does PS3Xploit 4.84 HFW work offline?

i know PS3Xploit 4.84 HFW requires an active internet connection and an active PSN account for first time installation, but once the HFW is installed, do you still need to maintain an active internet connection for the HFW to work? will i break the HFW exploit by disconnecting the ps3 console from the internet?

also will my psn account be banned if i keep the ps3 console connected to the internet with HFW installed?


thanks for letting me know!
