      Hello,

      We are using pfsense to manage a public ipv6 subnet and use the pfsense as the gateway but the speed is very slow and ping is intermittent.

      We have disabled NAT so its just going via the routers as its own public IP

      We are running our pfsense vm on a proxmox host as we use multiple vlans

      we have disabled the following in the advanced settings but with no luck

      Disable hardware checksum offload
      Disable hardware TCP segmentation offload
      Disable hardware large receive offload
      Enable the ALTQ support for hn NICs.

      But have had no luck...

      If we set a ipv6 range direct on a vlan it works fine and fast without issues so the problem must be within the pfsense.

      Also i am able to ping a ipv6 via the diagnostics using a public ip and pings fine, but when from a windows servers on that ipv5 range it does not work or becomes inconsistant.

      please help...
