virtual pool

Thanks Kevin. What if I need to assign\open additional ports for those nodes, do I create a new virtual pool and add those nodes under it as well with the new port number(s), say https? In other words, say I have two nodes part of a pool and they only need to listen on port 80, I will put both of them together under 1 virtual pool. What if one of the nodes (pool members) now needs to listen on port 443, do I create a new virtual pool that listens only on that port and add that node? So what happens down the line when I need to add more nodes? Is it best practice or not to create virtual pools with members that listen only on the same port? So if I only care about port 80, port 443 and port 5050 would I then create 3 virtual pools and add whatever members to those respective pools?
