Hi, I wasn't sure what category to put this under, so I went with ISPConfig to get the proper set-up instructions. This is what I am trying to do. I have a new Linux server set-up with a single public ip, netmask, gateway, etc. all configured already. I know now that this is going to cause bad load balancing issues soon so I have purchased a combination load balancer / port forwarding router to prevent this. When setting it up, I made adjustments to system-config-network, set up the LAN ip 192.168.x.xx as the first IP. I would like a step-by-step guide (please) to set this up without wrecking ISPConfig 3.0.4. My plan was to then create multiple static ips like my first box is now using: eth0 eth0:0 eth0:1 etc., etc, I also want to know (because I have this option) if I should add an additional ethernet card as eth1 and put the load balancer / router on this. I have seen that this can be done, but NOT in relation to ISPConfig, which is the deciding factor, as this is the CPanel I will be using. (already set-up flawlessly) Thanks in advance!
Hi - not sure if this will help since my setup is different to yours but this is what I do: Configure the main server with the static IP (as you have already done so far as I can tell) your network interfaces would look something like this: # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet static address 192.168.1.200 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.1 install bridge-utils edit your "interfaces" file to look something like this: # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary network interface # auto eth0 # iface eth0 inet dhcp # br0 auto br0 iface br0 inet static address 192.168.1.200 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.1 bridge_ports eth0 bridge_fd 0 bridge_maxwait 0 bridge_stp off post-up /usr/sbin/brctl setfd br0 0 Then your new servers (or virtual machines) can all be configured with their own eth0 interfaces and be able to talk to each other. OR set a few bridges up to isolate services and domain names (I don't have this setup at the moment but have used it before): # br0 auto br0 iface br0 inet static address 192.168.1.200 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.1 bridge_ports eth0 bridge_fd 0 bridge_maxwait 0 bridge_stp off post-up /usr/sbin/brctl setfd br0 0 # br1 auto br0 iface br0 inet static address 192.168.1.201 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.1 bridge_ports eth0 (or bridge to an eth1 interfaces) bridge_fd 0 bridge_maxwait 0 bridge_stp off post-up /usr/sbin/brctl setfd br1 0 As you can see there are quite a few ways to set up networking. Good luck
