  • Exchange 2013 on Dynamic IP

    Hi All,

    I'd like to setup and learn Exchange 2013 on my server at home, but my ISP (Optus) does not provide static IP addresses to cable users. How can I run up and use an Exchange server and get around being blacklisted etc with a dynamic IP?

    I've read a bit about smarthosts and DDNS and think that one of these may in fact be the solution to this issue, though the latter I believe has risks with being blocked.

    Because we are so far away from the phone exchange we gave up on the painful speeds and dropouts of ADSL2+ and moved to Cable, so unfortunately ADSL is not an option, which could have had a static IP. We also no longer have a home phone, so I can't even do dial up (*shudder*).

    Finally, as this is personal I'd prefer to keep the costs as low as possible, without writing off the fact that I may in fact have to spend some money to make this work.

    Thanks!

    the bigger problem you're likely to hit is that Optus won't allow you to make outbound port 25 connections.
    Probably cannot make inbound port 25 either and i know from my own experience with Optarse cable, that i can't seem to open port 80 inbound either. I havne't explicitly tried 443, but suspect that may not work either.


    option: Azure or Amazon virtual server, with a VPN tunnel back into your optus connection.
    all the inbound/outbound traffic relevant for your exchange server can be punched over the VPN, Optus can't see the traffic and thus can't block it..

    you could probably get away with a very small Amazon instance with a Vyatta virtual firewall..

    (PS, they also aren't fully dynamic ip addresses. I had th same one for 2 years with optus, I only got a new one when i put a new device with new MAC addr on the line)

      Hi, one free method is to https://www.noip.com/ you will need to setup your redirect and install the dynamic update client on the exchange server, but it's all free.

      You can check if port 25 is blocked by using http://www.canyouseeme.org/

      I do tend to think 'outside the box' so others may not always share the same views.

        Thanks for the feedback guys.

        I checked with Optus before subscribing after advising of what I was wanting to do, they confirmed that they could open port 25 upon request, though I did not ask about both directions..

        Yep, can confirm they lock port 80 from experience, however port 443 seems to get through, was using it to log in remotely.

        I'll check out the suggestions and links - cheers.

          worst case for outbound, you make your outbound connector smart-host to the Optus server rather than via dns.

          (OR, if possible, smarthost to some sort of AV/Antispam engine where you can connect on port 465 or 587)
