Hi,

your server with 8.8.8.8 must have an ip address in the 88.84.121.0/24 network. How did you configure your server?

Is the default gateway of the PC correctly configured(192.168.1.1) and in same subnet as the ip of the machines ?

hi, web server just have a single ip address without any gateway, and yes all pc has default gw of 1.1. i can able to ping 88.84.121.121 ip.

Hi,

then this won't work because routing is done first before NAT and you don't have a route for 8.8.8.8 on the router and the server has got no route for 88.84.121.0/24 as it has no connected interface in that subnet.

change your server address to 88.84.121.2/24 and you'll be natting your inside subnet.
