nat port 500/udp and 4500 /udp

Hi Folks, I have a linksys ag241v2 and a wag325n. I need to know how to nat 500/udp and 4500/udp packets from the hosts (windows xp) connected to these systems. I have disabled ipsec passthrough because windows xp support nat-t. When the windows xp box send the ike packets I don't see nothing on the other side. Any hint? PS: the am200 modem is working good out of the box.

I have an ipsec vpn software running on windows xp. Ipsec behind nat need port 500/udp for ike and 4500/udp for incapsulating esp datagram to udp datagram. These two devices (wag325n anf ag241v2) drop these packets.
