      Please help with my routing problem on a L3 switch after drive with pfSense 2.6 failed. All routing was working for months prior. I have to reinstall from scratch and there is an inter-vlan connection that is not working. Basically I would like to have 2 vlans on L3 switch behaving as one vlan as a learning exercise. What am I missing?

      (working) vlan2->L3->vlan2,vlan1->pfSense->ISP
      (ping but no ssh, http) vlan2->L3->vlan1

      ACL and next hop on switch is intact. pfSense firewall LAN allows foreign vlan. pfSense interface LAN is configured with L3 switch as upstream gateway. All ports now have internet. Inter-vlan ping works. Inter-vlan http and ssh not working now but was working before and the only difference is my new manual pfSense config.

        @gjaltemba if you have vlans downstream on your L3 doing routing. Pfsense has zero to do with those vlans talking to each other.

        Pfsense wouldn't even know about those vlans. They would be connected via a transit network to pfsense. Other than any firewall rule on the transit network would need to allow for the ip ranges to be able to get to other vlans on pfsense or out to the internet.

        This is how you setup a downstream router/L3 switch doing routing

          Thank you. It was a static route that I needed. Back to normal.

          Sorry when I do not use proper network terms. Not my forte.

            Yeah you have to tell pfsense how to get to the downstream networks for sure ;)
