Can't PPTP out of network with ISA and ASA

I have a network configuration with two firewalls. ASA5510 is the first level of security and then Microsoft ISA is the next level of security before traffic enters the LAN. The problem I am faced with is that PPTP works inbound to the LAN but would not work on the outbound. I tried turning off the inspection but this doesn't help. I temporary replaced the ASA5510 with a 2821 router configured as a firewall and this works perfectly. Can anyone tell me why the ASA5510 would not allow the outbound PPTP connection. It works ok if the ASA5510 is standalone.

These are inbound to the network, these are working fine. The problem is that I am unable to pptp from inside the network to any host outside.
