步骤一：定义全局地址 set security address-book global address Nutanix_Cluster 172.18.18.50/32 步骤二：定义协议端口 set applications application tcp-2020 protocol tcp set applications application tcp-2020 destination-port 2020 set applications application tcp-2009 protocol tcp set applications application tcp-2009 destination-port 2009 步骤三：定义目的NAT+Port之定义内网IP匹配端口 set security nat destination pool DP_Nutanix_Cluster_2020 address 172.18.18.50/32 set security nat destination pool DP_Nutanix_Cluster_2020 address port 2020 set security nat destination pool DP_Nutanix_Cluster_2009 address 172.18.18.50/32 set security nat destination pool DP_Nutanix_Cluster_2009 address port 2009 步骤三：定义目的NAT+Port之定义内外网NAT规则 set security nat destination rule-set DNAT_FROM_ISP6 rule ISP6_TO_Nutanix_2020_Owenli match destination-address-name WAN3006_162 set security nat destination rule-set DNAT_FROM_ISP6 rule ISP6_TO_Nutanix_2020_Owenli match destination-port 2020 set security nat destination rule-set DNAT_FROM_ISP6 rule ISP6_TO_Nutanix_2020_Owenli then destination-nat pool DP_Nutanix_Cluster_2020 set security nat destination rule-set DNAT_FROM_ISP6 rule ISP6_TO_Nutanix_2009_Owenli match destination-address-name WAN3006_162 set security nat destination rule-set DNAT_FROM_ISP6 rule ISP6_TO_Nutanix_2009_Owenli match destination-port 2009 set security nat destination rule-set DNAT_FROM_ISP6 rule ISP6_TO_Nutanix_2009_Owenli then destination-nat pool DP_Nutanix_Cluster_2009
步骤四：定义源区域访问内网特定区域的控制策略 set security policies from-zone ISP6 to-zone trust policy Nutanix_Cluster-OWEN-EDIT match source-address any destination-address Nutanix_Cluster application tcp-2020 application tcp-2009 set security policies from-zone ISP6 to-zone trust policy Nutanix_Cluster-OWEN-EDIT then permit set security policies from-zone ISP6 to-zone trust policy Nutanix_Cluster-OWEN-EDIT then log session-init set security policies from-zone ISP6 to-zone trust policy Nutanix_Cluster-OWEN-EDIT then log session-close set security policies from-zone ISP6 to-zone trust policy Nutanix_Cluster-OWEN-EDIT then count 步骤五：新定义之策略插入拒绝策略之前，即调整策略优先顺序 insert security policies from-zone ISP6 to-zone trust policy Nutanix_Cluster-OWEN-EDIT before policy DENY
set security policies from-zone trust to-zone ISP6 policy Nutanix_Cluster-OWEN-EDIT match source-address Nutanix_Cluster destination-address any application tcp-2020 application tcp-2009 set security policies from-zone trust to-zone ISP6 policy Nutanix_Cluster-OWEN-EDIT then permit set security policies from-zone trust to-zone ISP6 policy Nutanix_Cluster-OWEN-EDIT then log session-init set security policies from-zone trust to-zone ISP6 policy Nutanix_Cluster-OWEN-EDIT then log session-close set security policies from-zone trust to-zone ISP6 policy Nutanix_Cluster-OWEN-EDIT then count 步骤六：定义网段或特定IP从那条ISP线路访问外网资源
INGRESS_FROM_TRUST---- 在内网接口应用过滤器filter [reth3.500 zone trust]
set firewall family inet filter INGRESS_FROM_TRUST term Nutanix_Cluster from source-address 172.18.18.45/32 set firewall family inet filter INGRESS_FROM_TRUST term Nutanix_Cluster from source-address 172.18.18.50/32 set firewall family inet filter INGRESS_FROM_TRUST term Nutanix_Cluster from source-address 172.18.18.42/32 set firewall family inet filter INGRESS_FROM_TRUST term Nutanix_Cluster from source-address 172.18.18.48/32 set firewall family inet filter INGRESS_FROM_TRUST term Nutanix_Cluster from source-address 172.18.18.52/32 set firewall family inet filter INGRESS_FROM_TRUST term Nutanix_Cluster from source-address 172.18.18.55/32 set firewall family inet filter INGRESS_FROM_TRUST term Nutanix_Cluster from source-address 172.18.18.58/32 set firewall family inet filter INGRESS_FROM_TRUST term Nutanix_Cluster from destination-address 0.0.0.0/0 set firewall family inet filter INGRESS_FROM_TRUST term Nutanix_Cluster then routing-instance FORWARD_TO_ISP6 步骤七：新定义之firewall filter策略执行 then acceppt，若之前已有跳至步骤八； set firewall family inet filter INGRESS_FROM_TRUST term ACCEPT_ALL then accept 步骤八：把步骤六插入步骤七之前，即调整策略优先顺序； insert firewall family inet filter INGRESS_FROM_TRUST term Nutanix_Cluster before term ACCEPT_ALL 步骤九：查询NAT会话，确定IN AND OUT双向策略是否正确；
