NAT help

Hello,

I am new to this forum (officially) but have used it several times for much needed help.

My question is regarding NAT and Ill try to make this as brief as I know how.

I have a cisco 2821 router that has G0/0 as my outside NAT to a private 192.168 network.  My G0/1 is my NAT inside, also a private network of 10.

My 192.168 network resides on a Modem which also does WiFi. I'm not overly impressed with the modem due to its lack of configurability.

Devices on the 192.168 network cannot ping anything on my 10 network due to my NAT statements. 

Is it possible to configure my G0/0 interface to allow traffic from both of these networks to go in and out? Specifically to my server which lies on the 10 network.  If so how does this work considering you can only have one statement on the interface (nat inside or outside).

Any help would be great.

 

Mark

I'd agree to Reza, as you have different networks on different interfaces, they would ping each other.

You don't need to apply NAT here.
