IPSec Problem over Router

[red temptation <red_temptation2003 () yahoo de>]

hi,

we have a Problem concerning IPSec. We want to create
a tunnel from a WinXP Laptop (located on the Internet
with an official IP), to a private Network (using
NAT). For authentication purpose we use certificates.

It's no problem to open Port 500 on our current
Network-Router, but Protocol 50 and 51 are not
supported while using NAT. That's why we are not able
to establish an IPSec tunnel with that router.

Can anyone suggest a low cost Router with the ability
to store certificates and enable us to establish the
tunnel. It should have an included firewall.

regards,
