.0 0.255.255.255
quit
# 2. 新建LLB class，引用ACL
loadbalance class 2 type link-generic match-any
if-match acl 3000
quit
# 3. 新建action，continue（放过，走路由）
loadbalance action skip_zhuanxian type link-generic
fallback-action continue
quit
# 4. 在LLB策略里，把这个class放在最前面（优先匹配）
loadbalance policy ##defaultpolicyforllbipv4##%%autocreatedbyweb%% type link-generic
class 2 action skip_zhuanxian
class 1 action ob$action$#for#1
default-class action ##defaultactionforllbipv4##%%autocreatedbyweb%%
quit
顺序很关键：class2（专线）写在 class1 前面，优先匹配；匹配上就 continue，不做 LLB 调度，交给路由表转发。
验证命令
# 查看LLB策略表
display loadbalance policy
# 看匹配计数，ping专线后看class2计数上涨
display loadbalance class
# 确认路由表10.0.0.0/8路由存在
display ip routing-table 10.0.0.0
备选方案（不推荐，改 LLB 模式）
删掉这个 virtual ip 0.0.0.0 0 的全局 LLB 虚服务，改成源 NAT + 策略路由方式做外网负载均衡，不再用 LLB 全局 0.0.0.0 虚服务；缺点是 Web 链路负载均衡面板的带宽统计、就近性、健康检测就不能用了。
额外风险检查
- 安全域：你的专线接口 Ten-G1/0/27 被划入
Untrust，内网 Trust 访问专线 10 段，安全策略要放行；你现在有一条rule 23 name Trust-to-Unrust action pass，策略层面是放行的，策略没问题。 - 回程：专线对端回程路由是否指向 10.2.4.106，这个也要确认。
- NAT：访问专线 10 段不要做 SNAT，你现有 nat global-policy 里目的 ip jyw（10.0.0.0/8）是 snat 到 zhuanhuan（10.2.4.106），这个是专线 SNAT，看业务是否需要；如果不需要，这条 global nat rule 要删掉，否则 10 段访问会被转换。
nat global-policy
rule name GlobalPolicyRule_20
source-zone Trust
destination-zone Untrust
destination-ip jyw
action snat object-group zhuanhuan
注意：如果专线内是同网段互通，这个 SNAT 会造成异常，按需保留 / 删除。
1. 检查路由是否生效
执行 display ip routing-table 确认该静态路由是否还在路由表中，下一跳和出接口是否正确。若路由消失，检查负载均衡策略是否误删或覆盖了该路由。
2. 检查出接口状态
执行 display interface brief 查看专线接口物理和协议状态是否 Up。若接口 Down，负载均衡可能将流量切走，需检查链路探测配置。
3. 检查负载均衡策略
执行 display loadbalance link-group 和 display loadbalance policy 查看是否将专线链路加入组并配置了健康检查。若健康检查失败（如探测失败），链路会被判定不可用，流量不再走该专线。
4. 检查NAT和策略路由
执行 display nat session 和 display ip policy-setup 确认是否有策略路由或NAT规则与负载均衡冲突，导致专线流量被错误引导。
5. 抓包验证
在专线接口执行 debugging ip packet 或镜像抓包，确认流量是否到达该接口。若未到达，问题在路由或负载均衡选路；若到达但无返回，检查对端路由或NAT。
建议优先检查负载均衡健康检查配置，这是最常见的故障点。
