I have a leased line which i am using to connect to the internet using the NAT protocol. i have a pool of three real ip addresses given by my ISP of which two have been given to specific PCs(2 PCs ).
The third has been overloaded for the rest of the PCs. To my surprise only the two PCs are the ones able to browse the internet.
The following is the nat configguration:

In other words both the source static configuration are workink ok.
I tried to swap the ip addresses but still couldnt work
What could be the problem?
