I connect to the office network via VPN using Cisco AnyConnect client.
Recently switched over to BT Broadband and not now able to connect - DNS resolution errors and timeouts.
Other devices non VPN work fine.
Already switched off Smart Setup but that failed to help
Any help gratefully received.
No problems connecting before you switched to BT?
To start with, try rebooting your machine.
Failing that, try turning on Port Clamping:-
Using a browser, navigate to 192.168.1.254
Click the VPN tab
turn on port clamping.
Hi - The port Clamping didnt solve the issue.
Im getting the following :
"unsuccessful domain name resolution"
Ive used my mobile hotspot to connect and that works fine!
Seems this is a common fault, I've copied and pasted the answer marked useful by 5 others from
"the anyconnect.xml file had become corrupted, meaning the format of the file was no longer usable by the VPN client. Connecting to another region (different set of VPN HEs) caused a new file to be downloaded, and then we were able to connect to the original HEs. We don't know why the anyconnect.xml file became corrupted, but this fixed the problem in all cases."
