[c-nsp] NAT question

[Raz]

Hi,

 I would like to know if  I can access an email server running behind a
NAT router with static mapping from within the LAN by using mail servers
FQDN e.g mail.xxx.com existing setup is

Outside Client X ---> Router-with-NAT------>Mail server sitting on LAN

what if the same user Client X tries to access the mail server by using
its hostname mail.xxx.com which resolves to NAT routers public IP
address, I would like to know is it possible to let the Client X use the
same hostname regardless of its source network either publically or from
within the LAN.


Cheers
