我在Redhat 9.0用vmware装了FreeBSD,请问怎么两个系统同时上网？
不一定要详细的，给点指示我吧，我一点头绪都没有！！！
先谢了！~~~~

在配置vmware虚拟机时使用网桥模式，bridged network，并给bsd分配一个和主机类似的IP，例如主机是10.0.0.5，可以给bsd分配10.0.0.6，其他配置和主机一样。总而言之，就象局域网中的另一台机器。如果这两个IP都被允许上网，那这两个系统也都可以上。

谢谢，但我是用动态的ip，是用电信的ADSL上网。而且ISP不允许重复拔号。
能不能把主机做能路由器？真的一点都不懂的说

只能用一个IP，那做端口映射行吗？没弄过，一点都不懂。
