If you need to add settings for DNS servers or Proxies when using the VPN please see the screenshots below for reference. Optional Set Up Steps. The settings below can be reached by clicking the Advanced button when viewing your VPN connection in the network list. DNS Servers and Search Domains. This is a package containing an OpenConnect configuration script for MacOS that allows you to fully control how the VPN connection is made, which routes are added, and how the DNS are configured. If you are tired of having all your private traffic go through the corporate VPN, but you need it always up, this script is for you. If your VPN DNS changes, you need to change it manually. This can easily be checked under Network → VPN interface w Advanced → DNS tab since your VPN DNS is still assigned dynamically to the interface (although ignored by OS X). If your 3G DNS changes (unlikely) you need to change it manually too. My guess is that you are running Mac OS X 10.7. In prior versions of Mac OS X, the command 'net' is located at /usr/bin/net. Apple removed Samba from Mac OS X 10.7 due to the license change to GPLv3. The 'net' command is a part of the Samba package and what Apple used to integrate with Active Directory prior to Mac OS 10.7. AnyConnect uses a network system extension on macOS 11, bundled into an application named Cisco AnyConnect Socket Filter. (This app controls the extension activation and deactivation and is installed under /Applications/Cisco.) The AnyConnect extension has the following three components: DNS proxy. App/Transparent proxy.

Since I started using the Cisco AnyConnect VPN Client, I had DNS issues. I could not fully figure out why this happens on my system, but all signs lead to an issue with scoped DNS queries on macOS. Whenever the VPN is established, macOS uses the wrong order to resolve DNS entries. This leads to DNS query timeouts, but under certain circumstances to complete DNS failures, as the system insists on using the unreachable DNS server.
The problem exists for a long time now, at least since macOS Mountain Lion. For a long time I had to live with this annoyance, as the issue persisted with every new version of the AnyConnect client. But now I found a workaround, maybe even a long-term solution. It is possible to tell the macOS resolver to use certain DNS servers for certain domains. Setting this up is rather easy:
After restarting the mDNSResponder daemon and flushing the DNS cache, I was all set. I hope this will become a long-term solution for this issue, that plagued me for so long.
Cisco AnyConnect is the recommended VPN client for Mac. The built-in VPN client for Mac is another option but is more likely to suffer from disconnects.
Overview
Stanford's VPN allows you to connect to Stanford's network as if you were on campus, making access to restricted services possible. To connect to the VPN from your Mac you need to install the Cisco AnyConnect VPN client.
Two types of VPN are available:
- Default Stanford (split-tunnel). When using Stanford's VPN from home, we generally recommend using the Default Stanford split-tunnel VPN. This routes and encrypts all traffic going to Stanford sites and systems through the Stanford network as if you were on campus. All non-Stanford traffic proceeds to its destination directly.
- Full Traffic (non-split-tunnel). This encrypts all internet traffic from your computer but may inadvertently block you from using resources on your local network, such as a networked printer at home. If you are traveling or using wi-fi in an untrusted location like a coffee shop or hotel, you may wish to encrypt all of your internet traffic through the Full Traffic non-split-tunnel VPN to provide an additional layer of security.
You can select the type of VPN you want to use each time you connect.
Install the VPN client
- Download the Cisco AnyConnect installer for Mac.
- Double-click the InstallAnyConnect.pkg file to start the Cisco AnyConnect Installer wizard.
