Is there a difference between Inbound/Outbound connections via the main interface vs Incoming/Outgoing connections via Firewall Application Rules? Any program that I add or has been put in the Firewall Application Rules are set to Outbound and that seems to work just fine, but in what instance would you want to allow both incoming and outgoing connections?

Inbound: traffic initiate from external.
Outbound: traffic initiate from internal.
As for Inbound vs Incoming, Outbound vs Outgoing, I think there are no difference and is a matter of wording only.
As mmalheiros has pointed out, the terms “inbound/outbound” and “incoming/outgoing” mean exactly the same thing.

Inbound connections are used when another system needs to contact your system - like if you were running a games server (or a web server, or an FTP server) and your friends want to connect to your server. Ordinarily, Comodo will block all unsolicited inbound requests unless there is a global or application firewall rule specifically allowing the traffic.

Yes, thank you. That helps immensely.
Is there any way to Enable Cloud Based Analysis of Files if you didn’t enable it when installing Comodo Firewall? I’m trying to submit an unrecognized file, but I’m receiving the following error: “0x80072f8f content decoding has failed”
Pretty sure this will do it.
- Open CIS
- Click SETTINGS
- In the SETTINGS window, click FILE RATING → FILE RATING SETTINGS
- Enable the first 3 options and click OK.
Hope this helps,
