[a] eth0 LAN network 10.0.0.0/8 - gateway IP - 10.8.2.65
[b] eth1 ISP assigned network 202.54.22.128/28 - gateway IP - 202.54.22.129
I can only ping to public server but not to another servers inside LAN? I'm not able to route traffic via 10.8.2.65. How do I configure static routing under Red Hat Enterprise Linux 5.x or CentOS Linux 5.2?
A. Under Red Hat you need to define static routing using route command. The configuration is stored under /etc/sysconfig/network-scripts/route-eth0 for eth0 interface.
Update route using route command
Type the following command:# route add -net 10.0.0.0 netmask 255.0.0.0 gw 10.8.2.65 eth0
# route -n
Create static routing file
The drawback of abive 'route' command is that, when RHEL reboots it will forget static routes. So store them in configuration file:echo '10.0.0.0/8 via 10.8.2.65' >> /etc/sysconfig/network-scripts/route-eth0
Restart networking:
# service network restart
Verify new changes:
# route -n
# ping 10.8.2.65
# ping 10.8.2.10
# ping google.com
# traceroute google.com
# traceroute 10.8.2.10
