如此配置还是无法上网，求解！

内网网段192.168.0.0
外网电信固定IP：222.77.80.8  网关：222.77.80.1
单防火墙无路由器！需要配置路由功能上网！

没有拓扑不好给意见，但是你的show run 中没有回程路由。根据你的需求假如下面直接连交换机的话，你的inside口的IP地址应该是192.168.0.1

广域网------5510 E0/0接口  222.77.80.8     
5510E0/1接口-----交换机   192.168.0.1

回程路由如何配置？ 少了回程路由会出现什么问题？

没有人懂吗？

最近我也在弄这个思科的防火墙，水平有限，不好办
