OpenVPN should work, as long as its standard UDP Port (1194) ist properly redirected to the pfSense box behind the Cisco. The other pfsense on the ADSL (I assume) line should work just fine. Anything further depends on the ip/netmasks used on either side and the mode used for openvpn. But at a first glance I can't see anything that should spoil the fun here - as long as the cisco is fowarding the openvpn-udp packets adressed for the public ip to the pfsense on its transfer-net (wan)

This is going to sound dumb, but just reload.  Seriously. I've had this bug occur on firefox on various platforms depending on what extensions I have installed.  Reload, disable NoScript, whitelist the site in Adblock, do whatever you have to do to make sure javascript executes, etc etc etc. It'll come back.  If not, try leaving some cat food out on the front porch.  Maybe it'll find it's way home then.  ;D

there are also route-up and route-down, plus just plain route statments that can be placed into your server config.  ;D Please look more carefully at the examples.  You'll be amazed at how customized openvpn can get.
