Please be gentle. I am trying to teach myself this new firewall and it is going slow. I followed all the steps found here: https://docs.opnsense.org/manual/how-tos/proxywebfilter.html and it all works fine until I get to step 6 - Disable proxy bypass. I created that and now my test computer can go nowhere. If I disable those two rules the computer can go anywhere. I have the computer set to proxy via port 3128 with the address 192.168.1.1 which is the LAN. I know this isn't a ton of details but I was hoping for a couple tips on where to start looking for the issue.
I noticed that when I had the proxy bypass rules enabled (meaning the user should not be able to bypass) I could not go to the site via browser but I was able to ping and tracert to them. That made me think DNS but that is kind of where my knowledge runs dry. Is there a link between proxy and dns? sorry if this is a stupid question.
Hello YouCanDigIt,
I believe your issue has to do with firewall rules (top rules are evaluated first, so if you put a no-bypass rule at the top nothing will go through the firewall).
