Allowing traffic over OpenVPN Tunnels¶
By default, all traffic is blocked from entering OpenVPN tunnels. To allow traffic from remote OpenVPN nodes to make connections to resources on the local side, firewall rules under Firewall > Rules, on the OpenVPN tab are required.
As with other aspects of the firewall, these rules will only match traffic coming into the system from the remote side, not traffic leaving from the server side, so craft the rules accordingly. In cases when pfSense® is used on both ends and traffic is required to reach between local networks on both sides, then rules are required on both firewalls.
Add an OpenVPN rule which passes all traffic as follows:
Navigate to Firewall > Rules, OpenVPN tab
Click to create a new rule at the top of the list
Set Protocol to any
Enter a Description such as
Allow all on OpenVPN
Click Apply changes
To limit the traffic to only specific sources and destinations, adjust the rule(s) as needed. A strict ruleset is more secure, but more difficult to create.
