LoL .exe files and firewall

Hi! I've had laggy client for the longest time and i've found a solution for me. I've added LoL client .exe and actual game .exe file into my firewall. I had the whole league of legends directory included as an exception before and seems it didn't work lol. So i have a question: do i need to re-include this .exe files after every patch, because i've included only the latest releases? Thx in advance :)
