Have a look into Hamachi

Zero config. Depending on who the IPs have to appear different to, it may
suit your need, or it may just help you tunnel out.

Otherwise, I own an IPBlock with 5 IPs. if this isn't enterprizey, and you
have a daemon that can run on windows, I may be able to provide you with a
jump point.
