Re: IP Address ends with 0

You can do a reverse DNS lookup for that ip address and it will tell you it's
smtp110.rog.mail.re2.yahoo.com

You can just do simple test like I did, if you have an ISA server. and you
will see my point.

Can you prove it is an SMTP Server for Yahoo?

Can you show other examples?

This is just an example. What I mean by connect to it is try to ping the
ip
address.

When I ping it from internal, I got no response. If I ping it on the ISA
server, I got an response.

This example ip address it's an smtp server from yahoo.com. It try to sent
email to my server. But the ISA server terminate the connection with
status
saying "Failed connection attempt"

So I begin to do test. And it seems like ISA server does not like ip
address ends with 0.

When I do a ping from internal, there is no trace of it on the ISA server.
It does not show up in the log files, it not in the diagnostic log either.

Hi

I have a problem with ISA server, when I try to connect to internet
address
that ends with 0 (eg. 206.190.37.0) from internal network, I can not
connect
to it.

But if I do it on the ISA server itself, there is no problem.

Has anyone encounter this problem before?
