      LAN clients are having connectivity issues after recent reinstall.
      Whenever any client connects first time, it take long time to get internet. This happens to all client be it LAN or WLAN. Clients also looses WAN connectivity randomly.
      The CPU utilization is also high than previous install.
      I have installed Pfblocker-ng, SNORT packages. Checked all settings but didn't find any root cause.
      Pfsense Version 2.4.5-RELEASE-p1 (amd64)

        Whenever any client connects first time ....

        Using what type of network ? Wired ? Wifi ?
        Static IP addressing ? DHCP ?
        Gateway and DNS ok ?
        nslookup and ipconfig (if Windows device) confirms network settings ?

        ... doing what ? What process ?

        and removing these packages removes the issue ?
        If not, a clean setup, without using the backed up config - with just the WAN set up, if needed, removes the issue ?

        No "help me" PM's please. Use the forum, the community will thank you.
        Edit : and where are the logs ??

          It happens for both type of clients.
          My setup:
          PfSense >> Cisco SG300 switch >> Unifi AP
          I thought it might be due to some VLAN related issue, so switch is now to default L3 state. No VLAN on any device.

          Static IP addressing ? DHCP ?

          Both some devices have Static IP while others get IP from Pfsense. DHCP server configured on Pfsense

          Gateway and DNS ok ?

          Dual WAN setup, 3 Gateways configured for Load balance, and failovers, LAN rule added for 3 gatways.
          DNSSEC configured with DNS resolver.

          nslookup and ipconfig (if Windows device) confirms network settings ?

          Yes ifconfig shows all good on linux machine.

          it seems unbound is using lot of CPU

          PID USERNAME PRI NICE SIZE RES STATE C TIME WCPU COMMAND
          11 root 155 ki31 0K 32K RUN 0 15:41 36.87% [idle{idle: cpu0}]

          All working fine when i did clean re-install. All these started when I configured Pfblocker, Snort, DNSBL and DNSSEC

            Two instances of unbound - the same process, that's a bad sign.
            unbound was asked to show stats without resetting them. Takes a milli second on my system, as it just spits out some variables.
            Yours blocks doing that, stays in memory, eating up resources. That's not normal at all.

            I advise you to ditch packages right away. And be sure your settings are default - especially the DNS ones.
            Then, ok to change settings, but look closely and a long time to system behaviour between changes.
