VPNs and Firewall Rules¶
VPNs and firewall rules are handled somewhat inconsistently in pfSense® software. This section describes how firewall rules are handled for each of the individual VPN options. For the automatically added rules discussed here, the addition of those rules may be disabled by checking Disable all auto-added VPN rules under System > Advanced on the Firewall/NAT tab.
IPsec traffic coming in to the specified WAN interface is automatically allowed as described in IPsec. Traffic encapsulated within an active IPsec connection is controlled via user-defined rules on the IPsec tab under Firewall > Rules.
OpenVPN does not automatically add rules to WAN interfaces. The OpenVPN remote access VPN Wizard offers to optionally create rules to pass WAN traffic and traffic on the OpenVPN interface. Traffic encapsulated within an active OpenVPN connection is controlled via user-defined rules on the OpenVPN tab under Firewall > Rules. OpenVPN interfaces may also be assigned similar to other interfaces on pfSense. In such cases the OpenVPN tab firewall rules still apply, but there is a separate tab specific to the assigned VPN instance that controls traffic only for that one VPN.
