        What is the source address of the client you are testing from?

        What is real IP address on the server you are trying to connect to?

        What port are you trying to connect to?

        How are you testing?

        What is the result?

        How many FQDNs to the WAN address are we talking about?

        Please limit your answer to one port on one server only. Fix that and you'll probably know how to fix them all.

        DO NOT set a source address/port in a port forward or firewall rule unless you KNOW you need it!

            What did you do with the Redirect IPv4 Gateway - Force all client-generated IPv4 traffic through the tunnel checkbox in the server configuration?

            If unchecked (or if you have set the equivalent of Don't pull routes in the client configuration) what are the Local Networks defined in your OpenVPN server.

            One issue at a time please. Please provide as much detail as possible. You have the benefit of being able to choose the first one / prioritize.

                  If you have Redirect IPv4 Gateway checked AND you are not telling the client not to pull routes, you do not need any custom options to push any routes. You will get two routes on the client into the tunnel 0.0.0.0/1 and 128.0.0.0/1. That covers all IPv4 addresses without clobbering the client's default route. The netmask is longer (/1 is longer than /0) so those routes are preferred in the routing table over 0.0.0.0/0.

                  With that in place, connect to the VPN and attempt a connection (a single connection like to http://10.0.1.4:10000/ (or https or whatever it is supposed to be).

                  What, exactly, happens.

                  Then go to Diagnostics > Packet Capture and set the following:

                  Interface: The interface the server is on. The 10.0.1.0/24 interface
                  Host: 10.0.10.0/24
                  Port: 10000
                  Count: 100000

                  Start

                  Test connecting to 10.0.1.4:10000 and let it fail

                  Stop the capture. What do you see?

                  If you see nothing, move the packet capture to the OpenVPN interface and do the same thing. What do you see?

                    An aside: you should not be using Custom Options to push routes. You would use the Local Networks form field that would become visible if you unchecked Redirect IPv4 Gateway

                      @PITS_King said in Can access web server externally, but not from LANs.:

                      Yes, it was ruled by Congress that it is illegal for an ISP to block ANY port.

                      You do understand they repealed net neutrality right ;)

                      The mail server running on the Virtualmin server is only handling contact forms on a publicly visible website.

                      Then you have ZERO use for an inbound 25 port..

                      Internal connectivity has ZERO to do with any port forwards.. So yeah you can forget all of those.. And have arleady stated all you have to do for internal - your firewall rules already allow all traffic, so you issue of connectivity between your vlans comes down to name resolution or host firewall.

                          Just to confirm, should I replace the 3 LAN addresses I defined in IPv4 Local Network(s) to 0.0.0.0/1 and 128.0.0.0/1 to have everything working 100%?

                          It depends on what you want. There is no one answer. It's up to you.

                          If it's working, no.

                          If you want to push routes to the other side that tell them to send all traffic to you, check Redirect IPv4 Gateway.

                          If you want to send all traffic out the OpenVPN tunnel, then that would be a Remote Network on your side instead of a Local Network Local networks push routes to clients so they send traffic to you. Remote networks add kernel routes to the local routing table that get traffic into OpenVPN to send out a tunnel.

                              Then, on to getting Snort and Suricata back up and running! :-)

                              So you have your internal working... I sure wouldn't start playing with those until you do, and you sure and the F do not need both.
