I have forwarded port 1723 from modem to router and i used to work
with it just fine, therefore virtual servers are set OK.

However my problem is this...how can I forward the 1723 port to my
virtual machine? should I use the public IP address of the host OS or
of the virtual machine? I tried both but with no luck and I guess I
am missing something here...

Forward from the VM's public IP to the internal host.

If you want to port forward PPTP VPN traffic, you need to forward TCP 1723 as well as GRE or Protocol ID 47.

If you want to port forward IPSec/L2TP traffic, you have to forward multiple ports. Theres's two parts of it, the L2TP traffic uses UDP Port 1701, and the IPSec traffic requires the following: UDP Port 500, Protocol ID 50 and Protocol ID 51.

Note: Protocol ID numbers are NOT port numbers.

You didn't mention which operating system the VM is. Assuming Windows 2003, it should have the options to forward Protocol ID#s. It's easy in the major firewalls, too. Other low-end DSL/Cable/NAT routers may be difficult, depending on the brand.
