Tks again David,

As you said to, i've created an alias in the dns hostname table. the alias
works perfectly. But is there possible a solution where the PC's in the
local lan can access the mailserver using the public name (mail.xxxxxx.xx).
where you gave the alias solution, i thought it would be possible to create
an alias mail.xxxxxx.xx but it isn't... as i said, i'm a newbie.

tks for your time. Regards,

Bill.

OOpss, you're right...

And about my last question (is there possible a solution where the PC's in
the local lan can access the mailserver using the public name
(mail.xxxxxx.xx)? ), have you any suggestion, please?

Some NAT implementations seem to do this, and some don't. But in any case,
it will be much slower to do it that way, so you really don't want to. The
FreeBSD NAT router that I used to use had that effect.

The usual solution to this problem is to run split DNS. Have one DNS server
on the internal network, which gives the 10.* addresses for names of your
machines. The one used from the outside, which may really be outside, or
found using port forwarding through the NAT router, returns the outside
address. The inside DNS server then goes outside only if it can't answer
the request from its own data.

Now this thread is on topic for comp.protocols.tcp-ip.domains, which it
otherwise would not be. So why did you post there?

That doesn't make sense to me. Don't do that.

If I understand your problem correctly, you'll need a better router. Either
one where you can set the IP address of the mail server to the external
static IP or a router that will handle the DNS situation you have. I saw
this discussed in relation to a Mac software router where the developer
specifically added the ability to deal with this and it was discussed as
being not commonly available.

LOL.

Bill, he's already told you once...

Create a HOSTS table line item identifying the Local IP of the mail
server. This way when you use the alias on the LAN side, it will resolve
to the LAN IP.


Steve.

David: Tks again for your help.
Steve: This answer do not resolve totally my problem: it allows create an
alias, for example "mailserver", but i need the real name "mail.xxxxx.xxx".

Have you tried an entry like this in your hosts file?:
123.123.123.123 aaa.bbb.ccc wobblywilly

It works for me:
[steve@StevesPC steve]$ ping aaa.bbb.ccc
PING aaa.bbb.ccc (123.123.123.123) 56(84) bytes of data.

[steve@StevesPC steve]$ ping wobblywilly
PING aaa.bbb.ccc (123.123.123.123) 56(84) bytes of data.

I'm sure it should work on windows too.

Steve

Dang, something wrapped that hosts file line.
It shoud read all on one line:

123.123.123.123 aaa.bbb.ccc wobblywilly

Steve

You're right! it works! (the hosts file is in
c:\windows\system32\drivers\etc directory, in a XP system)

Thank a lot, Steve.

David: Probably this answer is the one you mentioned since your first
answer. sorry, i didn't understoud... shame on me.

Tks again you two.

Bill.
