      Hello,

      I have a ESXi machine. I have pfSense in an VM, Debian with PiHole in another VM connected to the pfSense LAN interface.

      if I do a ping www.google.com, it resolves instantly, but there is a delay to the first ping response.
      if I do a ping from pfSense, it resolves and start receiving responses instantly.

      pfSense is using that Debian/PiHole VM for DNS requests.

      any idea?

      BR.

        I have a big delay also accessing to outlook.office.com

        While looking to the browser logs I see that there are a lot of net::ERR_CONNECTION_RESET 200 errors.

          And why would you think pfsense has anything to do with that? Are you running proxy on pfsense?

            Because when I back to my router as gateway, then connection is perfect.

                @johnpoz no.

                I have created (on ESXi):

                • one vswitch for WAN
                  pfsense address 192.168.0.2
                  gateway address 192.168.0.1 (my livebox)
                • one vswitch for LAN
                  pfsense as gateway on 10.0.0.1
                  pihole on 10.0.0.3

                I have a desktop on the livebox subnet: 192.168.0.0/24 with this configuration
                IP address 192.168.0.103
                Gateway 192.168.0.2 (pfSense)
                DNS 8.8.8.8

                and I still have the same problem, delays between name resolution and response on pings and big delay on most web accesses.

                let me know if you want screenshots from anything.

                  None of that has anything to do with what I asked.. Are you running proxy on pfsense?

                  Resolving and RTT of pings have zero to do with each other.

                    I answered 'no' to that on my previous comment in the first line.

                    I don't have too much idea about networking, sorry. I am just giving you as much information as I can.
