Work VPN unable to connect

[Whatever1]

Work laptop/VPN unable to connect as of 15/06/22.  Previously worked fine.

Router logs show DNS name resolution failure.

Other posts cite firmware version SG4K100136 as possible cause?

Can you advise?

Thanks.

I am having the same problem, they have sent me a new router which looks like exactly the same one I already have. Changed it over and still can not connect. Mentioned firmware to the guy the other day but he said it was definitely my router!!

Hi

Just an FYi for you, and please pass this to your ICT section, there is an identified issue with version 136 firmware for the Sagemcom router affecting some VPN connections. Changing the firmware resolves this.

A future firmware will fully resolve this in time.  If any of your colleagues have an issue with VPN and are using a sagemcom router running version 136 firmware, please direct them to our community and we will help quickly.

Final update, in case it helps others.  Our ICT section are now saying the issue was with the corporate filewall manufacturer, and whatever it was, it was that, that was preventing employees who use Talk Talk as their ISP, from connecting over the work VPN.   In this case it appears the router firmware change was not the answer (the prompt response from Talk Talk was much appreciated, however).

Hi,

Glad VPN is working.  I've sent you a PM about our interaction today.

Hi Michelle - thanks for getting back to me.  Now would be the best time.

Hello,

I'm sorry to hear this. We can make a change to the router firmware. This will take about 20 minutes to complete and the router can't be re-booted/switched off during this time. When would be the best time to do this?

Thanks
