SOLVED - Accessing mail server on my network?

Hi all, I have a Zyxel Prestige 660HW-T1. One machine on my home network runs a mail server (POP3 on 110 and SMTP on 25). I have got NAT and firewall set up fine in the 660HW-T1 so that I can reach the mail server from the outside, using my ISP account static IP, from my laptop. That's all fine. What isn't fine is that I cannot access the servers when the same laptop is at home. I have to modify the mail client settings to use the internal IP of the mail server box.

Is there anything I can do to allow me to use the external IP to access the mail server, even when I'm internal? This used to work fine on my previous routers (various different makes) - it's only this Zyxel that seems unable to do it.

Glad of any advice.

thanks, Andy

I did try searching various forums before, but now I've worked out what the feature I need is called - NAT loopback - it took no time at all to find a post over at DSLReports that answers my question:

Although this is for a different Zyxel model, the same worked for me.
