思科ASA 8.4端口转发

我在Cisco ASA上从互联网上的主机到内部networking上的主机端口转发遇到问题。 ASA的外部接口通过DHCP进行分配。 为了使这个工作正确，还有其他事情要做吗？

更新到问题

(outside) to (outside) source dynamic VPN_NETWORK interface

• 尝试从2个外部IP设置到相同的私有IP的NAT
• 什么决定了Cisco路由器的最大吞吐量？
• 在10Gb的cat6a电缆上使用cat5e补丁/插口可以吗？

 (outside) to (outside) after-auto source dynamic VPN_NETWORK interface 

数据包追踪：
