RouterOS Scripting
1

I’m using RB433AH ，Routeros Version 3.22

In order get an ipaddress connection count [include all of the port connections from the ip],


it could work in this scripting /ip firewall connection> print where src-address=“10.5.50.1:64874”

i tried in /ip firewall connection print where src=“1.2.3.0/24:0-65535”
an error comes out "invalid value for argument address "

i need to get all of the port connection from the ip!

then i searched from Google,only got the manual_2.4:
link here http://www.mikrotik.com/documentation/manual_2.4/Basic/Scripting.html
it may use in Version 2.4 " dst-address=1.2.3.0/24:0-65535"
