第一步：NAT配置
#
domain system   
 ip pool 1 192.168.1.2 192.168.1.254
#
dhcp server ip-pool 1
 network 192.168.1.0 mask 255.255.255.0
 gateway-list 192.168.1.1
#
interface Vlan-interface1
 ip address 192.168.1.1 255.255.255.0
#

第二步：wlan配置
wlan service-template 1 crypto
 ssid CMCC-wlan
 cipher-suite ccmp
 security-ie rsn
 service-template enable
#
interface WLAN-BSS31
 port link-type hybrid
 port hybrid vlan 1 untagged
 port-security port-mode psk
 port-security tx-key-type 11key
 port-security preshared-key pass-phrase cipher 12345678
#               
interface WLAN-Radio3/0
 service-template 1 interface wlan-bss 31

第三步：4G拨号配置
#
interface Cellular-Ethernet2/0
 ip address cellular-allocated
 dialer enable-circular
 dialer-group 1
 dialer timer idle 0
 dialer timer autodial 5
 dialer number *99# autodial
 nat outbound
 nat server 1 protocol tcp global current-interface 8000 inside 192.168.1.2 8000
#
 ip route-static 0.0.0.0 0.0.0.0 Cellular-Ethernet2/0
#
