Anyone got a working Cisco script, cisco crypto ios<–>ipsec<--->pfsense?

[rulle_mus]

Hello,
I am trying to make an ipsec tunnel with pfsense 1.2 rc4 with an Cisco 1721 with ios 12.3(crypto).
I read that people have done it, but cant find a Cisco script example. Most of the documentation is between pfsense and a pix firewall.
If anyone can post a working Cisco script i would me much obliged  ;)
Regards,
Mus
