Site to site ipsec tunnel with ipsc/l2tp

[Aderium]

Hi there,
Our main site uses PF Sense Beta 1 with IPSEC VPN enabledfor tunneling to the branches.
One of our branches (very small one) has a mac mini with Mac OS X Server 10.4.4 as its main router and firewall.
is it possible to create a tunnel from branch one knowing that the mac mini allowes for VPN ipsec/l2tp ?
os x has a s2svpnadmin cli bin to generate the tunnel and uses racoon

Thanks

Anthony
