Routing problem

[hangyu]

I am new to IP routing . I have a server which the ip is 192.168.0.2 , the gateway is 192.168.0.5 , the server can directly connect ISP . Now , I would like to change the gateway of this server to another IP -192.168.0.8 ( for some reasons ) , but I found that the server can't connect the ISP again .
If I want to make it can connect the ISP , what can I do ? add another routing entry ? or can a server has two gateway IP ? thx

Shalom,

A server can have two gateways, but only one default gateway.

To maintain Internet Access change the default gateway back to 192.168.0.5

Use the route add command to set up a route to the 192.168.0.8 system. You say you changed this for some reason. You need to know the reason.

man route
# to help compose the route command.

There really should not be a reason to add a route here unless the systems are on separate physical networks or there is a router involved.

Hi,
did you change the default gateway or did you add a gateway address ?
Check your /etc/rc.config.d/netconf.

Machines have 1 default and normally only one gateway per card, but you could add another gateway.

what does netstat -rnv show ?
