pix 501 static 不通问题

ip address outside 60.191.x.54 255.255.255.248

access-group acl_out in interface outside
route outside 0.0.0.0 0.0.0.0 60.191.x.49 1
其他配置都是基本配置，就是这几句关于静态nat。在pix上ping inside ，outside 都没问题。可就是ping不通这个映射的公网地址。而且打开的端口也全部访问不到。
pix为pix 501，pix os 6.3
大家帮我看看可能是什么问题。

你做NAT地址池了吗？
还有外网IP对内网IP的映射?
