Can't find my Canon MG5450 printer on my network

[AirFrance 0]

Hello,

 

Here's my problem : i'm trying to install my Canon MG5450 but the Network Tool can't find the printer when I use AirVPN. It does when I quit AirVPN and I tried to install the printer without AirVPN activated and it worked but the printer couldn't print anything still...

Is it a firewall problem or something ? Because it was working just fine before installing AirVPN, but I had to re-install my computer and it hasn't been working since this day.

 

Thank you for your help,
