It is much easier to help when you provide the configuration that you have applied. Also be very clear in explaining what you want to achieve. If using the GUI, their is an option to display the text. Please copy and pastre it in the comments.
So you want to all traffic to
allow destination port 445 for Source= IP 10.255.1.1/32
block destination port 445 for Source= IP all others
allow all other traffic for all devices
[edit firewall family ethernet-switching filter block-dest-port-445]
set term accept-IP from destination-port 445
set term accept-IP from protocol tcp
set term accept-IP from source-address 10.255.1.1/32
set term accept-IP then accept
set term block-IP from destination-port 445
set term block-IP from protocol tcp
set term block-IP from source-address 0/0
set term block-IP then discard
set term accept-all-IP then accept
top set vlans <vlan_name> filter input block-dest-port-445
Remember these are one way filters. If you want to regulate traffic in the opposite direction you need to create another using destination-address and apply it as an output filter on the said vlan(s)
