[isalist] TMG and outbound PPTP

Hello,

I have a strange issue in allowing outbound PPTP using TMG (SP1).
I want to allow outbound PPTP connections from a segment where clients are
SecureNet clients and a NAT relationship exists between the segment and the
external interface.

I noticed connections are working fine only:
- if VPN Client access on the TMG is disabled
OR
- if VPN client access is enabled and PPTP vpn access is checked in the VPN
Client Properties > Protocols tab.
In each other case, the clients gets stuck on the 'Verifying username and
password' dialog box and eventually times out with error 619.

Note I don't want to set up a vpn towards the TMG server, only allow
outbound PPTP connections.
I remember a setting 'Enable IP Routing' in ISA 2006 which was required for
outbound PPTP but can't find this anymore within TMG.

Anyone noticed the same behavior or any explanation for this?

Thanks,
Wim
