Problem with H100 and Canon mutifunction

fabiocavallo_65

Good morning Canon asks me to perform a communication test to its
servers using port 443 and listing a series of sites (see attachment). I
tried to create a funnel with a virtal server to port 443 but the MFP
does not communicate. Canon recommends creating a white list on the
firewall but I can't find a match within the H100 management. Can you
help me thank you

Hi @fabiocavallo_65 ,

To better assist you, could you please share the following:

• The complete network topology
• The exact task you'd like to perform between your printer and the Canon server

Note: It is unable to view/ download your pdf file.

I have taken note of your answer: in the next few days I will produce
what is requested. I'm sorry that you were not able to read the pdf I
had sent that clarified the problem and tried to send it in another
format. Thank you

Hi @fabiocavallo_65,
I've read the guide (I'm Italian) but the guide suggest to open the 443 port on some FQDN addresses, but you need to do this, only if there are specific policy rules in your firewall that allow or deny direct browsing on the internet (For example, you don't want your computer to reach certain specific internet addresses, or you want to allow that printer to reach only certain addresses)

Is your printer in a network with a specific policy rules that deny internet for some reason?
In this case, what I would do is:

• Create FQDN addresses for every site;
• Create an address group that group all of these FQDN address;
• Create a custom policy rule:
  • From: Printer LAN interface
  • To: WAN
  • Source: The printer IP —> the printer needs to be in a static DHCP or fixed IP mode
  • Destination: The address group created
  • Rule: Allow

But… if your printer is in an interface that not have any specific policy rule, probably your printer is configured correctly.

I put here the original link to the guide, for any other users:
