Exchange 2007 uses internal IP Address to send RRS feed

  • Question

  • Greetings!

    I have some issues in with regards to the sending of the Exchange Server. It uses the internal IP Address of the server. I have two network interface cards and the other card has the public Ip address of 210.x.x.x Is there any way to circumvent this?

  • What you desire is Header Firewall. Our buddy Jeff wrote a nice and direct blog about this

  • @Joe Trombley Did it but still doesnt work. I can receive Emails from external networks, and emails in the same domain. But if I were to send email, I will receive Delayed Delivered email. I was thinking this might be the problem.

  • I just wanna do a recap. Before we had this problem where the Source IP is from an IPv6. Well, I read some forums and blogs which lead me here and I chosed the package "Prefer IPv4 over IPv6 in prefix policies" since exchange cant run without IPv6. Well, it did work, but I got stumped by this internal IP address which is the problem now, because now it gives which is a big pain really.

  • Hi,

    Any third party AVs or add-ins running against Exchange 2007?

    To circumvent to use internal IP send email, how about TMG?
