VPN Across Two Routers

My client wants to establish a VPN connection so that he can access his office Win XP machine from his home Win XP machine.  The problem is that his office is behind two routers - his own on a 192.168.15.x network and the main router for the office complex on a 192.168.1.x network.

I have spoken to the engineers who manage the office complex router and they say it can be done as long as we use a non-standard port.  However I can't see an option in Win XP to use a non-standard port for PPTP, either for the VPN host or the VPN client.

Any thoughts on this, please?

I don't think you will get this to work with a Windows VPN as the 2 routers are performing NAT (Network Address Translation).
Also you cannot change the default PPTP port as you can for some other services.
You might have better luck using a 3rd party tool such as  http://www.logmein.com  or their VPN utility Hamachi which requires not router configuration;  http://www.hamachi.cc

Why is he behind his own router? I assume because of this, he does not have access to the other systems on the 192.168.1.x subnet. If so and you want to pursue the original idea, will the managers of the building router be willing to put his router in the DMZ zone of the primary router ? I have seen this work in some configurations, but his only source of protection from the outside world will be his own router.

Keep in mind the home site cannot use 192.168.1.x or 192.168.15.x

Thanks, I'll check out those third party solutions.  The office complex comprises office space sublet to a number of small businesses ,each with their own local network.
