Map webdispatcher http port to specific IP address

Hello,

I have a W2k3 system with 2 public ips 1.1.1.10 and 1.1.1.20

It is connected to a hw load balancer.

This setup is for test puposses.

The load balancer balances over these 2 ips .10 and .20

I have installed 2 Webdispachters 7.0

I want 1 webdispatcher to listen to ip .10 and the other to listen to ip .20

I have created entries in the hosts file to that .10 resolves to web111 and .20 to web1112

I have added the entry icm/host_name_full to the instance profile

but, it doesnt work

is there another way?

thanks

sander
