how to set global ip in lan

[baorong.lai]

hi guys.

I am new to cisco .i have some basic question to ask.

in my situation .i use a cisco 1841  .

ethernet 0/0 .i set serval vlan in this port .with the address 10.x.x.x /24

ethernet 0/1 .i set a global ip in it .with address of 219.x.x.x .and i have another global ip preserved .

the nat is ethernet 0/0 ----> ethernet 0/1 .

and my question is: how to create DMZ .i want to set another global ip in my Lan.

how can i do this setting.

any suggetsion?

HI,

To use global IP to your internal LAN you need to do Static NAT for external IP to internal LAN IP.

Use below command:

ip nat inside source static  

Hope it will works.

Rate if it works for you.
