Problem with pinging computers on other subnets with NAT

Hello everyone
I have pretty easy problem but i cant get how to fix it.
I have 2 Servers that are linked on same subnets on them eth. interfaces ( server o1 have 10.0.0.1 
IP adr and server 2 has 10.0.0.2 adr ). Additionally first has second eth interface that is  connected to internet interfaces ( 192.168.1.2 ) and has already configured in RAS NAT for that 
interface. Its working fine.


The second server has either second network adapter that its working on 11.0.0.0/24 subnet. He is 
default GW for this scope and has already configured to nat this scope to 10.0.0.x interfaces. Its 
working fine - clients from this scope has acess to internet and can ping computers from 10.0.0.x 
scope.

Problem : 
Clients from scope 10.0.0.x cant ping computers from scope 11.0.0.x.
I have tried configure statistic route on server 1 :
11.0.0.0 mask 255.255.255.0 gw 10.0.0.2 metric 1

But it still doesnt work
When im trying check tracert there is information : Request timed out.
