Hello,

When using the UPC internet connection, the name local.ipquants.com cannot be resolved

dig local.ipquants.com @ns2-08.azure-dns.net.
; <<>> DiG 9.10.6 <<>> local.ipquants.com @ns2-08.azure-dns.net.
;; global options: +cmd
;; connection timed out; no servers could be reached

and the UDP request fails

tcpdump: listening on en0, link-type EN10MB (Ethernet), snapshot length 524288 bytes
11:07:07.524309 IP (tos 0x0, ttl 64, id 29281, offset 0, flags [none], proto UDP (17), length 75) 192.168.0.77.50101 > ns2-08.azure-dns.net.domain: [udp sum ok] 39719+ [1au] A? local.ipquants.com. ar: . OPT UDPsize=4096 (47)

This behaviour started earlier today and occurs only when I am connected with the WiFi.
Tested with Personal Hotspot from phone and works fine.

Any help is appreciated.

Thank you.

bvasil Welcome to the community!

NAT Loopback is not activated on the modems. Here you would have to either use your own router and our modem in bridge mode, or adjust the hostfile in Windows.

Greetings

He should still get a valid DNS answer though:

dig local.ipquants.com @ns2-08.azure-dns.net

Does he maybe have surf&protect active?
