This wiki page states that providing alternate ports for each JBoss instance is not recommended because it "makes firewall rules too difficult to maintain". This sound like a silly reason to me. The firewall will block everything but 443 (https) and/or 80 (http). Is there another reason this isn't recommended?
I'm asking because I'm considering porting an application suite from Weblogic that runs ten applications on five servers on five different ports. Nothing reaches the application directly, everything is proxied through Apache. This architecture has worked out great. Is there any reason I won't be able to do this on JBoss.
