问题描述：
公司有一条联通专线，有6个可用外网IP，MSR 通过一个Wan口链接运营商设备，LAN口接交换机，现在有6台电脑想要通过不同的外网IP访问互联网，请问该如何配置？试过配置多个一对一映射，配置后出现ARP冲突问题，同时在内网配置多个vlan，每个vlan if接口配置不同网段地址，出现只有一个vlan if网段可访问互联网，以前都是用web配置路由器，现在还在学习阶段，希望有高手帮忙看下是什么问题

您好，请知：
1、由于申请了多个外网IP地址，无需进行一对一的转换，使用basic NAT的方式，创建NAT地址池，让内网的业务IP进行动态的转换就可以了，这样又可以实现不同内网IP使用不同的外网地址去访问外网资源。
2、以下是basic NAT的典型组网配置案例链接，请参考：

3、以下是MSR2600的用户手册链接，请参考：
https://www.h3c.com/cn/Service/Document_Software/Document_Center/Routers/Catalog/MSR/MSR_2600/
4、另外如果让内网的所有网段都访问外网，需要设置ACL允许所有通过，与nat outbound address-group就行绑定即可。

请问我的拓扑和2，basic nat的典型组网配置不一样，我是在g5/0口下接一台交换机，然后把几台内网pc接到交换机上，请问需要怎么配置？
您好，是路由器的G5/0口直接接的交换机吗？这要看网关是哪里。如果网关在路由器上，路由器与交换机走trunk，交换机上创建VLAN，并将VLAN划分到端口；如果网关在交换机上，则交换机与路由器走三层互联及相互的路由指向或发布。
网关在路由器上，我在路由器的出口接口G0/0上配置命令nat noubound 2000 address-group 1 no-pat后内网PC无法上网了
您好，具体的ACL、NAT的配置是怎么样的呢？另外是否有配置默认路由往外网丢？
