      @stephenw10 Hello :)
      Here is the relevant log from Firewall:

       	Mar 2 08:51:25 	HOMELAN 	USER_RULE (1613119901) 	192.168.2.247:64955		151.101.65.140:443		TCP:S
      	Mar 2 08:51:24 	HOMELAN 	USER_RULE (1613119901) 	192.168.2.247:64953		151.101.65.140:443		TCP:S 
      

      Could you please tell me where I can find the NIC log ?
      Regards!

        @myxomopec said in Software or Hardware issue?:

        At that particular network I`m not able to access reddit

        What is the pfSense IP of that network ?

        18d07b96-7c17-40ba-9101-260760369157-image.png

        What are the IP settings of the device that is using that LAN network : run ipconfig or comparable :

        ipconfig /all
        

        What is the pfSense WAN IP ?
        If it is not a RFC1918, you can hide one or two numbers.

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

            @myxomopec you are using pppoe on wan - so it might be an mss issue.

            you could try setting mss clamping on your wan to 1492 (or lower)

              @heper I`ve tried but that does not change the behavior.
              Also, from other networks I can still access reddit.

                What's the user rule that's passing that traffic? Also I assume those are pass logs? The default pass rule would not normally log.

                If it was a packet size issue you would still see the initial TCP handshake succeed. Those packets are tiny.

                  @stephenw10 Yes, We`ve dump the tcp traffic and we can see that we have response from the target IP.

                  I hope this rules you are referring to:

                    Ok so you do see a TCP handshake complete in a pcap?

                    If the first packet that fails it a large packet this probably is an MTU issue.

                    You can see re0 has a lower MTU than any other NIC. I assume you set that?

                      @stephenw10 Only my home network has MTU of 1480 ... others are by default which should be 1500 I think.

                        Exactly. I assume because you set that? And that's the subnet that cannot connect to those sites.

                          @stephenw10 OK ... So why now? This was working for year and something.

                          Here is info from dump when I try to curl reddit with 5 sec timeout:

                            Something else in the route changed probably and the PMTU discovery is failing.

                            Set the re0 NIC back to MTU 1500. Test that, it should be idebntical to the other interfaces at that point.
                            It that still fails set the MSS on that NIC to something lower, like 1452.
