[Pacemaker] Configuring cluster with ports

[David McCurley]

Okay, so assuming the VIP travels with the active server, one idea would be to have an iptables rule on each server that does a local redirect:

On the 8081 machine:

iptables -t nat -I PREROUTING --source 0/0 --destination 0/0 -p tcp --dport 8080 -j REDIRECT --to-ports 8081

And on the 8082 machine:

iptables -t nat -I PREROUTING --source 0/0 --destination 0/0 -p tcp --dport 8080 -j REDIRECT --to-ports 8082

Hello the list, 

I have to make a cluster with two servers, having the architecture in the image bellow 



The two severs share a virtual IP (VIP), and when we call the VIP in port 8080 VIP:8080, it must be redirected to the first server (if active) on port 8081 or to the second (if active) on port 8082 (IP1:8081 or IP2:8082). 
How is it possible to tell pacemaker the ports that we need to redirect the request to. 

Thanks in advance. 
Regards
