dis int <-(预示端口状况)

Ethernet1/0 current state :UP

Line protocol current state :UP

Description : Ethernet1/0 Interface

The Maximum Transmit Unit is 1500, Hold timer is 10(sec)

Internet Address is <---(找到公网地址的端口)

IP Sending Frames'''' Format is PKTFMT_ETHNT_2, Hardware address is 000f-e24b-90c1

Media type is twisted pair, loopback not set, promiscuous mode not set

100Mb/s, Full-duplex, link type is autonegotiation

Output flow-control is disabled, input flow-control is disabled

Output queue : (Urgent queuing : Size/Length/Discards) 0/50/0

Output queue : (Protocol queuing : Size/Length/Discards) 0/500/0

Output queue : (FIFO queuing : Size/Length/Discards) 0/75/0

Last clearing of counters: Never

Last 300 seconds input rate 76409.96 bytes/sec, 611279 bits/sec, 221.16 packets/sec

Last 300 seconds output rate 169645.62 bytes/sec, 1357165 bits/sec, 217.84 packets/sec

Input: 84913558 packets, 1899317081 bytes, 84913558 buffers

[H3C]int e1/0

[H3C]nat server protocol tcp global www inside www

[H3C]nat server protocol tcp global 22 inside 22

[H3C]nat server protocol udp global snmp inside snmp

[H3C]nat server protocol udp global snmptrap inside snmptrap <--(一看就大白tcp/udp是以及谈，www是80,snmp以及snmptrap是161.162端口)

[H3C]dis thellos

interface Ethernet1/0

ip address

firewall packet-filter 3000 inbound

nat outbound 3001 <--(这是客户上彀用的地址池不消管，其它的`就是端口照射了)

nat server protocol tcp global www inside www

nat server protocol tcp global 22 inside 22

nat server protocol udp global snmp inside snmp

nat server protocol udp global snmptrap inside snmptrap

思科网络的端口照射原理是同样的号令纷歧样罢了，这搭只给出配备布置。

思科网络#config t

思科网络(config)Ip nat inside source static tcp 80 80

思科网络(config)Ip nat inside source static tcp 22 22

思科网络(config)Ip nat inside source static tcp 161 161

思科网络(config)Ip nat inside source static tcp 162 162
