i am working on a version of winbox for windows mobile and haven’t been able to find a way to list routing mark, connection marks, etc that are currently registered with ros. hope someone can help.
currently there is no straight forward way how to get that information like available routing-marks, connection-marks, firewall chains etc.
Just like Janis said, there is no “easy” way. You could print a list of existing rules, and parse that list to get a list of used marks.
We will make some better way for the API 
thank you, thats what i needed. i will do it that way until the api has been updated.
