Cisco Anyconnect Multiple Connections

To connect to work I use Cisco AnyConnect. I do want to use multiple monitors(4) to do my work and my current graphics card does not support grouping monitors into a single one(I'm looking at upgrading sometime).

The Cisco AnyConnect Secure Mobility Client provides secure SSL and IPsec/IKEv2 connections to the ASA for remote users. Without a previously-installed client, remote users enter the IP address in their browser of an interface configured to accept SSL or IPsec/IKEv2 VPN connections.
With successful authentication, the Cisco AnyConnect application displays the message Connected to VPN Pool at the top of the screen. To disconnect and end the connection, click Disconnect. This table outlines the Duo Append Mode choices, shows specific examples, and outlines the intended action.
I do work at Cisco and yes it does. Something is turning it on without me opening any Cisco apps including any connections so this is because of Cisco not another IT department. Developer Response, AnyConnect does not automatically connect; it is only triggered by the UI or by On-Demand or Per-App VPN profiles configured on the device.

Something strange would happen when I connected to a Firepower 2130 running Firepower Threat Defense with Cisco AnyConnect.

Basically, the AnyConnect client would contact the VPN gateway just fine, prompt for user credentials, authenticate and connect but then literally after about 3 seconds of being connected it would immediately drop and attempt to reconnect again. This would typically happen about two or three times before the VPN client would make the connection and stay connected and stable. I actually never had to re-enter my user credentials during this connect / reconnect process.

While there are some topics discussed that I found by doing a couple of searches, none of them explicitly talked about Firepower 2100 series appliances, Firepower Threat Defense, or Firepower Management Center (FMC) in particular. Most articles or forum discussions were centered around ASA Firewall topics, but I think the concept behind the fix is the same.

A little bit of background regarding what device(s) are at play here:

Cisco Firepower Management Center 6.2.3.7-51 running on VMware
Cisco Firepower 2130 Next Generation Firewall on Firepower Threat Defense 6.2.3.7-51
Cisco AnyConnect Secure Mobility Client 4.5.05030 on Windows 10 64-bit

Let’s take a look at some logs to see the problem in action.

Some information seemed to point to DTLS as being the problem and while the link here suggests this on ASA releases 9.0 and 9.1, the topic of MTU size caught my eye. Teamviewer crack for mac os. Some other posts I read mentioned MTU as well, so I figured I would change the default MTU size from 1406 to something different and see if this helped, and it did.

Let’s see the problem first hand. Here are the message history logs from within Cisco AnyConnect:

What is the workaround to solve this “reconnecting” behavior?

Let’s go into FMC and change the MTU settings for the Group Policy associated with your Remote Access VPN setup. Google player for mac.

Navigate to Objects tab > VPN > Group Policy > NAME OF YOUR RA VPN GROUP POLICY > Click on the pencil “Edit” icon.

Once you are on the Edit Group Policy screen, go to the “AnyConnect” Tab > SSL Settings > Change MTU Size to 1300 Bytes.

Don’t forget to click on Save at the bottom and then deploy the changes to the firewall that AnyConnect clients are connecting to. Grab some coffee, and check the latest weather update (since FMC takes a while to push policy… ugh). Once it is done, let’s connect through VPN and take a look at those AnyConnect message history entries again.

The logs show that the VPN connection was made, and then no reconnects were tried after the successful connection. I let the client stay connected for a few minutes just to make sure everything was OK, then manually disconnected at 11:27:06. Visual studio 2013 for mac.

While leaving the MTU setting at 1300 bytes may not be possible for whatever environment you are working in, for now this seems to be working just fine. At any given time we have only about 50 concurrent AnyConnect sessions, so it’s a fairly low volume of remote workers that are being supported. If any long-term issues arise from this setup, i’ll be sure to update this post.
