Hi all, I have a Linux Server that I've managed to setup using the CentOS perfect guide. It has two NICs each one with a public static IP address but it's outside my network and when I'm developing a web site, I have lots of waiting times each time a file is compared, uploaded or downloaded. Is there any way of "sharing" the server between my LAN using one NIC and the outside world using the second NIC? For example, tell my FTP program to connect to http://192.168.0.100 (LAN address) but have the possibility to see the websites from the outside using either an IP address or domain name? I've done it before with Windows Servers and I think it's very doable with Linux... just don't know how. BTW all my sites are backed up so I don't mind formatting and installing the server all over again. Thanks!
Hi You can do this by configure your network interfaces manually without a gateway on the lan interface. I am no centos expert but it must be something like this. 1. Set up WAN NIC. edit /etc/sysconfig/network-scripts/ifcfg-eth0 should looks like: DEVICE=eth0 ONBOOT=yes BOOTPROTO=static IPADDR=aa.aa.aa.aa # e.g. 123.45.67.89 NETMASK=bb.bb.bb.bb # e.g. 255.255.255.0 GATEWAY=ee.ee.ee.ee # e.g. 123.45.67.1 TYPE=Ethernet Set up LAN NIC. This step requires operations similar to previous step. Edit /etc/sysconfig/network-scripts/ifcfg-eth1 and make sure that it looks like: DEVICE=eth1 ONBOOT=yes BOOTPROTO=static IPADDR=cc.cc.cc.cc # e.g. 192.168.0.100 NETMASK=dd.dd.dd.dd # e.g. 255.255.255.0 NETWORK=192.168.0.0 BROADCAST=192.168.0.255 TYPE=Ethernet Afterwards you have to restart the network: /etc/init.d/network restart check your config ifconfig
