- Thanks for posting your question on the forum!

When the firewall is enabled, it is important that there is an allow rule in place for the outgoing VPN selectors on the LAN policy-class and incoming VPN selectors on the WAN policy-class. This so traffic is a.) allowed through the firewall and b.) not NATted unnecessarily (potentially causing traffic not to match the selectors and therefore not being encrypted).

I would be more than happy to take a look at your configuration. Just reply to this thread with the file (please remove any sensitive information). Also, please do not hesitate to let us know if you have any further questions.

Thanks,
