How to install other FreeBSD packages / repositories?
1. Make sure “enabled” key is set to “yes” in /etc/pkg/FreeBSD.conf
2. Change “enabled: no” to “enabled: yes” in /usr/local/etc/pkg/repos/FreeBSD.conf
3. Change “enabled: no” to “enabled: yes” in /usr/local/etc/pkg/repos/pfSense.conf for FreeBSD repo
4. Now you’re able to install packages from FreeBSD official repo

偵測後的結果，可根據 Primary log 解讀，方式如下：
“Open” = Open Internet
“Independent Mapping, Independent Filter” = Full Cone NAT
“Independedt Mapping, Address Dependendent Filter” = Restricted Core NAT
“Indepndent Mapping, Port Dependent Filter” = Port Restricted Core NAT
“Dependent Mapping” = Symmetric NAT
“Firewall” = Symmetric Firewall
“Blocked or could not reach STUN server” = UDP Blocked
