I'm trying to get Acquisition (Mac OS X) to open it's ports (6346, 6881) at the router. I've set a unique port opening in the Mac OS X firewall, as instructed at http://www.acquisitionx.com/ports.php. I then log-in to the router (192.168.1.1) and set UPnP to "enable." Now I'm stuck. Acquisition will connect, find a query, but not allow me to download a file. It's preference...network is set to the same ports for TCP (6346) and DUP (6881) but it tells me "router ports need to be configured." I'm a lifetime registered user and the author of the software has not yet responded (even though he advertises a response will be sent to registered users). While I wait, I stumbled on this forum and am asking for help. Has anyone else dealt with port mapping issues? I really don't want to try DMZ "enabled" and I have tried specifying the ports in port forwarding and port triggering, but this doesn't appear to work. Am I dealing with one of those crappy versions of the WRT54G v5? (I did update it's FW through the web admin from 1.00.0 to 1.02.0, the latest I could find of official FW updates.) Any help is much appreciated.
