ipsec puzzle on cisco 1811

I have a cage containing "V" (Windows XP) and "R/S" (Cisco 1811 Router+Switch). V needs to talk (via R/S) to a service on port 6910 of "P", which is outside the cage.

P talks IPSec for port 6910 traffic.

I am handcuffed, I cannot change config of P or config of V. So I need to use R/S to gateway the IPSec. I will be happy if R/S does IPSec for traffic to port 6910 at any address external to the cage.

Is this problem going to have a solution?

Your first question might be "what is the config at P?". I don't know how to answer that directly, but I have provided all info about a Windows secpol that successfully talks to P, which should yield the P config, right?

For more complete problem description including beautiful diagrams and an equivalent security policy on Windows that I'm trying to mimic, please see

Thanks for any guidance.
