Check apf's logfile, usually in /var/log/apf_log.

Furthermore, for testing purposes, apf has a developer mode that can be 
enabled in the configfile, usually /etc/apf/conf.apf:
# [Main]
##
# !!! Do not leave set to (1) !!!
# When set to enabled; 5 minute cronjob is set to stop the firewall. Set
# this off (0) when firewall is determined to be operating as desired.
DEVEL_MODE="0"

setting devel_mode to 1 forces apf to stop (and allow all connections) 
after 5 minutes.

Kind regards
Maurice
