Hi,
[root@localhost root]# ping 172.25.25.25 http://172.25.25.25 ;Gateway connect: Network is unreachable
your gateway should be in the same network. Your ip is 172.25.65.29 http://172.25.65.29 which is not in the same network as your gateway. why have u chosen this network with only 2 hosts? I think this kind of network is chosen for routers if i am rite where there is no need for more than 2 hosts. either your 172.25.65.30 http://172.25.65.30 should be a gateway to 172.25.25.25 http://172.25.25.25 or your computer should in the same network as ur Internet gateway.
