ZAC app blocked by router

GrahamF1 — Fri, 07 Aug 2026 12:27:06 GMT

My comany uses the ZAC softqare to route telephone calls when I work from home, it used to work fine, but has stopped working, thingkin back it was after I had to tinstall the new sky router.

My IT dept tell me it probably a problem with the router blocking access to the following urls:-

elmmx.elmdene.co.uk

ping.elmmx.elmdene.co.uk

tracert.elmmx.elmdene.co.uk

If you try them they just time out.

What setting needs to change to give ZAC the access to work pleasse

@GrahamF1elemdene.co .uk routes correctly but your three addresses do not. Check the settings of the Broadband Shield in the My Sky app or website as there aren't any relevant settings on the hub you can change.

I tried using a Google's public DNS to rule out an issue with Sky's DNS on my own Sky connnection and repeated via a mobile network both of which also timed out which tends to imply there is an issue at the sites end.
