AnyConnect compatibility in Windows 10 20H2 We are preparing to upgrade our client environment to Windows 10 build 20H2 and are attempting to confirm if any compatibility issues exist. We are currently running AnyConnect v4.9.04053. VPNs (including AnyConnect) + Standalone Roaming Client + Windows 10: DNS Binding Order VPN compatibility mode: Currently, there is a limited set of users on Windows 10 which encounter a specific issue where the local LAN will bind above the VPN NIC for DNS.

Cisco Anyconnect Compatible Vpn

Openconnect is a VPN client, that utilizes TLS and DTLS for secure session establishment, and is compatible with the CISCO AnyConnect SSL VPN protocol.
VPN with Compatibility with Cisco AnyConnect? I have a Cisco Annyconnect VPn setup (autheticate with RSA SecurID on my phone), and purchased PIA access on the recommendation of a friend. I can occasionally get PIA to work, but it usually requires a reboot, and it's not consistent.

How the VPN works

The VPN is extremely simple, based almost entirely on the standardHTTPS and DTLSprotocols. You connect to the secure web server, authenticate usingcertificates and/or arbitrary web forms, and you are rewarded with astandard HTTP cookie named webvpn.

Some Cisco servers require you to execute a 'Cisco Secure Desktop'trojan binary (intended for security scanning of the client system)before authentication can complete; see the CSDpage for information on how to comply with this requirement, orspoof it, with OpenConnect.

After authentication, you use the webvpn cookiein an HTTP CONNECT request, and canthen pass traffic over that connection. IP addresses and routinginformation are passed back and forth in the headers of thatCONNECT request.

Since TCPover TCP is very suboptimal, the VPN also attempts to use UDPdatagrams, and will only actually pass traffic over the HTTPSconnection if that fails. The UDP connectivity is done using DatagramTLS, which is supported by OpenSSL.

DTLS compatibility

Note: DTLS is optional and not required for basic connectivity, as explained above.

Unfortunately, Cisco used an old version of OpenSSL for their server,which predates the official RFC and has a few differences in theimplementation of DTLS.

OpenSSL

Compatibility support for their 'speshul' version of the protocol isin the 0.9.8m and later releases of OpenSSL (and 1.0.0-beta2 and later).

NOTE: OpenSSL 1.0.0k, 1.0.1d and 1.0.1e have introduced bugs whichbreak this compatibility. See the thread on the mailing list, which has patches for each.

If you are using an older version of OpenSSL which predates thecompatibility, you will need to apply this patch from OpenSSL CVS:

http://cvs.openssl.org/chngview?cn=18037 (OpenSSL RT#1751)

For versions older than 0.9.8j, some generic DTLS bug fixes are also required:

http://cvs.openssl.org/chngview?cn=17500 (OpenSSL RT#1703)
http://cvs.openssl.org/chngview?cn=17505 (OpenSSL RT#1752)

The username/password for OpenSSL RT is 'guest/guest'

GnuTLS

Support for Cisco's version of DTLS was included in GnuTLS from 3.0.21 onwards (commited in fd5ca1af).

When you are off campus, some of Illinois State University’s electronic services are unavailable to you unless you establish a VPN connection.

Cisco AnyConnect is an application that the University makes available to students, faculty, and staff for free which may be used to establish a VPN connection with the University from off campus.
