Since the update to Big Sur Mac OS 11.0.1 VPN Cisco IPSec does not work anymore. My VPN services created on the default system VPN Type Cisco IPSec still do connect, but afterwards there is no IP traffic possible. Not even pings to IP addresses are possible. Open Network Prefrences. Open up your System Prefrences and select 'Network'. Click on the little.
Many organizations provide VPN access for the end-user in their company with a third-party tool named Cisco VPN client. This doesn’t work on any 64-bit Mac OS.
However, from Mac OS X 10.6, you can use the in-built feature named IPSec VPN ,so you don’t need to look around for any third-party tool. In this case, you might have to decode your .pcf file which contains all the configuration of your VPN setting.
Here’s the step by step guide for configuring it:
- Open System Preferences -> Network
- Click “+” to get more options where you have to select Interface “VPN” and VPN Type “Cisco IPSec“. Hereby give your proper description in “Service Name” and click Create
Once you create this, the main work out is to decode the “enc_GroupPwd” which you can’t simply copy and paste.
- Simply, open .pcf file that you got from your organization in any editor (e.g.: Notepad ++ ), and copy hostname and put it in your server address.
- Click Authentication Settings, and mention GroupName as per your PCF file. Now you will see enc_GroupPwd in your PCF file which you need to decode and put it in Shared Secret
There are many ways of getting a clear group password. However, I recommend using this link to decode it. Once you manage to set up all the required settings, you can simply press connect.

I set up my built in MAC VPN (Cisco IPSec) client, but it does not appear the client is getting my split tunnel details, it routes all traffic over VPN in the split tunnel list and any traffic that is not configured to go down the VPN tunnel appears to just get droped an it just does not pass that traffic out the local internet connection. On the MAC built in VPN (L2TP) configuration in advanced options, you see a check box for 'Send all traffic over VPN connection', but that option is not available in the MAC built in VPN (Cisco IPSec), would this check box be similar to the Cisco client, 'allow local lan access', that particular feature allows for split tunneling in the Cisco client. Is there a way for the built in VPN (Cisco IPSec) client to get the split tunnel rules? Thanks

I have not set up the Cisco VPN server end, but I have used a Cisco system from the Client end. I can therefore tell you often the IT department will have set policies in the Cisco VPN server to force all traffic to go via their system whether you as a user would prefer or not. This allows them to monitor and filter all the traffic.

Apple's own VPN server can be configured in a similar way, although I chose to allow non-work traffic to go via the users own connection.
