For those that are concerend with the impact on your existing services, you are overlooking the easy solution. In the case in point here, it is a home network, which means you have an abunance of IP address at your dispossal. If you want to keep everything seperated, assign a virtual IP to that server, thus giving it two listening addresses, and bind all the Zimbra services to your newly added VIP.
I guess the point is, when you read the documentation, it states that Apache, MySQL, etc... are going to be installed. Let's just assume they are going to use default ports for these, thus we know we are going to run into conflicts. Leave your current configuration bound to "localhost" and bind everything else to a secondary IP address. One server, two functions. |
