Hi,
I was given a MacBook Pro, M2 chip for my work, running Ventura 13.5.1.
In order to access corporate websites, I was told I need to connect to a VPN using Cisco Any Connect.
I was given an installer (predeploy) for version 4.10.05111.
After having installed the client with all extensions, activating the extension in my Settings and allowing the Socker Filter to filter network content, I cannot seem to be able to connect to the internet.
So far I have not even tried to connect to any VPN.
I uninstalled it using the Unistall AnyConnect application. But even after doing that, I have no internet access!
The wifi is connected, I tried another network and even sharing mobile data without success.
I tried to ping google.com but I get an error message: “cannot resolve google.com: Unknwn host”.
When trying to ping 8.8.8.8 (Google DNS) or 142.251.46.174 (google.com IP found online), it does seem to work. Putting the last address in my browser does not work. The GET request to the IP address gives me a 301, but the subsequent call to google.com is bloqued with NS_ERROR_UNKNOWN_HOST.
What is wrong with my network connectivity? Is something up with the DNS?
This is a corporate AnyConnect and a corporate MacBook? Contact your corporate helpdesk. It is possible they have things setup where you can’t access the internet unless connected to the VPN and using their internet.
You pinging 8.8.8.8 shows that you have internet access.
You have an issue with DNS. What DNS servers are set for your network adapters?
AnyConnect likely is going to force your internet and DNS traffic over the VPN since it is a corporate managed device.
Have you tried connecting to AnyConnect first then using the internet?

wouldn’t the best people to speak to is the company’s IT support? as its their system and infrastructure.
they can log in and check stuff with you to troubleshoot.
Open command prompt and type:
Ipconfig /flushdns
Hit enter
Turn off wireless and turn back on.
look for the umbrella service which forces the computer to use the VPN DNS even when not connected to VPN.
The MacBook is corporate, AnyConnect I don’t know I was given a dmg from a colleague to install.
I work from home and so far had not used any VPN, but the Mac was already set up a little when I got it (why not with Cisco already working I don’t know…).
I feared I might have to send it back so I wanted to see if someone knew this problem and could help. Helpdesk had not been helpful on this matter.
Thanks anyway
So I removed the DNS servers that I found within the wifi connnection. It reset it to a completely different address, and now my internet works again thanks!
