PIX 501 VPN Configuration

I have 3 PIX 501 firewalls running PPOE ADSL connections.

Head Office

2 * Remote locations

We need to extend the configuration to include some VPN features:

Office PAT (I think this is the term) - external inbound connections (eg port

80 443 5060 etc) - WORKING Software VPNClient will connect to this point (users travelling need to access the office network) - WORKING Hardware VPN Host (Server) Radius SERVER authentication for software VPN clients - WORKING Provides primary internet connection for this location

Remote1 PAT (I think this is the term) - external inbound connections (eg port

80 443 5060 etc) - WORKING Software VPNClient will connect to this point (users travelling need to access the office network) Hardware VPN will connect to Office - needs to be in NEM mode - both sides should be able to see resources on both sides Provides primary internet connection for this location - this means we need split tunnel for the VPN connection??? How does DHCP work with with a hardware VPN, should we have a local DHCP or does it get addresses from the HEAD OFFICE?

Remote2 Software VPNClient will connect to this point (I believe that users in remote1 location would need to do this to access resources in this location?) Hardware VPN will connect to Office - needs to be in NEM mode - both sides should be able to see resources on both sides No external internet access required here

Is this possible? I have read a range of materials much of which is confusing for the inexperienced. Some of the items concerning me are

PAT cant be done whilst the Hardware vpn is configured? Software and Hardware VPN hosts (servers) cant coexist on same device Remote1 cant route to Remote2 (in out not allowed rule on one interface???) This relates to my DHCP question I think.

Where do I go to start to get a working config for this?

At the moment I have PPOE connection going ok and the inbound PAT stuff working with software VPN authenticating against a separate RADIUS server.

Thanks
