hi david, so do you mean that the ip public from isp is used at pc router, and 
exchange server is using local ip (private) in our lan, right ?

  Your mx record point to your firewall (PC router)on the internet. There 
should be an option in winroute to redirect port 25 to your internal mail 
server! From the outside world it looks as if the mail server is the same as 
your firewall but it isn't. It will redirect SMTP traffic directly to exchange 
server, so your exchange doesn't have a public IP address.

      It's depending on ur pc router you use. If it is NAT enabled so you have 
to bind the mail server public address to the internet interface (Winroute in 
mind) and Map to the internal IP address of your mail server. Make sure your 
internal DNS is resolves to the internal users as well.

      hi guys,

      i'm plan to setup a new ex2k, and want to install firewall too.  i'm 
using a pc router (low cost) for internet sharing, and firewall.  the scheme 
like this :



      internet ---  pc router -- switch -- LAN

                                            |

                                          ex2k



      i'm confused at the ip public for ex2k.  from outside, ex2k server can 
only known if using public ip, right ? how to set the ip for ex2k, if i share 
the connetion  from pc router ? or is there better solution for my scheme ?  
can you explain to me or is there a good reference link ?



      thank's.....

      hery
