Sophos DDNS service is not updating the IP

Xebato

Hello,

I have Sophos XG106 Firewall connected to VDSL line using the PPPOE and getting a dynamic public IP address. Since yesterday I have noticed the Sophos DDNS is not updating the IP.  The service is seems to be running and in the logs I see the correct IP been updated every 5 minuts. However when I do ping or nslookup for the hostname I see always the old IP. I have configured no-ip.com account and it is currecntly working fine.

XG106_XN01_SFOS 18.0.3 MR-3# service -S|grep dn
dnsd RUNNING
fqdnd RUNNING

My questions are:

- have any one else problem with Sophos DDNS ? 

- Is there other commands to check the Sophos DDNS service ?

- How I can know if the DDNS service is running on the Sophos side ? is there a website to show the DDNS service availability (like user portal) ?

Best Regards,

Xebato

    Hi ,

    I tried to replicate this issue in my LAB, but I was able to configure DDNS using Sophos service. 

    Could you please replicate the issue and collect the following logs from your firewall. 

    SSH into the XG firewall by following this KBA: Sophos XG Firewall: How to SSH to the firewall using PuTTY utility

    • To connect using SSH, you may use any SSH client to connect to port 22 of the SFOS device.
    • Select option 5 Device Management.
    • Select option 3 Advanced Shell.

    Run the following command to collect syslog: tail -f /log/syslog.log 

    You also need to put the CSC service in debugging and collect csc logs. 

    Run the following command to put the csc service in debug: csc custom debug

    Note: Run the same command to remove the service from debugging. 

    Run the following command to collect csc logs: tail -f /log/csc.log 

    Send these logs to me via PM. 

    Thanks,

    Hello Harsh, Thanks for your answer.  I can also create a new hostname successfully but will never be bindend with the public IP. I will send you now the requested logs.

    Best Regards,
