Setup static routes for IP address in CentOS
Posted on 2016-08-15
I have a CentOS VM that has two network interfaces. One interface is connected to our "public lan" that that the other Windows servers and end users are on. The other interface is connected to our "private lan" which is a closed network that the SAN, ESXi hosts, and a few other systems reside. I have to set the CentOS server up this way since our DR backup solution will be maintained by this CentOS server and it will need access to both networks. One to access the internet so it can send the data to the cloud and the other to allow communication with the hosts so it can grab the vmdk files for backup. Both NICs use 192.168.3.x except the Private lan does not use a gateway since there is no reason. What I need to do is point specific 192.168.3 IPs to use the Public interface and other 192.168.3 IPs to use the Private. Below is the ranges I need on each interface.
192.168.3.2-15 and .66-254
If anyone can provide assistance it would be appreciated. Thanks
