Snort: how to block by binder using service keyword ?

Hello, I have snort3 and I want to block telnet traffic on any port.

In wizard there are default recognition of telnet service.

But blocking using binder rule doesn't work. It is only works if I
specifies port (23).

Such config can block successfully:

binder = {}
wizard = default_wizard
binder[1] = { when = { proto="tcp",dst_ports="23", }, use = { action =
"block"}}
binder[2]={ use = { type = "telnet" }, when = { service = "telnet" } }
binder[3]={ use = { type = "wizard" } }

Such config can not block:


binder = {}
wizard = default_wizard
binder[1] = { when = { service="telnet", }, use = { action = "block"}}
binder[2]={ use = { type = "wizard" } }

Thanks for replay..
