r7000 port forwarding failed

Question

Hello,&nbsp;I recently attempted to setup port forwarding on my new r7000 router and am having some trouble. I tried perusing the forums for other threads with the same issue and tried a few fixes to no avail.&nbsp;Setup:-R7000 NightHawk Router - FW&nbsp; V1.0.9.88_10.2.88-I believe I veriefied I do not have CGNAT through my ISP as whatismyip.com and my WAN IP (advanced &gt; internet port &gt; IP address) are the same 73.243.xxx.x- I have set my PC to have a static IP of 192.168.1.3- I have added udp/tcp forwarding rules for the port range I need (2456-2458) pointing to the destination 192.168.1.3- I have added windows firewall rules for inbound and oubound for the same port range.&nbsp; --- While troubleshooting since this did not work, I also have tried disabling my windows firewall entirely to test and that also did not work- I verified I have the application running so it should be listening on these ports and show open I believe&nbsp;Any help would be greatly appreciated.&nbsp;Thanks!&nbsp;

Thanks for the reply!&nbsp;Actions I believe I described below after you asked but let me know if you need more info... No error message other than a port checker shows "closed" and I can see the game hosted and can join internally from my network but my friend cannot externally.&nbsp;I set a static IP on my pc, no reservation is set in the router.&nbsp;Yes same ports for external/internal. See attached screenshot.&nbsp; After posting this thread, I tried setting these up as separate rules for each port instead of the range, but that did not help (a separate service rule for each port, 3 in total 2456 2457 and 2458. Let me know if you want to see that screenshot, can only attach 1 it seems.)&nbsp;Application is a game called Valheim - from what I found on various thread it uses the 3 above ports.&nbsp; (links to threads I checked: https://www.pcgamer.com/valheim-multiplayer-dedicated-server/ and https://www.shacknews.com/article/122720/how-to-set-up-a-valheim-dedicated-server).&nbsp;&nbsp;

&gt; [...] I can see the game hosted and can join internally from my&gt; network but my friend cannot externally.&nbsp;&nbsp;&nbsp; Using which IP address?&nbsp; See item "3".&nbsp; Test both.&nbsp;&gt; I set a static IP on my pc, no reservation is set in the router.&nbsp;&nbsp;&nbsp; The danger with that is that the DHCP server in the router couldstill grant that address to some DHCP client device.&nbsp; (Especially for alow value like ".3".)&nbsp; If you're using real static addresses, thenshrink the DHCP pool, and use only ex-pool addresses as staticaddresses.&nbsp; (For example, change ".2" - ".254" to, say, ".5" - ".254".)&nbsp;&gt; [...] See attached screenshot. [...]&nbsp;&nbsp;&nbsp; Looks ok to me.

Good morning, thanks for the reply!&nbsp;I updated my DHCP pool as recommended and shrunk it to .2 - .200 and updated my PC's static IP to .201. I then updated the port forwarding rules to point to the new internal IP address of my machine.&nbsp;So you bring up a good question, when I went to connect I was able to just join via the community server browser in game as the server was showing up there properly.&nbsp;I tried to connect via IP at 192.168.1.201:2457 and was successful. I also tried my external IP 73.243.xxx.x.:2457 and that also was successful. However a port checker still shows 2457 is closed when I am connected to the server. My friend is not on to test right now to join but I suspect he won't be able to see it if a port checker still shows it closed.&nbsp;What is interesting is that when I browse servers via the Steam server browser (note this is separate from the Valheim in game server browser) that is outlined in one of those guides I can see my game with my public IP, but it shows port 2456 being used and states server is not responding. However I confirmed my server batch file is pointing to use 2457 and confirmed I can still join via the browser in game by internal/external IP at 2457.&nbsp;&nbsp;
