If you read my post you would know what's wrong with passive DCC. It will only help you if the other user has configured DCC. If the other user is like you and using passive DCC, or thinks that configuring their firewall is unimportant, you will be unable to send/receive with them. If this is what you consider "working", so be it; but realize that configuring your router properly will allow DCC to work 100% of the time, using passive DCC will not.
