Which firewall to connect VPN to?

I'm building a dual firewall solution for exchange.

Currently, I also have people connecting VPN to the PIX 515E.

Internet ==vpn== 5505 == LAN

Looking to set up

PIX515E ==dmz== Edge server == ASA 5505 == LAN

In a setup like this, which device should I have people connect VPN to? The pix will be the only device directly connected to the internet. Everything else will be natted.

The Pix515 for vpn as you dont want to have NATTED vpn headend. Also, I am not sure why do you want :-

PIX515E ==dmz== Edge server == ASA 5505 == LAN

Rather than

Internet ---------  ASA5505 == Lan

                          ||

                       DMZ servers

Most of the documentation I've been reading has suggested that

PIX515E ==dmz== Edge server == ASA 5505 == LAN

seemsto be the best practices setup config for exchange with an edge server.

Not sure about these Blogs , but I have always seen firewalled Network with either Inside/Outside or Inside/outside/DMZ configuration only ( more often inside/outside/dmz ).

I think the inside( 100 )/outside ( 0 )/dmz ( 50 ) security setting would logically look like a Two firewall design as lower to higher traffic will be scaned against Firewall rules etc.
