Don’t thank me yet, I don’t know much, but I’ll try and help and am glad you’ve found a work around in the meanwhile. I don’t know much about McAfee, but then again I don’t see why it’s blocking your connection if it’s a antivirus (does it have some kind of firewall capability or something). Well you could always test by shutting down mcafee temporarily and trying the connection. Try the one without comodo first and then the comodo machine.
Okay now we have an application, can you fire up your logs (view firewall logs) and then click on more, and tell me if there are any reports for firefox?
In the meanwhile. Lets see about outgoing.
So, lets try firefox first, can you tell me what rule is currently defined for firefox in applications. Go to advanced, network security policy (did you use a custom or predefined is what I’m getting at). I usually just predefine the thing as web browser without any problems. Basically, highlight the firefox entry and hit edit.
Okay, what we’re going to do is set it to custom policy mode, and copy whatever predefined policy you have, if you’re using a predefined (In my case, I would set it to custom->copy from->predefined->web browser). Okay you’ll get a bunch of allows (greens), which aren’t really important to us at this point, but the significant ones are the blocks (red). We’re basically going to set a new allow for firefox to connect to that specific port. Click on add and you’ll get a new pop up for the specifics.
-Obviously we’ll want it to allow
-TCP or UDP if you don’t know the type, if you know the specific type then by all means define it. The stricter we can make this the better for security.
-For direction you’ll want an out
-Description you can type anything in to help remember what this is for, you can use “Cpanel” for example
-You can leave the source IP as is, since that’s going to be you because we already defined this thing as outgoing, and destination IP as is as well, unless you know how to set host names and the like (I don’t, sorry).
-Source Port, if you know the specific port this thing goes out from, by all means set a source. Destination port is 2082.
Okay now that we have this rule, you have to make sure it’s above any block rules. Comodo uses a top down approach, so in my case since I use a web browser policy there’s a block all at the end. Basically had I placed any new rule after the block all, the block all would void them. Just highlight the new rule and press move up until it clears the blocks.
