Hi I'm setting up pfsense with squid3 and dansguardian packages. When I try to start the dansguardian service however, I get the following errors:

May 27 22:17:37 php: /pkg_edit.php: The command '/usr/local/etc/rc.d/dansguardian.sh start' returned exit code '1', the output was 'kern.ipc.somaxconn: 16384 -> 16384 kern.maxfiles: 131072 -> 131072 kern.maxfilesperproc: 104856 -> 104856 kern.threads.max_threads_per_proc: 4096 -> 4096 Starting dansguardian. filterports (2) must match number of filterips (1) Error parsing the dansguardian.conf file or other DansGuardian configuration files /usr/local/etc/rc.d/dansguardian.sh: WARNING: failed to start dansguardian'

What does "filterports must match number of filterips" mean? Any thoughts on the matter?
