SD-WAN

The flow details will always show IP addresses for IP1 and IP2, so that is expected.

For first packet classification, the EC would need to snoop DNS. Is the DNS server request and response also passing through the appliance? If not, your symptoms are expected. If you can get the DNS flows to route through the appliance, I would expect it to be able to place the flow into the correct overlay from first packet and show the 'First Packet Dst Domain' in flow details under the AVC/DNS tab, example below:

Sorry I don't really get your message, here is what I get for the destinations which I have issues:

In the flows, I can see a lot of FQDNs in IP2

Example :

Interesting that the src domain was DNS snooped successfully, but not the destination.

Which version of ECOS are you running?

had the same issue. if you run show dns cache on any version of 9.4.3.x your be met with the following output

Only fix will be 9.4.4.2 + as was confirmed to me by Aruba there will be no 9.4.3.8

Hello,

Our partner has updated the Edgeconnects to the 9.4.3.5_99663 version, it worked during a while, doing the resolutions correctly.

But recently it's again doing the same issue, not resolving the IPs to FQDNs for certain destinations, and then our ACL is not working, as it's filtering to domains.

Sorry I don't really get your message, here is what I get for the destinations which I have issues:

In the flows, I can see a lot of FQDNs in IP2

Example :

I've found the problem, this ECs is a hub and has a default 0.0.0.0/0 route to the core switch of the site, the DNS resolution was set with "any" interface, so when it was using the LAN interface the resolution was "redirected"

If I ping from the CLI without indicated interface I can see it's using management interface.

So I defined the DNS resolution using mgmt0 interface and now no more DNS resolution issue in the flows.

It was working with the other ECs because they are spokes without local default route and using loopback for DNS resolution.
