Sorry for the generic description in the subject, but it would too much time to make a topic + subject for every issue:
-
CFP breaks uPnP. You can add custom rules to allow uPnP traffic, but something like uPnP should be defined by default as a firewall rule and should be easily turned on/off.
-
incomplete listing of predefined ports:
* email ports are missing 587 (SMTP MSA), 995 (POP3-SSL) and 996 (IMAP-SSL)- web ports are missing 8080 (proxy) or non-default (but used) ports like 81.
- no predefined ports for IRC/BitTorrent/UPnP/SSH/IM/SNMP
-
No option to use a firewall event to define a custom rule
-
CFP keeps submitting the same files to Comodo after doing a lookup though Proactive Defense / Review. Hence it alse pop-ups the very same error (cannot submit file…) once in a while.
-
Unable to use SHIFT to select multiple files at once in Proactive Defense > Review Pending Files
-
ICMP Filtering though Global Rules is way too limited. No option to block specific ICMP subtypes or use ICMP’s by their number/subtype-number.
-
Defense+ popup (e.g. Defense+ is learning…) in lower left corner of the screen blocks the answer buttons of other Comodo dialogue boxes.
-
No automatic popup to add Trusted Software Vendors when an application launches which is signed with a Code Signing Certificate.
-
CFP does not recognize “My Network Zone” (e.g. 192.168.1.0/255.255.255.0) as a private/trusted network: Printing to a shared printer pop-ups a dialogue box saying an application is trying to connect to the internet, even though the IP is local (192.168.1.100, which is most definitely, not the internet) and within my network zone
-
No option to update to beta / RC versions using the build-in updater
Apart from these, the UI of Comodo looks very good, is functional and allows easy access to all options once you’re used to them. The Purge button is excellent and is something I’ve been missing in a lot of other apps (e.g. NOD32 for example). Overall, is seems like an excellent firewall which just need a bit of polishing here and there. (B)
