Mail flow contingency for two internet breakouts.

    Question

  • Hi guys

    Please could you advise as to the following setup configured for my Exchange server.

    Our building consists of two internet breakouts, whereby the standalone 2013 Std server are configured by a public IP of the one ISP for all mail flow. We had an incident recently where this ISP line was faulty, and the second ISP line took over.

    All desktop PC's and so forth were unaffected by the change of ISP for internet availability, which is not the case for the exchange services. My question is how and if possible can I configure Exchange to have the same automatic switch to the second ISP line when there's an incident like this again, having no or little disruption to the email flow and connection to Exchange from all desktops.

    Regards

  • Hi,

    Yes, as said by Ed there is nothing required from Exchange server as its Standalone server.

  • It's the network that should be failing over to the live link.

  • Exchange isn't network aware in that sense.  I'm afraid that this is the kind of thing you need to configure in your network router for outbound traffic, or a dynamic DNS service for your inbound traffic.

  • Hi,

    I would recommend you to check with Networking Team for such failover in the ISP (lease lines). Also you can configure clustered Proxy servers for such ISP failover to happen.

  • Ed, thanks. So essentially this needs to happen on the firewall side and nothing much really within Exchange itself?

  • Hi Praveen

    Thanks for the feedback. As stated above to Ed's comment, the failover and clustered proxy servers are required from the networking team, with no configuration to be done on Exchange?
