I have a site that I need to install a Cisco 2800 router and an ASA 5510 with the AIP-10 SSM.  I would like the router to do NAT as well as DHCP, and would like to have the ASA run in transparent mode and perform IDS/IPS.  I need the ASA to provide VPN connectivity and not the 2800 router.  Is this configuration possible.

you cannot have the ASA in transparent mode and simultaneously have it be the VPN endpoint.

ok so assuming that I cannot have a transparent firewall be a VPN endpoint, then how should this configuration be done. I would like the ASA to be the VPN endpoint if possible.

The ASA can do VPN, NAT and all access control along with IPS/IDS
The Router can just pass packets from WAN to LAN interface.
If you have an Ethernet feed for WAN, then the router is useless.

The ISR is going to be for a VOIP deployment in the very near future.

are you saying that the 2800 should not be inline with the asa?

Not if you have Ethernet WAN feed.
What kind of PSTN feed are you planning? PRI or SIP trunk?
