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?

I am running the "OPNsense 26.1.6-amd64" version at the moment (updated this morning).

Regards,
Dan

try with a name other than a recognised service i.e. myrsync instead of rsync - as the message suggests.
It seems it is not that it already has a deifinition for it that you can select from the drop-down but as a reserved name.

I use semantic naming of all my aliases:

- Port_foo
- Host4_foo
- Host6_foo
- Net4_foo
- Net6_foo
- List_foo
- Group_foo

Maybe you'll like that, too.
