FWSM GRE/PPTP tunnel

Hi,

has anyone tried to implement a GRE/PPTP tunnel over the FWSM (tunnel has to cross the firewall, it will be terminated internally)

Here is a doc http://www.ciscotaccc.com/kaidara-advisor/security/showcase?case=K04129020

but it seems to be Release dependent. On a old release it is working, with a newer one I get the error "unknown IP protocol 47".

Any hints
