This is a modernization effort on https://forum.pfsense.org/index.php?topic=115672.0
The list of dependencies has grown somewhat. Browsing through http://pkg.freebsd.org/FreeBSD:11:amd64/release_1/All/
you will need to pkg add http://pkg.freebsd.org/FreeBSD:11:amd64/release_1/All/...
the following:
- openconnect-7.08.txz
- vpnc-scripts-20161215.txz
If you want the qt-based desktop GUI, you will also need these (and probably others):
- libtasn1-4.12.txz
- p11-kit-0.23.7.txz
- tpm-emulator-0.7.4_2.txz
- trousers-0.3.14_1.txz
- gnutls-3.5.13.txz
- qt5-concurrent-5.7.1.txz
- openconnect-gui-1.4.1.txz
