Firewall blocking all traffic

[Renan]

As soon as I enable OPNsense's packet filtering, I lose the access to the LAN connected to it from a PC in another VLAN. There are no rules inserted in the firewall, except for the standard ones. How can I gain full access with the packet filtering on?

You need pass rules to pass traffic - OPNsense blocks any traffic that is not explicitly allowed
