Sophos Firewall Dynamic DDNS failed to connect FreeDNS

Wepee

Hi, 

I have set up a free account with FreeDNS. 
My public IP address is pointing to the correct subdomain.mooo.com

However, I have a query about the hostname, SF only accept: subdomain.mooo.com.

But in order to work, you need to include the update key.

According to the URL link: Add a dynamic DNS provider

For FreeDNS to work, you need to have: Username + Update Key

Where to key in the update key???

I am lost.

Thank you.

    Unfortunately, my success was only short-lived.

    For some unknown reason, on the next day I checked success became failed

    The hostname: Just to be sure, could you review your freeDNS config, as this field is case sensitive?

    Believe me, I have gone thru it many times, in fact, I am sick of typing.
    I typed all the details once, like hostname, update key on a text file,
    so that I don't key in character by character, I just copy and paste.
    Repeat the steps when it fails.

    Please note that when I discovered it was unsuccessful this morning,
    My DDNS connection Namecheap also failed, all the columns show the value,
    except that:
    Last updated IP  = blank
    Last updated status = blank
    Last updated time = blank
    Failure reason = blank

    Pressing the edit button and copy and paste the required details and save again, did not solve the problem.
    I had to delete the whole entry, reboot the FW and start over again.

    There is something not right. Personally I don't think it is stable or some bugs may be the culprit, base on my assumption.

    Hello,

    Is your IP NATed, or do you see the Public IP in your Sophos Firewall?

    Actually I should be using = use IP port = pointing to my public WAN IP.
    I made a mistake in the picture attached.
    My firewall is connected to VLAN switch and it turn is connected to Fibre Broad Terminal Unit.
    My firewall is NOT connected to a router. 
    So to answer your question I am using  = use IP port, because my WAN IP is publicly reachable on the internet..

    Please if someone out there is free, got some spare time, create a new domain, by registering a new account from freedns.afraid.org
    Test it on DDNS service in SFOS. 
    If it is working please share your settings.
    If it is NOT working, "raise your hand up" and alert the Spohos Team, telling them something is not work in the firewall code.
    Thank you.

    I was running into an error as well. 

    But it is caused by freedns. If the password is to long, it will not work. 

    The online help is wrong here. We are not using the Update Key. 
    We are using Accountname + password for FreeDNS. Will get the online help updated. 

    Setting is straight forward: 
    Hostname + Username + Password. 

    Used an 16 digit password, which fails. Apparently, the API of FreeDNS does not support long passwords. With 8 digits, it worked.
