VPN problems on ASA 5520

Hi,

i have configured a remote access VPN on my ASA 5520 with simple wizard.

From a remote client it's possible to acces to my secure network, but if the client is behind an another Cisco Firewall (PIX or ASA) isn't possible to access to my secure network.

Why?

enable NAT-T. "isakmp nat-t" on the VPN head end ASA 5520.

The reason is PAT blocks IPsec protocol i.e ESP protocol as it does not support ports.
