Accessing the worldwide accessable NAT inside LAN

[DZEIDMAN]

I would like to access the worldwide accessable NAT inside our LAN.
We currently have an internal IP address 10.10.1.55 with a NAT attached to a valid IP address (e.g.: 205.x.x.x) accessible outside the LAN.
Users access this IP address to access a POP3 (port 110) connection.

How can I configure Checkpoint to allow access to the valid IP address (e.g.: 205.x.x.x) as opposed to the internal IP address 10.10.1.55 when they are working within the LAN?

If i understand correctly, you want to connect to pop3 from Internet on Valid IP and to pop3 from LAN on private IP. Is it correct?
In this case you can use one rule (any source | server_ip_private | pop3) and one object with private IP (using Automatic Address Translation rule in object properties).

I will clarify: I want to connect to pop3 from Internet on Valid IP and to pop3 from / within LAN on Valid IP and not the Private IP.

Really I don't know how use CP nat for that (if you use NAT on one CP module for pop3 server with private IP.)
May be more simple is using dns servers? And resolve dns name of pop3 server for WAN to external IP and for LAN to internal IP.
