connected users having the same IP as the server

Hi guys,

I have just setup a small server , mainly for afp and VPN.

a quick network overview

ADSL->netscreen (NAT/dhcp server)->server (192.168.1.55)
->clients…

All goes pretty well except one thing.

I made 2 test users in OD (X and Y) , when X mounts an afp share, serveradmin shows the ip addres next to his name as being the same as the server! (192.168.1.55) , even when user Y mounts a share, same situation… (I tried with static IP’s for tha clients, still showing the server IP).

Any idea what I’m doing wrong here?
thanks for any help!
