Change web portal services IP Address

Hi All.. i have some doubts about ECS network separation.

I had installed the ECS 3.1 (community edition) with the IP Adress x.x.x.x and all services are listening in that IP (has logic). Now.. i've added a new interface with the IP z.z.z.z   ...Its possible to change the web portal listening address from x.x.x.x to z.z.z.z??. sre

Now all services are OK in the x.x.x.x but i want to access tothe ECS Web Portal via another IP Address.
