All the connections, from how many clients?
You might be better off using LVS for this.

Hi guys, I need some help on configuring NLB for my application
servers. I've installed tomcat on 4 servers and I've decided to use
Linux HA for Network Load Balancing, but is seems like all the
connections are going only to one of the servers (app-node-1). Can
someone tell me what I'm doing wrong? It's pretty simple config, just
one clone resource (IPaddr2) running on all nodes. Also, can someone
tell me how is NLB done? based on source IP, IP hash or... I need
Round Robbin NLB.
