基于telnet的NAT负载均衡
一、路由器配置
R1#sh run
interface Ethernet0/0
ip address 192.168.1.1 255.255.255.0
ip route 0.0.0.0 0.0.0.0 192.168.1.2
R2#sh run
interface Ethernet0/0
ip address 192.168.1.2 255.255.255.0
ip nat outside
ip virtual-reassembly
half-duplex
interface Ethernet0/1
ip address 192.168.2.1 255.255.255.0
ip nat inside
ip virtual-reassembly
half-duplex
ip route 192.168.0.0 255.255.255.0 192.168.1.1
ip nat pool p01 192.168.2.2 192.168.2.3 prefix-length 24 type rotary
ip nat inside destination list 101 pool p01
access-list 101 permit ip any host 192.168.1.2
R3#sh run
interface Ethernet0/0
ip address 192.168.2.2 255.255.255.0
ip route 0.0.0.0 0.0.0.0 192.168.2.1
interface Ethernet0/0
ip address 192.168.2.3 255.255.255.0
ip route 0.0.0.0 0.0.0.0 192.168.2.1
二、验证
R1#telnet 192.168.1.2
Trying 192.168.1.2 ... Open
User Access Verification
Password:
R4>exit
[Connection to 192.168.1.2 closed by foreign host]
R1#telnet 192.168.1.2
Trying 192.168.1.2 ... Open
User Access Verification
Password:

R2#sh ip nat translations
