I have been using APF for a while now and recently I have been having a lot of problems with it locking out either random ports or all of them at about 4am (same time as upcp is run) I have tried to fix this problem but nothing seems to work. It is definatly a firewall issue because if I connect with SSH before the ports get blocked I can just restart APF and everything works fine again. If anyone has any suggestions of what I could look at to solve this then I would be very grateful. getting up at 4am everyday to check on the server is no fun! Also alternatives to APF would be good to know aswell.
