Cisco Anyconnect Static Ip

Hi Bob, I am having issues with drop out and data corruption using my companies VPN Cisco client. I have seen you managed to help others with this issue regarding a static IP address. I've tried every setting in the router to try and fix (DMZ/port forwarding/Port clamping/firewall off/etc).

Introduction

This document describes how to configure the Cisco 5500-X Series Adaptive Security Appliance (ASA) to make the DHCP server provide the client IP address to all the Anyconnect clients with the use of the Adaptive Security Device Manager (ASDM) or CLI.

Prerequisites

Requirements

This document assumes that the ASA is fully operational and configured to allow the Cisco ASDM or CLI to make configuration changes.

Note: Refer to Book 1: Cisco ASA Series General Operations CLI Configuration Guide, 9.2 to allow the device to be remotely configured by the ASDM or Secure Shell (SSH).

Components Used

The information in this document is based on these software and hardware versions:

StaticAnyconnect

  • Cisco ASA 5500-X Next Generation Firewall Version 9.2(1)

  • Adaptive Security Device Manager Version 7.1(6)

  • Cisco Anyconnect Secure Mobility Client 3.1.05152

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

This configuration can also be used with Cisco ASA Security Appliance 5500 Series Version 7.x and later.

Background Information

Remote access VPNs address the requirement of the mobile workforce to securely connect to the organization's network. Mobile users are able to set up a secure connection using the Cisco Anyconnect Secure Mobility Client software. The Cisco Anyconnect Secure Mobility Client initiates a connection to a central site device configured to accept these requests. In this example, the central site device is an ASA 5500-X Series Adaptive Security Appliance that uses dynamic crypto maps.

In security appliance address management, you have to configure IP addresses that connect a client with a resource on the private network, through the tunnel, and let the client function as if it were directly connected to the private network.

Furthermore, you are dealing only with the private IP addresses that are assigned to clients. The IP addresses assigned to other resources on your private network are part of your network administration responsibilities, not part of VPN management. Therefore, when IP addresses are discussed here, Cisco means those IP addresses available in your private network addressing scheme that let the client function as a tunnel endpoint.

Configure

In this section, you are presented with the information to configure the features described in this document.

Note: Use the Command Lookup Tool (registered customers only) in order to obtain more information on the commands used in this section.

Network Diagram

This document uses this network setup:

Note: The IP addressing schemes used in this configuration are not legally routable on the Internet. They are RFC 1918 addresses which were used in a lab environment.

Configure Cisco Anyconnect Secure Mobility Client

ASDM Procedure

Complete these steps in order to configure the remote access VPN:

  • Enable WebVPN.
    1. Choose Configuration > Remote Access VPN > Network (Client) Access > SSL VPN Connection Profiles and under Access Interfaces, click the check boxes Allow Access and Enable DTLS for the outside interface. Also, check the Enable Cisco AnyConnect VPN Client or legacy SSL VPN Client access on the interface selected in this table check box in order to enable SSL VPN on the outside interface.
    2. Click Apply.
    3. Choose Configuration > Remote Access VPN > Network (Client) Access > Anyconnect Client Software > Add in order to add the Cisco AnyConnect VPN client image from the flash memory of ASA as shown.
      Equivalent CLI Configuration:
  • Configure Group Policy.
    1. Choose Configuration > Remote Access VPN > Network (Client) Access > Group Policies in order to create an internal group policy clientgroup. Under the General tab, select the SSL VPN Client check box in order to enable the SSL as tunneling protocol.
    2. Configure the DHCP Network-Scope in the Servers tab, choose More Options in order to configure the DHCP Scope for the users to be assigned automatically.
      Equivalent CLI Configuration:
  • Choose Configuration > Remote Access VPN > AAA/Local Users > Local Users > Add in order to create a new user account ssluser1. Click OK and then Apply.

    Equivalent CLI Configuration:

  • Configure Tunnel Group.
    1. Choose Configuration > Remote Access VPN > Network (Client) Access > Anyconnect Connection Profiles > Add in order to create a new tunnel group sslgroup.
    2. In the Basic tab, you can perform the list of configurations as shown:
      • Name the Tunnel group as sslgroup.
      • Provide the DHCP server IP address in the space provided for DHCP Servers.
      • Under Default Group Policy, choose the group policy clientgroup from the Group Policy drop-down list.
      • Configure DHCP Link or DHCP Subnet.

    3. Under the Advanced > Group Alias/Group URL tab, specify the group alias name as sslgroup_users and click OK.
      Equivalent CLI Configuration:

Subnet-Selection or Link-Selection

DHCP Proxy support for RFC 3011 and RFC 3527 is a feature introduced in the 8.0.5 and 8.2.2 and it has been supported in onward releases.

  • RFC 3011 defines a new DHCP option, the subnet selection option, which allows the DHCP client to specify the subnet on which to allocate an address. This option takes precedence over the method that the DHCP server uses to determine the subnet on which to select an address.
  • RFC 3527 defines a new DHCP suboption, the link selection suboption, which allows the DHCP client to specify the address to which the DHCP Server should respond.

In terms of the ASA, these RFCs will allow a user to specify a dhcp-network-scope for DHCP Address Assignment that is not local to the ASA, and the DHCP Server will still be able to reply directly to the interface of the ASA. The diagrams below should help to illustrate the new behavior. This will allow the use non-local scopes without having to create a static route for that scope in their network.

When RFC 3011 or RFC 3527 is not enabled, the DHCP Proxy exchange looks similar to this:

With either of these RFCs enabled, the exchange looks similar to this instead, and the VPN client is still assigned an address in the correct subnet:

Configure the ASA with Use of the CLI

Complete these steps in order to configure the DHCP server to provide IP address to the VPN clients from the command line. Refer to Cisco ASA 5500 Series Adaptive Security Appliances-Command References for more information on each command that is used.

VPN Use During Temporary Remote Work Directives Spring 2020

In response to the surge in remote workers, IT Services has significantly upgraded the capacity and performance of the VPN service. As such you should feel free to rely on the VPN anytime you are working remotely. When connected to the VPN using the 2-Step Secured - allthruucsd group, all of the traffic to and from your home or remote computer has malware filtered exactly as any on-campus computer does. However, the VPN should not be used when you are not working, such as when a family member is using your personal computer. Note that most academic and student services do not not require you to be logged in to VPN. Faculty and staff are encouraged to use the VPN when working on administrative activities. Find information on VPN setup.

These services require VPN:

Cisco
  • Shared Network Drives
  • Cognos/Tableau
  • Remote Desktop to computers or VMs
  • TN3270 (IFIS/ISIS)
  • Library resources (requires 2-Step Secured - allthruucsd)
  • Staging links to preview CMS websites (requires 2-Step Secured - allthruucsd)
  • Canvas does not require VPN but is recommended if connecting outside the U.S.
  • AccessLink
  • TechWiki
  • Some department-specific applications (iDocs, BAMTRAC, CRIS)


The UCSD VPN creates a virtual private connection over public networks using encryption and other security checks to help protect against computer data transmission interception. It also helps ensure only authorized users can access campus networks. With VPN, network computing traffic between your remote machine (off-campus or wireless) and campus passes over a single, encrypted connection, and your remote machine has a UCSD IP address.

Two-step login is required for VPN connections. Learn more about VPN and two-step login.
