    Default dyndns - success

    I can successfully send and receive messages from my dyndns hosted domain name. There are issues, but it does work.

    * Home based server behind an ISP firewall
    * Ubuntu 6.10 with splitdns configuration
    -- Configured as a domain name that I have registered
    -- external zone should never be seen by the outside world
    * Dyndns using a custom dns service ($)
    -- pointing my registered name at my current isp assigned address
    -- A dyndns updater client running to keep the ip's in sync
    -- (No reason to believe the free dyndns hosts wouldn't work)

    Currently, my outbound messages are frequently rejected or spam filtered by receiving mail host due to (I presume) lack of credible hostname resolution. I may need to use my outbound ISP smtp (if it will allow relaying) or I can set up MailHop Outbound ($).

    My inbound port 80 is blocked, my inbound port 25 is NOT. Your mileage may vary. I can use mydomain.org:8080 (works now) or use WebHop to cloak the port mapping (in progress.)

    I have one of my installed servers running a similar config:

    FC5
    No-IP for DNS (paid version)
    Using client-side IP address updater (actually 2 of them for redundancy)
    Using ISP for SMTP transmit

    My ports 80/25 (and any others I need) are open and usable for zcs

    Works great.

    Default More explanation

    Please say your configuration in detail.

    I will hear of your OS, router, ddns service and Zimbra's configuration.

    Default split dns howto

    ok -- that was a long time ago now.

    I did write a howto on creating a dynamic dns settup (splitdns.) There may be much better ways and tools that will do this via a graphical ui by now.

    There are LOTS of times when you want to create two different views of the addresses on your computers -- one from behind your firewall and a different on from outside your firewall. It just allows the same name (server1.mysite.org) resolve into two different ip addresses depending on the location of the machine asking. In my case:
    -- inside = server1.mysite.org --> 192.168.xxx.xxx
    -- outside = server1.mysite.org --> 72.xxx.xxx.xxx (dyndns mapped)

    DigitalManor / FrontPage

    good luck with it.

    I'd love to move this howto someplace where others can comment/add to it. Suggestions?

    There are several such guides already on the wiki; here are two that I wrote:
    Dapper Drake Install Guide
    Hardy Heron Install Guide

    I noticed that your guide has a lot of the same issues I dealt with. You may want to make some suggestions on the wiki (for example, I didn't address DDNS at all), or if you feel there's enough difference, you may also want to write your own. We certainly welcome the input.
    Cheers,

    i have a setup running similar to this using no-ip.com.

    The big pain I have is that I can not seem to get the server to run on a subdomain e.g. .hostname.no-ip.org ... well I actually want mail.hostname.no-ip.org as I have a web server running on hostname.no-ip.org.

    I know the hostname is actually a subdomain but I figured it should be possible, however I have not a master at this stuff 'obviously'.

    I considered trying for hostname.no-ip.org/mail (as I am running apache on the same server to host the web site) but alas I couldn't get that working either.

    There are many guides out there which address how to do this with a proper setup (i.e. with an owned domain name) but not (that I could find) with a dyndns.

    Anyone of you guys tried this?

    Default glad to know I can put mine to bed...

    Dan -- Excellent -- glad to see that it's covered. I wrote up the howto as an personal exercise in learning dns which started from the desire to get a personal mail server running. I'll put mine to bed.

    Danoij -- you can create a url forward to a url with a specific port number.

    forward mail.yourdomain.com --> yourdomain.com:xxxx

    Set up your mail (or web) server(s) on the specific port(s).

    dns doesn't allow port munging.

    Mr. Tractor!

    sorry another noob just joined your website and already firing alot of quesitons..

    basically i have everything up and running and can access everything with webmin web admin / and the user interface of the zimbra,

    however, i am using dyndns the free version, the only thing i am paying for is multiple ip update in an hour meaning dyndns wont ban me!,

    anyway i have no idea how to setup my http://eject.mine.nu with the zimbra say i want to have an email of my own as hunter@eject.mine.nu

    no matter what i do i cant figure out what to put where.

    i have searched the forums but cannot find a tutorial...actually i am willing to pay for actual domaain like EJECT.COM but have no idea if it will have those MX records or whatevers needed to run a mail server.

    many thanks for your help

    regards
