hello I am a Newbe to Cisco. I am trying to Nat an internal address 10.40.1.8 to three external address. 126.96.36.199-172 on a pix 501. I am using PDM. When I am on the external net work I can’t ping or access the 188.8.131.52 address. Can anyone telling me what I am doing wrong?
First of all lets understand why and what all changes you can make on your config.
As per your current config you have defined the outside Global address pool to use the 3 ip address which are 184.108.40.206-172. This means that whenever any host from your internal network tries to go out and access the internet it would be translated into the ip address range from the following address pool you have defined. I would recommend the command
global (outside) 1 interface
Second the static command that you have defined in your config tells your firewall to not to translate the ip address 10.40.1.8 when it tries to go out and access the internet (as per my assumption). so i believe you would not require this command in your config.
Thirdly the command you have defined in your dhcp only allows two machines from your internal network to get an ip address from your pix firewall.
Now as per the issue your running into you need to map 3 different external ip address to one internal ip address. Well as far as i know thats not possible till now.
Secondly if you want that your internal ip address to be translated to only one single ip address then you can create the static translation which would be
static (inside,outside) 220.127.116.11 10.40.1.8
Note :- make sure that you have removed the two above commands which are before making any changes in your config
1) static (inside,outside) 10.40.1.8 10.40.1.8 netmask 255.255.255.255 0 0
2) global (outside) 1 18.104.22.168-22.214.171.124
