Port Forwarding for Minecraft

Port Forwarding for Minecraft

AC1900 Wifi Cable Modem Router

Model C7000v2

 

I am trying to port foward for Minecraft with the port 25565. 

Service Name: Minecraft

Service Type: TCP/UDP

External Start/End Port: 25565

Box is checked to use the same port range for internet start/end port

I'm using my PC's IPv4 address under Internal IP address.

I'm using my external IP address that I find on the site https://www.whatismyip.com/ 

 

When I pressed apply, the notice says "Invalid Data. Internal IP Address is not in LAN!" 

I even tried every the same as above ^ but instead of putting my external IP Address from https://www.whatismyip.com/ , I've tried putting "Any". I still get the same notice.

 

What does this mean? What am I doing wrong? My apologies, I am not too tech savvy. 

 

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.

   What is its address?

   "using" how?  The "External IP address" option in the "Custom
Services" form refers to the remote client, not to anything related to
your router.  Select "Any" for that, not any specific address.

 

> When I pressed apply, the notice says "Invalid Data. Internal IP
> Address is not in LAN!"

 

   I wouldn't necessarily trust that error message, but I can't see the
actual data on your form, so what do I know?

   All I know about a Deco W2400 Mesh system is what I read on the
TP-Link web site, but it's (at least typically) a router, not a
brainless "wifi extender".

 

      https://www.tp-link.com/us/deco-mesh-wifi/product-family/deco-w2400/

 

   If your Minecraft-server Windows system is connected to the Deco
system, and its IP address is on a different subnet from the C7000v2
LAN, then that would explain the "not in LAN" complaint from the
C7000v2.

 

   Are you using the wireless-router features of the C7000v2, or are all
your client devices connected to the Deco system?

   Not amazing.

 

   You seem to have too many routers.  That is, more than one.  The
usual one-router options would be (1) Configure the C7000v2 as a modem
only, using the Deco router as a router, or (2) Leave the C7000v2 as a
modem+router, and configure the Deco router as a wireless access point
(which may or may not be possible).  Then you'd configure the port
forwarding on your remaining (one and only) router, whichever gizmo that
is.

   I can't (yet) see your (second) picture.  In-line images must be
approved by a moderator before others can see them.  The time required
varies.  Attachments (as in the first posting) have no such limitation.
Of course, attachments have their own one-per-message limitation.

   Thanks for the helpful links.

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 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.

   That looks like the usual C7000v2 LAN subnet.  Now that you are down
to only one router, we can worry about the other usual problems:

 

      https://community.netgear.com/t5/x/x/m-p/1859106

 

> [...] *insert public IPv4* [...]

 

   What _is_ that address?  If you're worried about revealing secrets,
then the top half of the address, "a.b" out of "a.b.c.d", would satisfy
most of my curiosity.  Or, plug that address into the form at:
https://whois.arin.net/ , and see if it is a public or private address.

 

   Again, I can't (yet) see your new pictures.
