      No, but sure makes it easier to read! ;)

      And doesn't make stuff look like links that are not suppose to be... When you see stuff like guys.so - you look like a spammer trying to get hits on links in some seo nonsense spammer idea.

      I was this close to just banning you and deleting the thread because with the links looked like spammer post, until I saw you were not a one post wonder and took a look to where the links were going.

        If in the unlikely event you are natting your clients make sure you also remove any existing states for those IP addresses after you add their IP to the blocking alias etc.

          ^ very true.. But even if you don't not like they would be going to any new sessions.. So while sure if they had session open to google when you blocked, they wouldn't be able to create new connection to cnn for example.

          BTW @conor are you running that many boxes on 2.4.2 code? Or are you just not able to update your sig?

            Haven't bothered to update the signature, running more than that now anyway.

                Here you go - for fun, took 2 minutes to setup..

                I created basic html page on one of my local boxes 192.168.3.32 running nginx (httpd)

                Then created a port forward, with source only my boxes IP 192.168.9.100 to send 80 traffic to 3.32..

                Made sure the rule on the network client connected to (lan in my case) was top of the list.. And there you go try to go to some http site and get the website instead..

                redirect.png

                Not going to work with https, because they would get error on cert not matching... But you could just block https..

                  Kindly explain where i should put this. Because it seems not to block the Ip addresses. Thank you

                      sure seems to be blocking show 1.17MB of hits on it already

                      Also your dns rule, should also allow tcp.. And should really be lan address, not the whole net.

                      And just to be curious - why do you block paying customers from using whatever dns they want?

                              spamming - ie sending emails is not dns queries.
