RADIUS 服务器进行 MAC 验证 , 配置 nat ,使无线接入端连接外网 一、 实验目的:通过 Radius 服务器的 mac 验证和路由器上的 nat 配置,使得在局域网内的无线设备可以上网。
二、实验拓扑图:
三、使用的设备列表:
S3610交换机 3台
AR28路由器 1台
AP 无线路由器 1台
AC 无线控制器 1台
Radius 服务器 1台
四、具体的配置:
步骤一:在 AC 上设置用户和做 mac 地址绑定,以及设计无线 网
＜h3c>sys
[h3c]sysname AC( 注意, AC 为 WA2620-AGN ,本 AC 改名字的时 候不能只打 sys+名字,需要的是完整才能打出来 sysname+名字 ) [AC]int vlan 1

[AC-radius-yu]primary accounting 192.168.5.1
[AC-radius-yu]key authentication h3c(radius 上默认的密钥为 h3c , 可以重设,所以在配置上需要一致,所以这里配置 h3c )
[AC-radius-yu]key accounting h3c
[AC-radius-yu]user-name-format without-domain(注意:这条指令的 意思是,不用域名,让你在 radius 添加账户时可以不带域名 )
[AC]radius scheme yu

[dhcp]dhcp server forbidden-ip 192.168.1.254
[dhcp]dhcp server forbidden-ip 192.168.2.254
步骤四:作为连接所有设备的交换机,配置其中继功能
[sw]vlan 2
[sw-vlan2]vlan 3
[sw-vlan3]vlan 4
[sw-vlan4]vlan 5
[sw-vlan5]vlan 6
[sw-vlan6]quit
[sw] dhcp relay server-group 1 ip 192.168.3.1
[sw]int vlan 1

[sw-Ethernet1/0/8]port trunk permit vlan 1 to 2 4 [sw]int e1/0/24
[sw- Ethernet1/0/24]port access vlan 3
[sw]rip 1
[sw-rip-1]network 192.168.1.0
[sw-rip-1]network 192.168.2.0
[sw-rip-1] network 192.168.3.0
[sw-rip-1] network 192.168.4.0
[sw-rip-1] network 192.168.5.0
[sw-rip-1] network 192.168.6.0
[sw]dhcp enble
[sw]ip route-static 0.0.0.0 0.0.0.0 192.168.6.1(这里指向下一跳的地 址,即连接外网的路由器的接口地址 )
步骤五 :配置路由器上的路由功能
[RA]acl number 2000
[RA-acl-basic-2000]rule 1 permit source 192.168.2.0 0.0.0.255 [RA-acl-basic-2000]rule 2 permit source 192.168.6.0 0.0.0.255 [RA]rip
[RA-rip]network 192.168.2.0
[RA-rip] network 192.168.6.0
[RA]int e0/0
[RA- Ethernet0/0]ip add 192.168.6.1 24
[RA]int e0/1
[RA- Ethernet0/1]ip address 10.3.102.33 24
[RA- Ethernet0/1]nat outbound 2000
[RA]ip route-static 0.0.0.0 0.0.0.0 10.3.102.1
至此,基本配置全部完成
步骤五:测试配置结果
查看 3层注册是否成功
假如 3层注册不成功,我们应该一环环进行检查, ping 测试 AC ping switch测试
DHCP ping switch测试
3层注册成功后,我们检查下 DHCP 获取情况
建立起 RADIUS 服务器
手机连接过程与结果
手机客户端连接后的 DHCP 获取情况
查看一下路由器上 nat 转换的情况
接下来看看我们连接的手机是不是可以正常的上网
