I have CentOS 4 running on an old (early model) p3 with 64 MB RAM. It is acting as a router and firewall for my LAN.
CentOS is doing a really good job with Shorewall + DHCPd - on a 10 Mbps cable modem, I see ~ 9.7 Mbps of throughput even when numerous tcp streams to different LAN hosts are running.
I would like to add a virtual interface to one of my LAN interfaces.
My LAN interface (/etc/sysconfig/network-scripts/ifcfg-eth2) looks like:
DEVICE=eth2 BOOTPROTO=static BROADCAST=192.168.10.255 HWADDR=00:60:08:C3:F9:71 IPADDR=192.168.10.1 NETMASK=255.255.255.0 NETWORK=192.168.10.0 ONBOOT=yes TYPE=Ethernet
would adding the below:
/etc/sysconfig/network-scripts/ifcfg-eth2:0
DEVICE=eth2:0 BOOTPROTO=static BROADCAST=192.168.20.255 HWADDR=00:60:08:C3:F9:71 IPADDR=192.168.20.1 NETMASK=255.255.255.0 NETWORK=192.168.20.0 ONBOOT=yes TYPE=Ethernet
Would this create a virtual interface eth0:0 with the IP address 192.168.20.1?
Thanks in advance.
