ZyWALL USG 20 Phones Home Daily to ZyXEL

The ZyWALL USG 20 phones home daily to ZyXEL supposedly to verify the status of any supplemental licensed products even when there were never any installed or currently registered. There is no provision to disable this "feature." Technical Support suggested that ZyXEL wants to monitor the status of the devices for unspecified reasons but could not identify what information is actually sent.

If you prefer that your equipment not to report back to ZyXEL just to stay in touch, please send a note to that effect to support@zyxel.com and refer to case number 147179.

It sounds interesting. Thank you, u475700 See Profile for heads up. I don't run this model right now. Can anybody else check and confirm that too?

The last thing one would expect (or wants to discover) from router is that it phones to some host on the Internet without explicit permission of its owner...

This is known issue with the USG series unfortunately.
The other is that there are hard-coded DNS servers that USG uses for "system" type requests i.e. NTP time.

Both issues should be fixed and user should be able to control it ... unfortunately ZyXel seem to care very little

EDIT: Now I'm not sure, there are either DNS servers hard-coded or NTP servers hard-coded, or both. I'd need to do some sniffing to refresh my memory.

i have added dns servers to custom ip addresses and added them on top of the default dns server (which i detest).
i am using opendns.com

seems to keep that deplorable uneditable dns server out of the loop.
