Question: How can I save static routes I set up in my Fedora/RedHat/CentOS Linux after I reboot server?
Answer: In Fedora Linux (or RedHat, CentOS) you can set up static routes for certain network interface (for example eth1) by editing file /etc/sysconfig/network-scripts/route-eth1.
For example, you have to save static route added by the following command:
route add -net 192.168.0.0 netmask 255.255.255.0 gw 192.168.100.1 dev eth1
To do it, just add the following line to /etc/sysconfig/network-scripts/route-eth1:
ADDRESS0=192.168.0.0
NETMASK0=255.255.255.0
GATEWAY0=192.168.100.1
