How to Create Access Rules for Site-to-Site VPN Access

  • Last updated on

After configuring a VPN tunnel between two firewalls, you must create a Pass access rule on both systems to allow traffic through the VPN tunnel.

Create this access rule on the local and remote firewall.

Before You Begin

Create an Access Rule Allowing Traffic in and out of the VPN Tunnels

  1. Go to Firewall > Access Rules.
  2. Click Add Access Rule. The Add Access Rule window opens.
  3. Configure the access rule to match the VPN traffic:
    • Action – Select Pass.
    • Name – Enter a name for the access rule. E.g., LAN-2-VPN-SITE
    • Connection Method – Select Original Source IP.
    • Bi-Directional – Select the check box to apply the rule in both directions.
    • Source – Enter all local networks used for the VPN tunnel. 
    • Service – Select the services allowed to access the tunnel. Default: Any
    • Destination – Enter the remote networks behind the VPN tunnel, or select VPN_Networks.
  4. Click Save.
  5. Reorder the access rule by dragging it to the correct position in the Forwarding Firewall ruleset. Make sure no access rule placed above it will match the traffic for the site-to-site access rule.
