OK. Thanks to Rich and ManU. They both worked. TonyStop The World, I want To Get Off! ........... Life Isn't About Waiting For The Storm To Pass ... It's About Learning To Dance In The Rain.

I'm sorry. I did not realize this before my previous post. These two methods suggested yield two different IP addresses. The nslookup gives the Arvixe A record address for my mail.domainname.com. The http://whatismyipaddress.com/ yields the IP address of my router from Verizon. Which one is my Exchange server IP address? Thanks, TonyStop The World, I want To Get Off! ...........

Your Exchange server will have a different IP address (probably on a private IP network) to your router. But what I think you're really asking is "what is my Internet-facing IP address?" That would be the one from the URL I gave you. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Rich, I asked Arvixe support a question about blocking port 25 for outbound exchange email and here is what they replied: "It appears that you haven't updated your MX records to reflect that you are using another mail server for your email needs. I would suggest updating the MX records with the IP address of your exchange mail server, and then getting a RDNS (ptr record) for email server as well. Please let us know if you need more assistance." They specifically say "the IP address of your exchange server". That's why I asked for it. Is my IP address for the exchange mail server the same as my Internet-facing IP address? Thanks, TonyStop The World, I want To Get Off! ........... Life Isn't About Waiting For The Storm To Pass ...

I have no idea want your domain name is, or what your router's IP addresses is, or if you have more than one IP address. Neither do I know whether you expect e-mail to arrive directly to your Exchange server or if you use a 3rd-party SMTP relay that accepts the mail and then sends it to your Exchange server. Nor do I know how you have your outbound e-mail configured. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

It probably is. I have no idea want your domain name is, or what your router's IP addresses is, or if you have more than one IP address.

Nor do I know how you have your outbound e-mail configured. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP Rich, OK. So I still do not know how what the IP address of my exchange server is. If you are saying "probably", then it sounds like you are not sure. I was not asking you all of those other questions. I'm just trying to figure out the answer to one question. Thanks, TonyStop The World, I want To Get Off! ........... Life Isn't About Waiting For The Storm To Pass ...

I have no idea how your DNS is populated or what the internet-facing name of your Exchange server is. YOU, on the other hand, have all that information. >I was not asking you all of those other questions. No, you weeren't.

Hi Carneno, You can use http://www.whatismyip.com/ to check your exchange external ip, as you said in your post it is showing your router external ip that means you don't have external ip set for your exchange. It is behaving in a same manner if you run above url on any desktop user' system it will show your internet facing router external ip.

Hi, Go to whatsmyip.org This will give you your external IP. There's no "Exchange Server" IP Adress. It depends on how your records in public DNS are setup. If you have only one Internet Router, no load balancing stuff in your organization, then u'll probably have only one public IP. Ask the guys hosting your public DNS if your MX record is pointing to the right public IP u'll see on whatsmyip.org

Thanks for everybody's help. From what everybody has told me, our Exchange external IP address is the same as the public IP address. Thanks, TonyStop The World, I want To Get Off! ........... Life Isn't About Waiting For The Storm To Pass ... It's About Learning To Dance In The Rain.
