My Mikrotik RouterBOARD RB750 is running as Hotspot firewall,
now my problem is that i want to generate webproxy logs with user MAC address and save it to a usb disk i.e a pendrive.
I have the way to save it to a remote location i.e a computer, but i dont want to involve any computer for saving logs.

is there any way to generate and store webproxy logs (i.e which MAC address visited which web site) along with MAC address to a usb disk?
