Currently, only ports below 49152 are accepted, otherwise, Glowstone falls back to 25565. This produces this warning:
20:08:46 [WARNING] Invalid config value for 'server.port' (54224), resetting to default (25565)
While the ports 49152 to 65535 are considered private/dynamic ports and probably aren't ideal to use under many circumstances, they are still valid ports and should be accepted by Glowstone.
At Aternos, we use a large port range including that private range to reduce the chance of conflicting ports while trying to keep the server port consistent for the user.
(Same as #1126 but for the 1.12 branch)
