ipsec vpn client on iphone in order to connect to exchange 2003 server

Hi there,
I have on my internal network one exchange server 2003.
I have too a ipsec vpn firewall who permits users from ouside to connect to internal network.
I have some nomades users with iphone 3 and 4.(we want to keep original os)
I would be great if nomades users could connect to the vpn server and download messages on iphone.
Is it possible ?
Do you know if iphone have a ipsec client ?

Yes, iPhone has native IPSEC client.

Go into Settings --> General --> Network --> VPN and you can add IPSEC VPN from there.

As Spartan_1337 stated, yes, the iPhone can have an IPSEC VPN connection.

Have you considered setting up ActiveSync for your Exchange server? Or you could enable POP or IMAP access on your Exchange 2003 server and your users would not need VPN at all.

Hi

I know that Iphone have a native ipsec but it is a light client.

The native doesn't permit authentification only account, password.(mutual PSK) and remote identity.
 
It is necessary to have secret.

Thanks,

This all depends on how your VPN is set up:

Description: (Describes the VPN Connection) ex. My VPN
Server: (Address of the VPN Gateway)
Account: (Your VPN Account Name)
Password: (Your VPN Account Password)
User certificate off (or on if that is configured)
Group name (The Name of the VPN Group your VPN account uses)
Secret: (The pass phrase that the VPN Group uses)

All of this information should be available from the person or group that administers your VPN service.
