Cisco IOS - Destination NAT within VPN tunnel to PIX/ASA

Hi,

I am trying to configure a remote worker setup where users can be given a router which they connect to their home DSL network, which will then get an address by DHCP from their router and then create a point to point VPN back to an ASA or PIX at the HQ office. This is made more complex by the fact that the HQ LAN uses 192.168.1.0/24, as do most home DSL routers. The home worker router also needs to do DHCP on its internal interfaces and dynamic NAT, so that internal machines can still access the Internet outside of the tunnel.

The network map looks like this:

I have sucessfully set up a dynamic VPN on the HQ PIX which allows the router to create a tunnel, and this works fine when connected to a DSL router with internal address range of 192.168.100.0/24, i.e. not overlapping with the HQ LAN.

I assume I need to do destination NAT on the home worker router and un-NAT on the PIX, but I cannot work out how to do this.

Any help appreciated, many thanks in advance

George
