pfSense

related to some degree to bug 8409, i've found that i'm unable to create aliases for registered services using their actual name - for example, mdns [udp/5353]. this led me to expect that, when creating a firewall rule, i would be able to use the symbolic name for this service [e.g. "mdns"], rather than having to use the port number integer ["e.g. "5353"]. however, this does not appear to work. pfsense doesn't complain, but ignores what has been provided and sets the port field to "any".

if registered services cannot be defined using aliases, then their existing symbolic names from the services(5) database should be available for use to me it would make sense to use the autocomplete mechanism for this, since inclusion in the port drop down would be impractical].

conversely, if registered services cannot be referenced by symbolic name, then an admin should be able to define an alias for a given service.
