Can't edit Local Network field when creating OpenVPN Server config?

[axxxxe]

Total noob here.  Trying to get OpenVPN working on pfSense box.

I have a completely default config on the pfSense machine and everything seems to work so now I am trying to add a VPN Server config.  I use the web interface and click VPN > OpenVPN and then "+" and I get a web page where I can set up a Server config.

But the following 3 fields are grayed out and not editable: Use Static IPs, Local Network, and Client-to-client VPN.

I have this problem with the fields on both Safari and Firefox (I'm on a Mac running OSX 10.6.2).

?

The available options change depending on the other options chosen. You probably need to use PKI instead of Shared Key
