Problem with NAT loopback

ChriZathens

Hello guys!

I would appreciate your help.

I installed XG (long time Home user of the UTM), latest version as of today (SFOS 18.5.2 MR-2-Build380)

My problem is that I want to access my cameras and I am creating a rule for the camera specific port. I am using Server access assistant, fill in the necessary details, the wizards tells me that it will create the necessary rules (including loopback) but after the rule is applied I cannot access the camera from inside the network. Using 4G can access it normally..

What am I missing?

Is there anything else I should do? (the camera is created as a separate host and the specific port is added in services)

Thanks!

    Hi ChriZathens,

    Please check you have rule as per the below snapshot and try to resolve the issue with packet flow with tcpdump and drop packet capture :

    Hello and thanks for the reply.

    No, it is a public IP. However what  I omitted to clarify before is that I was trying to access using a dynamic dns name and it was not working. Do I need to add each camera to WAF, too in order for it to work?

    As mentioned, I am used to the UTM way and in UTM only NAT was needed

    The loopback rule is added automatically. I used the assistant

    Hi ChriZathens , 

    NAT lookup will created automatically I am suspecting issue with firewall rule  as per the snapshot I have shared 

    Also Check DNS is getting resolved under CONFIGURE--->Network --->DNS and click on "Test Name Lookup"

    Thanks and regards

    It turns out after adding multiple WAF rules using using each camera port and the same dynamic dns name, it worked..

    Not sure it should be this way, though..
