Port forwarding Stopped working

In the past with the smart modem I have set up and used a few different ports to run servers for Minecraft and terraria and basically any game with a dedicated server download worked fine once I got them running. Coming back to play some games after having created the ports I find that all my server ports no longer work. I deleted the ports and set new ones up like I did in the past having changed but nothing will work. Has anyone had this issue and if so how have you fixed it I have tried everything i and my friend can think of to get it working and still nothing.

Was this helpful?

  • Yes it was, thank you
  • No, I still need help

Does the modem stil have a IPv4 address on the WAN and is it the same address as displayed at canyouseeme?

Have you checked that the ports are open on the device running the server. You can do this using a port checking app such as fing installed on a device connected to the local network using the local UP address of the device?

I have added the Minecraft port 25565 to allow connections to my firewall with no luck. I then checked my ports on my computer through cmd and it's not there. With the very mixed reviews, I don't really trust find enough to install it but I believe I did what the program does through cmd anyway and it's not appearing. I never had to do any of this in the past which has me stumped.

A computer update might have blocked the ports on the PC. Try reinstalling Minecraft.

I allowed the port through my firewall wouldn't that unblock it anyway?

It should unblock the the port on the PC but if the server is blocked by the firewall or the server is not listening on that port the port will appear closed.

Were did you turn on and of dynamic IP? I don't know of any settings in modem for this. There is a dynamic DNS setting that can be turned on and off.

Sorry, I have a gen 2 I forgot to include that in the title. I did it in the advanced wan services. I will try and uninstall and reinstall Minecraft but its not just Minecraft I'm having issues with.

Re: Port forwarding Stopped working

There are two versions of the Gen 2 modem. The Arcadyan and the Technicolor. Only the Technicolor has a Dynamic DNS setting and that is for setting up a dynamic DNS service. It does not effect the IP address on modem's WAN port.

 

With the Technicolor there are three places that port forwarding rules can be created. I prefer to use the settings located at Basic > Services > Port Forwarding. These rules use the IP address of the device. The other places were port forwarding can be set up use the MAC address. The MAC address can change which stops the port forwarding rule working. Some switches and extenders cause the MAC address to change. If you use a Telstra WiFi booster this can also cause the modem to see a incorrect MAC address.

Re: Port forwarding Stopped working

I have the Technicolor. I have used the basic view port forwarding in the past and it has alwase worked. I believe I have the wifi booster it come with the modem and is a 2nd box sitting next to the smart modem looking more like a standered wifi modem. I would have to assume that its the booster causing the issue as nothing else has changed. How would one go about fixing it and how do i get to my MAC settings

Try turning booster of to make sure it is the cause of the problem first.  This is what a booster looks like it should not be sitting next to smart modem.

Not what i thought it was so I don't have a booster it seems. Puts us back at the start with no clue on why the ports no longer work
