CISCO router 827 - VPN ezvpn configuration

I'm facing with this simple configuration and I can't figure it out.

Scenario:
With a Cisco VPN client (or iPad, iPhone..) I can connect to my company VPN. What I know is:

   VPN GROUP NAME
   VPN KEY
   VPN SERVER PUBLIC IP
   VPN USERNAME and PASSWORD
   IP address of virtual adapter created by Cisco VPN client: 10.0.201.31 255.255.255.0
   My LAN 172.23.28.0 255.255.255.224
   Company LAN 172.19.248.0 255.255.252.0

The question is "How can I handle this for my home's LAN with a Cisco 827 router?"

I think the steps are:

1. configuring eth0, dns and dhcp (done)

2. configuring ATM0 and Dialer0 to get internet access (done)

3. configuring access list and IP routes for my LAN (done)

4. configuring ezvpn parameters (done)

5. configuring virtual interface with Ip 10.0.201.31 (What kind of interface?)

6. Set inside and outside nat for "crypto ipsec client ezvpn MYVPNTUNNELNAME" (which interfaces and how ?)

7. configuring route to 172.19.248.0 255.255.252.0 (how?)

Here is my configuration:

    end

End of configuration.

Please note: If i add

    crypto ipsec client ezvpn MYVPNTUNNELNAME

to Dialer0 and

    crypto ipsec client ezvpn MYVPNTUNNELNAME inside

to Ethernet0

I get this:

    Tunnel name : MYVPNTUNNELNAME 
    Inside interface list: Ethernet0,
    Outside interface: Dialer0
    Current State: READY
    Last Event: CONN_UP

Solved!!

Thanks to James help i switched ezvpn conf to "mode client" and with debug i noticed that the problem was on server side, cause "storage-password enable" was not set. When company's net admin told me that "storage-password enable" was set i just did:

conf t
int Dia0
crypto ipsec client ezvpn MYVPNTUNNELNAME

....and everything works perfectly :-)
