      We have a specific vlan that is being blanket blocked no matter what we do after upgrading to 2.0-RELEASE.

      We've tried deleting/recreating
      Blanket pass using a /16 subnet

      Logs still show it being blocked.

        We are going to need to get some details if we are going to help you out. Like, what is the VLAN id and the subnet? What rules are on that interface? Can we get screen shots? What outbound NAT type are you using?

          @186 pass in log quick on em0 inet from 172.25.8.0/22 to any flags S/SA keep state label "USER_RULE"

          This is what is showing up in the logs.

            @sysc:

            @186 pass in log quick on em0 inet from 172.25.8.0/22 to any flags S/SA keep state label "USER_RULE"

            This is what is showing up in the logs.

            Is that a LAN rule? There should be another tab that has the vlan rules.still need a bit more detail still.

              VLAN rule is set to allow any to any

              The above paste was actually just the log entry that is showing up for any connection from that vlan which also shows the rule.

              I should also mention that this vlan has been setup for month(s) and working until the most recent upgrade. I had been running the 2.0 ALPHA/BETA releases for 6 months.

                  I should also mention I can reach anything internal via this vlan just nothing outside of our network.

                    What are you using for your outbound nat settings?
