Creating port-alias fails

[dan_m_joh]

Hello,

I am new to OPNsense and are trying to setup some Firewall rules using aliases.
But when I try to create an alias for "rsync" I get the followingf error message "Reserved protocol or service names may not be used".
OK, I thought - rsync is already defined as a service...

BUT, when I try to use "rsync" while creating a new rule I get the message "Please specify a valid portnumber, name, alias or range." when I enter "rsync" for "Single port or range".
"rsync/RSYNC" is not present in the drop-down-list for Destination Port.
The same goes for other ports as well, for instance "git".

Am I completely missing/misunderstanding something or is this some bug?

Regards,
Dan
