Kiran,

So, what you want to do is set up a network address translation, or NAT. I am going to assume that that one public IP address is the same address that your router uses. This means you need to set up a one to many or port address translation (PAT) with overload. There is a ton of info on the Internet to help get you through this but the basics are as follows:

Create a standard access list specifying the IP of the PC you wish to access the Internet (if you add more PCs in the future, just add them to this access-list and they, too, will get Internet access):

ip access-list 1 permit host 192.168.1.10

Next, create the NAT:

ip nat inside source list 1 interface FastEthernet1/0 overload

Where the #1 specifies the access-list from above and FastEthernet is actually your external interface on the route, the one with the 175.101.6.69 IP address assigned to it.

If you have a different IP address assigned to the outside interface, please respond and include additional information like do you need to access the PC from the Internet.

Good luck!
