maybe you need to run something like route add -host 188.72.255.289, but it's uncommon that gateway is not in the same net..
-- Eero
did you get the attachment i am adding again , 188.72.255.189 already added but there is sth. different with fedora which is working with bridged connection esppecially gateway, beside this i could not ping my own gateway there are 4 other windows machines and all of them working perfect

I'm not reading your attachments, frankly, I'm surprised the mail list server didn't strip them as attachments are frowned upon on email lists.
now you're saying you have a bridged connection to? whats being bridged? is there anything else you're not telling us about? the network as given in the body of your emails is an illegal configuration

fedora's eth0 has an unconventional route to the gateway via eth0 (the first line)
this is an odd network, i see like 4 different subnets all mashed up on the same physical network segment? who designed this? surely not someone with a proper network engineering background..
Fedora 12 designed automatically and i need same settings because centos is in the same machine with fedora under vmware ... the only one difference is fedora's ip address 78.159.97.xx and centos is 188.72.255.189 everything else same

this is given by datacenter and 188.72.255.188 my webserver's static ip

That doesn't make sense. They should give you a gateway address that is within the range of your own IP's netmask. If it works at all under any OS it must be because the gateway router is proxy-arp'ing for anything it can reach.
it workeddddddddddddd thankes every body i had a problem with activating network card :D
[root@lin2 ~]# route add default gw 217.20.117.1 dev eth0 [root@lin2 ~]# route add host 217.20.117.1 netmask 255.255.255.255 dev eth0
that is solution

Automagical setup:

The *assumes* that the network (switch or router box) that eth0 is connected to also has 217.20.117.1 connected to it. Typically a router 'box' contains both the router and a ethernet switch: a 'pure' router would only have two ethernet jacks, one for each of the two networks the router routes between. Since there is no great demand to put a single machine on a network and since the switch hardware is dirt cheap and since no one does coax Ethernet anymore, modern router boxes include a switch in the 'inside' network.
i tryed this : [root@lin2 ~]# route add default gw 217.20.117.1 dev eth0 the answer siocaddrt : network is unreachable
