So I believe host tries to reach DNS sever over wrong address. Go to Solution. I have spoken to Cisco and apparently this is a change of behaviour meaning it will not be fixed. But from ASA 9. View solution in original post. Therefore DNS requests don't send through tunnels. We are not allowed split tunneling, therefore VPN clients unable to resolve domain names. It doesn't have the capabilities of a DHCP server but it can allocate addresses to clients. Thank you for your comment, but the issue is anyconnect client assigns this route by using the DHCP server of physical host not the VPN client.
There are several secure PCs use anyconnect to access secure domain over the corporate network. These users aren't coming from outside, tunnel initiate inside the corporate network. I'm not sure I understand. We have secure domain within the corporate network and access this secure domain over the VPN tunnel. I realize that this is an older post, but I don't suppose anyone found an answer to this issue? I am having the same problem now that we have moved to Anyconnect 4.
This worked for us, but one side note. I had to upgrade the AC client to a newer version. The custom attribute workaround did not work with AC version 4. Also set an Alisas for the Connection.

If you have Windows servers, right click on your DNS server in a console, go to Properties, then Forwarders and make sure you have something like even the google DNS 8.

Xhostc ontrols the access of a remote host running a terminal on the endpoint, which is restricted by default. Without disabling access control, AnyConnect web deployment will fail.
With the fix of CSCvu and its device ID computation change, certain deployments of Linux particularly those that use LVM experience a one-time connection attempt error immediately after updating from a headend to 4. Linux users running AnyConnect 4. A new connection attempt to the same or another secure gateway is needed, which requires re-authentication.
After an initial upgrade to 4. The Network Access Manager made a revision to write wireless LAN profiles to disk rather than just using temporary profiles in memory.

Likewise, our crypto toolkit has discontinued support for RC4 ciphers; therefore, our support for them will be dropped with releases 3. After a fresh installation, you see ISE posture log trace messages as expected. If you are using macOS Disable the captive portal application; otherwise, discovery probes are blocked, and the application remains in pre-posture ACL state.
The Firefox certificate store on macOS is stored with permissions that allow any user to alter the contents of the store, which allows unauthorized users or processes to add an illegitimate CA into the trusted root store.
AnyConnect no longer utilizes the Firefox store for either server validation or client certificates. If necessary, instruct your users how to export your AnyConnect certificates from their Firefox certificate stores, and how to import them into the macOS keychain.
