华为NAT命令看不懂，哪位大神帮我看一下

lyjycsl@sina.co

interface GigabitEthernet0/0/0
ip address 211.1.1.1 255.255.255.252
nat server protocol tcp global current-interface 8306 inside
nat server protocol tcp global current-interface 8007 inside
nat server protocol tcp global current-interface 6208 inside   为什么不写转换后地址呢？
nat server protocol tcp global current-interface 6209 inside
nat server protocol tcp global current-interface 6257 inside
nat server protocol tcp global current-interface 6224 inside
nat server protocol tcp global current-interface 22 inside 1   这里的1是和address-group对应吗？
nat server protocol tcp global current-interface www inside
nat outbound 2000  这句命令什么意思啊？
#
interface GigabitEthernet0/0/1
ip address 172.16.147.130 255.255.255.128
nat outbound 3000 address-group 1

目的到10.160.3.211或者源来自192.168.4.0的流量转换为172.16.147.132 172.16.147.254吗？

nat address-group 1 172.16.147.132 172.16.147.254

acl number 2000

rule 1 deny source 192.168.4.0 0.0.0.254

rule  5 permit

acl number 3000
rule 1 permit ip destination 10.160.3.211 0
rule 5 permit ip source 192.168.4.0 0.0.0.255
