Running 8.5.2 release version, and the bug is back:
One IOT VLAN device (in.touch gecko dongle connected via ethernet) is not getting DNS, even though other devices on the network can get DNS, and can ping this device.
Last time this happened, I did packet captures which looked like this:
no. | Time | Source | Destination | Protocol | Length | Info |
---|---|---|---|---|---|---|
453 | 0.794275 | 10.0.64.104 | 10.0.64.1 | DNS | 82 | Standard query 0x1234 A intouch2.geckoal.com |
454 | 0.794441 | 10.0.64.1 | 10.0.64.104 | ICMP | 110 | Destination unreachable (Port unreachable) |
In other words, the IOT device (on VLAN with address 10.0.64.104) is sending a DNS query to the Peplink, and it appears the Peplink is blocking the request.
I opened a new ticket this morning: 25041234 The device is currently in the broken state with Remote Access enabled.
@sitloongs I hope someone from Peplink can diagnose it this time?
