Can't access some company sites though Broadband/VPN, but can through Mobile HotSpot/VPN

[barnagaz]

Hi

I know there are a number of threads relating to VPNs and DNS here but none seem to address the issue I am facing.

Using Window 10 and Smart Hub 2 Manager (Smart Setup turned off).

I connect to the company VPN and can access some internal company sites, on others, the domain cannot be resolved.

If I connect to the VPN over a mobile hotspot, I can access all sites with no problem.

I've spent a long time on this issue and would really appreciate any suggestions.

Thanks

I have found that the issue is with the BT DNS servers that, as many others have found, are configured in the Smart Hub in such a way that they cannot be removed.

If I configured Windows to use the Google DNS server, then my requests are sometimes unsuccessfully handled by the BT DNS server and sometimes successfully by the Google DNS server.

Effectively I can sometimes access my company systems, but only by luck.

Does anyone know a way that I can force all requests to use the Google DNS server that I have specified in Windows? I am contacting BT too in the meantime. If I can't resolve this, I will have to switch to an ISP that I can use for work.

you never said if in addition to smart setup you also turned of web protect in MYBT as that may help

Thanks for replying.  I don't have web protect activated.

BT Can't help. Just offered to replace my SmartHub2.

Going to buy a new router.
