Block non-queued traffic

I have a queue tree setup along with the queue types, address list and mangle to throttle bandwidth to my customers. But i occasionally have the new customer come online and I forget to put them into a queue so they get access to all the bandwidth I can deliver.
Is it possible to automatically assign these folks to a lesser queue until I get a chance to assign them to their proper speed?

thanks

if you mark all customers with mangle, and those rules don’t have “passthrough”, then it’s very simple. just add one more mangle rule called “others” and don’t specify any IP or anything. This will be your last catch-all mangle rule, and you can make a special queue for that.

Never thought of that… Thanks!

also, not marked packets have ‘packet-mark=no-mark’. you can either drop that in firewall filter, or add a queue for routing mark ‘no-mark’. all this is about v4
