Weve a web application that uses Apache (Port 80) for load distribution along 4 Tomcat's (HTTP Ports 8080, 9080, 10080 and 11080). So, when one user enters the page, Apache redirects it to one of the Tomcats in order (Round Robin Algorithm). Anyway, this redirection works well if the user is not behind a Firewall. However, if the user is behind a Firewall we have two cases:
1) If the user enters www.mypage.com he will get an error page because the redirection wont work.
2) Assume that www.mypage.com has the IP 200.93.xxx.xx if the user is behind the firewall and he enters 200.93.xxx.xx the redirection works well.
Any idea of why does this happens?
How can we solve it?
