Sounds like a classic example of a firewall or NAT box breaking PPTP. 
I'd try with a public IP directly on the system, like use a dial up
account or something if you have to.  If that works, fix the firewall
at work.  Most every firewall/NAT box can be configured so it will
pass through PPTP without destroying it.
