I know I wrote a good review of this product. I tried to do a simple port based vlan to share printers between 2 small companies.
it was a nightmare, didn’t work at all on watchguard it would have been a 30 mins job.
with draytek support ask me to update firmware still no luck then they send me a beta firmware still the same issue.
only way I fixed it with beta firmware and factory reset the device and put all the setting backup on which worked. but took long time
I wouldn’t recommend this if you thinking to do VLAN etc
