When i restart then cannot connect already. Why?

After i add the default gateway to mail.fschan.com then
"[root@fish root]# route add default gw mail.fschan.com" enter command "[root@fish root]# route -n" the output is below:
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
202.157.213.128 0.0.0.0         255.255.255.248 U     0      0        0 eth0
192.168.2.0     0.0.0.0         255.255.255.0   U     0      0        0 eth1
169.254.0.0     0.0.0.0         255.255.0.0     U     0      0        0 eth1
127.0.0.0       0.0.0.0         255.0.0.0       U     0      0        0 lo
0.0.0.0         202.157.213.131 0.0.0.0         UG    0      0        0 eth0
 After that, i can connect to the internet. But when i restart again then cannot connect to internet. I have to repeat again to type the command "route add default gw mail.fschan.com" then after that can connect throught internet. Why? Have any way to solve this problem?
Thank you.

Is your system getting its IP via DHCP or is it statically assigned?

In the case of a static configuration the network parameters may not include a definition of the default route. On a RedHat system or similar this is set by "GATEWAY=202.157.213.131" in /etc/sysconfig/network.

A system that gets its IP via DHCP should get the default gateway setting from the DHCP server.

"route add default gw mail.fschan.com"

I have to say that unless you have an entry for mail.fschan.com in your /etc/hosts file I cant understand how this command works :) In order for linux to resolve a host name it needs to be able to access dns servers. You would normally have to be connected to the internet to access dns servers. Unless you have a local dns server?
