Ubuntu 12.04 Load balancer

Question

I am looking to create a load balancing server. Essentially here is what I want to do:

I have a public IP address, lets say 1.1.1.1 I have a second public IP address, lets say 2.2.2.2

Here is what I want to happen. I have a website, www.f.com point to 1.1.1.1 via an A record. I want that Ubuntu server to forward traffic appropriately.

• Port 80 traffic is forwarded to 2.2.2.2 on port 60,000 and port 60,001.

• Port 443 traffic is forwaded to 2.2.2.2 on port 60,010 and port 60,011.

• Port 25 traffic is forwared to 2.2.2.2 on port 60,020 and port 60,021

The port forwarding from port to port is more important then being able to load balance.

I look forward to some responses. Both server 1.1.1.1 and 2.2.2.2 are both running Ubuntu 12.04 server edition.

Answer 1

I would recommend Pound (http://www.apsis.ch/pound). It's lightweight, easy to configure, handles https quick and efficient, and does exactly what you want.

Answer 2

With a combination of iptables rules you will be able to achieve load balancing using the examples at this link

There are some pretty good examples that you will be able to follow. My experience with advanced iptables configurations is limited, but that link should point you in the right direction
