I don't have a dust collector hence, use a shop vac & tubing system to collect cuttings from my various machines. With limited dust collecting ability with this system I have found that collection as close to the source as possible does offset a good part of the lack of larger air volumes with high air velocity instead.
I have a vac connection at the fence as well as at a air chamber mounted on the router itself between the motor and base. I have been using this system for probably 8 years at least & does a pretty good job.

You will notice that the vacuum port is in direct line of the bit cuttings discharge.
