Static NAT through FW

HI all,

  I am having one DSL link and internet is working in it. I need to do static natting with my internal IP. 10.100.2.25/24

Please check the diagram of it:

You didn't state what type of router you had, so I'm going to give you an example for, say, a 2800.

Assuming that you're not natting at all on the FW (from the diagram you shouldn't be), you can do something like the following on the dsl router:

ip nat inside source static 10.100.2.25 188.53.62.x

int dialer0

ip nat out

int fa0/0

ip nat in

HTH,
John

Thanks for your reply brother.

  I am having 1841 series router. And I want to configure my static nat at Firewall. My firewall is cisco 5520

which firwall ver you r using.8.2 or 8.4

I am using 8.2

static (inside,outside) 192.168.201.12 10.1.1.3 netmask 255.255.255.255

This command maps an inside IP address (10.1.1.3) to an outside IP address (192.168.201.12).
