Port Forwarding for Minecraft

Question

AC1900 Wifi Cable Modem RouterModel C7000v2&nbsp;I am trying to port foward for Minecraft with the port 25565.&nbsp;Service Name: MinecraftService Type: TCP/UDPExternal Start/End Port: 25565Box is checked to use the same port range for internet start/end portI'm using my PC's IPv4 address under Internal IP address.I'm using my external IP address that I find on the site&nbsp;https://www.whatismyip.com/&nbsp;&nbsp;When I pressed apply, the notice says "Invalid Data. Internal IP Address is not in LAN!"&nbsp;I even tried every the same as above ^ but instead of putting my external IP Address from&nbsp;https://www.whatismyip.com/ , I've tried putting "Any". I still get the same notice.&nbsp;What does this mean? What am I doing wrong? My apologies, I am not too tech savvy.&nbsp;&nbsp;Edit 1 : Not sure if this will make a difference (or if this relates to the issue) but I am using a Deco wifi extender (W2400 Mesh system) that is wirelessly connected to my router, and the deco is connected directly to my PC through ethernet cable. Maybe I would have to port forward my deco device as well?Edit 2: Port forwarded my deco as well, tried to port forward once again through the main router, same notice.

This image is what I see, I've seen other older threads that has a box below where you can click with IP to use, but I'm assuming that is no longer an option.

&gt; I'm using my PC's IPv4 address under Internal IP address.&nbsp;&nbsp;&nbsp; What is its address?&nbsp;&gt; I'm using my external IP address that I find on the site&gt; https://www.whatismyip.com/&nbsp;&nbsp;&nbsp; "using" how?&nbsp; The "External IP address" option in the "CustomServices" form refers to the remote client, not to anything related toyour router.&nbsp; Select "Any" for that, not any specific address.&nbsp;&gt; When I pressed apply, the notice says "Invalid Data. Internal IP&gt; Address is not in LAN!"&nbsp;&nbsp;&nbsp; I wouldn't necessarily trust that error message, but I can't see theactual data on your form, so what do I know?&gt; Edit 1 : Not sure if this will make a difference (or if this relates&gt; to the issue) but I am using a Deco wifi extender (W2400 Mesh system)&gt; that is wirelessly connected to my router, and the deco is connected&gt; directly to my PC through ethernet cable. [...]&nbsp;&nbsp;&nbsp; All I know about a Deco W2400 Mesh system is what I read on theTP-Link web site, but it's (at least typically) a router, not abrainless "wifi extender".&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; https://www.tp-link.com/us/deco-mesh-wifi/product-family/deco-w2400/&nbsp;&nbsp;&nbsp; If your Minecraft-server Windows system is connected to the Decosystem, and its IP address is on a different subnet from the C7000v2LAN, then that would explain the "not in LAN" complaint from theC7000v2.&nbsp;&nbsp;&nbsp; Are you using the wireless-router features of the C7000v2, or are allyour client devices connected to the Deco system?&gt; Edit 2: Port forwarded my deco as well, tried to port forward once&gt; again through the main router, same notice.&nbsp;&nbsp;&nbsp; Not amazing.&nbsp;&nbsp;&nbsp; You seem to have too many routers.&nbsp; That is, more than one.&nbsp; Theusual one-router options would be (1) Configure the C7000v2 as a modemonly, using the Deco router as a router, or (2) Leave the C7000v2 as amodem+router, and configure the Deco router as a wireless access point(which may or may not be possible).&nbsp; Then you'd configure the portforwarding on your remaining (one and only) router, whichever gizmo thatis.&nbsp;&nbsp;&gt; This image is what I see, [...]&nbsp;&nbsp;&nbsp; I can't (yet) see your (second) picture.&nbsp; In-line images must beapproved by a moderator before others can see them.&nbsp; The time requiredvaries.&nbsp; Attachments (as in the first posting) have no such limitation.Of course, attachments have their own one-per-message limitation.&nbsp;&gt; [...] I've seen other older threads [...]&nbsp;&nbsp;&nbsp; Thanks for the helpful links.

&gt;(2) Leave the C7000v2 as a&nbsp;modem+router, and configure the Deco router as a wireless access point(which may or may not be possible).&nbsp; Then you'd configure the port&nbsp;forwarding on your remaining (one and only) router, whichever gizmo that&nbsp;is.&nbsp;My Deco was set to router, and I've changed it to an access point. I (think) I was able to port forward properly this time? Once I changed my Deco to an access point, I was able to CMD ipconfig and my new IPv4 Address is 192.168.0.37. However, when I checked on&nbsp;https://www.canyouseeme.org/ to see if it was successful, I get the notification that "I could not see your server on *insert public IPv4* on port 25565. Reason: connetion timed out.&nbsp;&nbsp;

&gt; [...] Once I changed my Deco to an access point, I was able to CMD&gt; ipconfig and my new IPv4 Address is 192.168.0.37. [...]&nbsp;&nbsp;&nbsp; That looks like the usual C7000v2 LAN subnet.&nbsp; Now that you are downto only one router, we can worry about the other usual problems:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; https://community.netgear.com/t5/x/x/m-p/1859106&nbsp;&gt; [...] *insert public IPv4* [...]&nbsp;&nbsp;&nbsp; What _is_ that address?&nbsp; If you're worried about revealing secrets,then the top half of the address, "a.b" out of "a.b.c.d", would satisfymost of my curiosity.&nbsp; Or, plug that address into the form at:https://whois.arin.net/ , and see if it is a public or private address.&nbsp;&nbsp;&nbsp; Again, I can't (yet) see your new pictures.
