i have two web servers hosting the same site installed behind a zentyal server cum firewall (which i installed and configured with mod_proxy module (thanks to google ) i can reach both servers from internet however as already discussed, there is no load balancing on servers. From somewhere i came to know that apache module of the zentyal server also suports mod_proxy_balancer module which does the task of balancing traffic between two servers. Here goes the IP configuration of the three servers (zentyal firewall + two webservers behind zentyal). zentyal server interfaces (theree in total) eth1 (WAN): 115.xx.xx.18 eth2 (WAN): 115.xx.xx.19 eth0 (LAN): 192.168.10.1 web serverA (connected to zentyal LAN interface): 192.168.10.2 web serverB (also connected to zentyal): 192.168.10.3. Thanks in advance!!!
