锐捷学习笔记-5（nat）_锐捷nat配置

锐捷NAT配置加简单ACL
配置ACl
ip access-list standard 1 
10 permit 192.168.10.0 0.0.0.255
20 deny any 

配置nat地址池
ip nat pool  1 1.1.1.1 1.1.1.1 netmask 255.255.255.255

配置nat内、外网口
 int  g 0/0
ip nat inside 
int g 0/1
ip nat outside

配置nat转换策略
ip nat inside source list 1 pool 1 overload

acl配置扩展
ip access-list standard 1 (1-99) 标准acl
ip access-list extended 100 (100-199) 扩展acl
ip access-list standard/extended word

show access-list       /查看acl

nat地址池配置
ip nat pool 1 1.1.1.1 1.1.1.1 netmask 255.255.255.255 
ip nat pool 1 netmask 255.255.255.255
address 1.1.1.1 1.1.1.1

源
静态nat
基于IP
ip nat inside source static 172.16.1.100(内) 192.168.2.168（外） permit-inside 
基于TCP UDP
ip nat inside source static tcp 172.16.1.100(内) 23（端口号） 192.168.2.168（外） 23

show ip nat teanslatons 查看NAT转换表

外部源（转换目的地址）
基于ip
ip nat outside source static 1.0.23.3 192.168.10.100
当内网访问192.168.10.100时源地址会转换为1.0.23.3 

基于TCP UDP
ip nat outside source static tcp 1.0.23.3 192.168.10.100

nat做tcp的负载均衡
 ip access-list extended 100
10 permit ip any host 1.0.0.100

ip nat pool 1 192.168.1.1 192.168.1.2 netmask 255.255.255.0 type rptary 

ip nat inside destination  list 100 pool 1
