network segregation of multiple instances

[simoncn]

In MinimServer 2, this is handled automatically. All instances share the same IP address and NIC. The first instance to be started gets an HTTP port of 9790 and a UPnP port of 9791. Subsequent instances get the first available HTTP port from 9792 onwards and a randomly assigned UPnP port. The display names of the subsequent instances are suffixed to make them unique.

Edit: This is not working on FreeBSD, apparently because of an ohNet limitation. On FreeBSD, port numbers of all instances must be configured manually to ensure no conflict. See this post.
