How to Configure an Access Rule for a Client-to-Site VPN

  • Last updated on

To connect your routed client-to-site VPN to your network, you must add a forwarding access rule to direct traffic between the tunnel, the remote network, and the home network.

Before You Begin

Before creating your forwarding access rules, you need the following information:

  • The published VPN network(s)
  • The VPN client network(s)

Step 1. Create a Network Object for the Published VPN Networks

Create a custom network object for the published VPN networks. If more networks are added to published VPN networks, update the network object to reflect these changes.

  • Include Entries – For each published VPN network, enter the IP address and click + to add it to the list.

For more information, see Network Objects.

Step 2. Create a Redirect to Service Access Rule

Create a Redirect to Service access rule to redirect incoming VPN connections on the dynamic interface to the VPN server listening on the local IP address.

  1. Go to FIREWALL > Access Rules.
  2. Click Add Access Rule. The Add Access Rule window opens.
  3. Enter a Name for the rule. E.g., DynamicIP-2-VPN
  4. Specify the following settings:
    • Action – Select Redirect to Service.
    • Source – The source addresses of the traffic. E.g., Any.
    • Redirect to Service Details – Select the VPN network object.
    • Destination – Select the network object corresponding to your Internet connection type (DHCP, 3G, or DSL).

  5. Click Save.
  6. Move the access rule above the BLOCKALL rule so it is the first access rule to match incoming VPN traffic.
  7. Click Save.
