NAT emails to my Exchange Server using NETGEAR DG834

Hi all,

I am trying to NAT my emails through to my exchange 2003 server.

I am using dyndns as I only have a dynamic IP Address.

My Exchange Server has a 192.168.1.* static IP address and my dyndns for example would be emailserver.dyndns.org

Using the NETGEAR DG834, how would I route my emails to the exchange box?

(MX10 is pointing at my dyndns address)

Any help woud be greatfully recieved,

M
