Cisco Anyconnect Pfsense



Introduction¶

In this article we will see a site-to-site VPN using the IPSEC protocol between a Cisco ASA and a pfSense firewall. PfSense is an open source distribution of FreeBSD customized for use as a firewall and router. You can install pfSense on a PC with two (or more) NICs, essentially turning it into a flexible security appliance. Sep 01, 2020 For pfSense software, browse to Status System Logs on the IPsec tab. For Cisco, run debug crypto isakmp and term mon (if not connected via serial console) to make the debug messages appear in a session. The output can be verbose, but will usually tell specifically what was mismatched. “No NAT” List on Cisco IOS ¶. OpenConnect is a SSL VPN client initially created to support Cisco’s AnyConnect SSL VPN. It has since been ported to support the Juniper SSL VPN which is now known as Pulse Connect Secure. Palo Altos Global Protect will also be supported in future and of course the own OpenConnect Server. PfSense as a Cisco AnyConnect VPN Client using OpenConnect Unknown bolt 2016-03-01. PfSense, as of 2016-03-01, does not support OpenConnect out of the box. However, it’s in the FreeBSD repository, and relatively easy to add. I had a similar cisco vpn client connection problem this morning after an update to pfsense 2.0.3-RELEASE (amd64):: Our problem was that a working cisco vpn client on an earlier version of pfsense 2.0.1-RELEASE (amd64) functioned even with the 'Transport' option set to 'Enable Transparent Tunneling'.

Step 1 - Installation¶

Go to System ‣ Firmware ‣ Plugins and search for os-openconnect.Install the plugin as usual, refresh and page and the you’ll find the client viaVPN ‣ OpenConnect.

Step 2 - Setup¶

The setup of the client is very simple. Just tick Enable and fill out VPN Server,Username and Password. Be sure that the FQDN matches the name in the certificateor you will receive an error. Also wildcard certificates can produce errors.

Once enabled, a new interface will be available for specifying firewall rules;Firewall ‣ Rules ‣ OpenConnect will appear.

Step 3 - Troubleshoot problems¶

To troubleshoot connection problems it’s best to login via CLI and start OpenConnect manually:

# /usr/local/etc/rc.d/opnsense-openconnect start

Look out for errors like

Azure Multi-Factor Authentication Server (Azure MFA Server) can be used to seamlessly connect with various third-party VPN solutions. This article focuses on Cisco® ASA VPN appliance, Citrix NetScaler SSL VPN appliance, and the Juniper Networks Secure Access/Pulse Secure Connect Secure SSL VPN appliance. We created configuration guides to address these three common appliances. Azure MFA Server can also integrate with most other systems that use RADIUS, LDAP, IIS, or claims-based authentication to AD FS. You can find more details in Azure MFA Server configurations.

Important

As of July 1, 2019, Microsoft no longer offers MFA Server for new deployments. New customers that want to require multi-factor authentication (MFA) during sign-in events should use cloud-based Azure AD Multi-Factor Authentication.

Cisco Anyconnect Pfsense App

To get started with cloud-based MFA, see Tutorial: Secure user sign-in events with Azure AD Multi-Factor Authentication.

If you use cloud-based MFA, see Integrate your VPN infrastructure with Azure MFA.

Existing customers that activated MFA Server before July 1, 2019 can download the latest version, future updates, and generate activation credentials as usual.
