Use CentOS Linux for Routing, Proxy, NAT, DHCP – Part 9

In part 9, I show how to manually configure a single network interface into multiple subinterfaces in order to support VLANs and Trunking. The network VLAN interfaces are configured in CentOS Linux with ip addresses, gateway address, and DNS. The configurations are saved the so they can be automatically loaded on restart.

In this series of tutorials we convert a CentOS server to a transparent proxy that can handle routing, network address translation (NAT), DHCP, and DNS.
