Publishing is limited to the NAT-able protocols; TCP and UDP. GRE isn't one
of those.
PPTP from behind ISA is available only to secureNAT clients and only via a
PPTP packet filter AND the "Allow PPTP for secureNAT clients" setting in IP
Packet Filtering properties.
This is outbound-only traffic that ISA handles internally.

ISA can't publish PPTP for that reason but can you open up an internal VPN
server via packet filters?
