PPTP/IPSec through a Cisco 2501

Anyone able to tell me if its possible to get PPTP/IPSec pass-through through a cisco router (specifically a Cisco 2501 -- IOS 12.0(5)T), that has an older IOS version, and therefore doesn't supprt GRE.

I can't flash it... so im hoping i can get around it another way...

Not if you are using NAPT (i.e. using the interface as the NAT address for everyone)
Yes, if using 1-1 static NAT
Yes, if not using NAT at all
