I need your help.
Please, help me!!
I know that many hosts can access to the internet using NAT with only a few public address.
The my task is to complete the NAT configuration using all IP addresses assigned by the ISP to provide Internet access to the hosts in the company LAN.
And, I am wondering whether use Overload keyword or not. Just, do I need overload?
And, may I use a few pulic addresses to use overload keyword?
I saw that overload use a single public address from Cisco book. is it right?
And, I don't know wildmask and subnet well.
Please, let me the configuration in details...
Boss requested me the NAT configuration, saying the following situations.
Maybe, I guess that he test me...
Please, help me!
If I have the following ip addresses,how can I configure NAT?
#1:
Router name: AAA
inside global addresses: 198.18.32.217 -192.18.32.222/29
inside local addresses: 192.168.57.33 - 192.168.57.62/27
Number of inside hosts: 30
My answer:
??? indicate that I don't know how to configure.
Assume NAT pool named net-62...
AAA#config t
AAA(config)#ip access-list 5 permit ??? (I don't know widmask and subnet well.. sorry.., please, let me know in details)
AAA(config)#ip nat pool net-62 ??? (192.168.57.33 192.168.57.62? netmask)
AAA(config)#ip nat inside source list 5 pool net-62 overload? (Should I use overload keyword?)
AAA(config)#int fa0/0
AAA(config-if)#ip add -missing-
AAA(config-if)#ip nat inside
AAA(config-if)#exit
AAA(config)#int s0/0
AAA(config-if)#ip address -missing-
AAA(config-if)#ip nat outside
AAA(config-if)#end
AAA#copy run start
Please, answer the configuration in details...
