To improve creation of rules it is possible to make for example the following.
Add in the menu of creation of a rule for applications a line “Other” after pressing on which the window “Network Control Rule” would open and further it was possible to specify a concrete rule for applications.
again like i have said on other threads… even if you dont “have to” create advanced rules … the fact the its harder than other firewalls to do, in Comodo (not impossible, mind you) is the one Issue i have had with Comodo… I still recommend it to people all the time though
