Cannot SSH to server over PPTP from within ISA 2004 (SBS2k3) network using firewall client??

I am on an SBS 2003 Network using ISA 2004 and my machine is using the Firewall Client.  

I recently got a virtual server at softlayer and I can open a vpn connection to the softlayer network and ping my server however I cannot connect using SSH with PuTTY.  

I can disable the firewall client temporarily and SSH to the server and then re-enable the firewall client and my SSH connection will stay up.

Does anyone have any ideas about why the firewall client / ISA Server is not allowing the SSH connection?  

Also, the ISA logs do not show any blocked connections.

Thanks in advance,

David
