port forwarding

It's a classic post, I know... Let me put down the basics: ASUS RT-AC66U B1 Router Firmware: 3.0.0.4.386_48262 Router WAN IP is the same as external IP (ie not CGNAT) Attempting to port forward for Home Assistant on RaspPi, port 8123 Rule as follows Internal Port should mirror External Port...

So I currently have the ASUS RT-AC3100, however I have hit a roadblock. Whenever I turn on port forwarding and put in the port it doesn't work. UPNP works but specifying a manual port just doesn't work. Anyone know what's going on? I have a public IP address, and my isp doesn't block ports. I'm...

I use a VPN service provider (similar to NordVPN etc), which offers port forwarding (opening ports). My understanding is that this is beneficial for some applications, such as BitTorrent. However, I am trying to understand what the functionality of opening ports actually accomplishes...

After upgrading to 386.1_2 (from a version that was at least a year old) port forwarding (on some non-standard ports, not sure if that matters) broke, until I disabled HW NAT acceleration (i.e. set it to “Disable” from “Auto”). The way it broke was that I could make the TCP connection (from...

I'm on RT-AX86U, and I'm experiencing an issue where the moment I add a Game Profile Open NAT > Game Profile, my existing Port Forwarding rules seem to break and my ports become inaccessible from the outside of my network. When I remove all Game Profiles and Apply, everything goes back to...

I recently purchased an ASUS GT-AC5300. Great initial thoughts and enjoying the detail in customization. However, I have run into a simple, yet show stopping problem. Every time I toggle “Enable Port Forwarding” on, it goes through some loading animations, says “Complete” but the Complete never...

Hello, I've have had problems with our Comcast Business router for awhile now. It is a SOHO network. Randomly throughout the day the internet will suddenly drop and the router will need to get power cycled. Sometimes multiple times a day. I recently went and got the router replaced to see if...

Hi-- I have a remote location that rsyncs to a NAS on my local network. I've configured port forwarding to allow the remote location's IP address as the source IP. Unfortunately, the remote location does not have a static IP. Is there any way to use the remote location's DDNS hostname in...

I'm having a problem in getting port forwarding to work from my RT AC66U to my Windows 10 desktop over a wireless link. I've configured the desktop's wireless adapter address as 192.168.0.25 and opened some inbound ports in Windows Defender/Firewall. I'm using a VPN. On the router I've set port...

Never in my life have I had an issue forwarding ports on a router...welcome to the GT-AX11000! I've tried so many things it is borderline stupid. I am not a novice in this space, but I certainly feel like one. I'm running stock firmware 3.0.0.4.384_8011. I've rebooted, completely shut down and...

Solved... primary firewall issue, not ASUS issue.

I’m running an ASUS RT-AC1900P with Merlin WRT 384.16 firmware. I’m trying to get a Liftmaster/Chamberlain 828LM (device that enables me to open my garage door from online) gateway working. This device requires the following ports open (per...

Hello! My router is RT-AC66U_B1 (FW Merlin AC68U 384.14_2) Two openvpn servers work on it: 1. TAP. My private computer connect and works well. Receive IP 192.168.0.11 and have access to all LAN resources. On WEB interface I set - Client will use VPN to access LAN only. 2. TUN (10.16.0.0) I...

Hello, I have recently updated my RT-AC5300 Router to Asuswrt-Merlin version 384.15. I am using PIA as a VPN; my external IP starts with 199.116. The computer I am trying to add to the DMZ is wired. These settings that I am trying to get working did work before I flashed Merlin onto the...

Hi. My NAS is Qnap TS-451+ and my router is Asus GT AX-11000. Yesterday I was trying to setup a DDNS on my NAS and opened some ports and enabled UPnP on my router. When I logged into my NAS today, I saw hundreds of failed login attempts from remote IPs. I searched and found out it’s due to...

I have an Asus RT-AX88U running Merlin firmware version 384.14. The router is running an OpenVPN client which is connected to a commercial VPN provider, with a rule for routing client traffic through the tunnel (a selective routing rule) that 192.168.1.0/24 goes through the VPN. In other...

Folks, For over a long time I cannot get port forwarding work with openvpn on my RT-AC87u. If PPTP is engaged then all works but once openvpn is up all forwarding rules don't work until I write something like iptables -t nat -A PREROUTING -p tcp -i tun<num_config> --dport <incoming_port> -j...

Hello. My RT-AC3200 port forwarding isn't working. It used to work (at one point), but I think a firmware update stopped that (currently sitting at 3.0.0.4). In order to make my modem and router work together I have placed my router in the modems DMZ. I try to use transparent bridging on the...

Hi all, My apologies up front if my question or terminology is out of wack as I am a bit of a noob when it comes to this sort of stuff. Anyway I was hoping @RMerlin or someone could help with the following problem: I am running dual wan for the purpose of failover and failback as my HFC...

Hi all, Thank you all for this community and Thank You Merlin and the other contributors for the firmware fork. This summer, my port-forwarding stopped working while I am connected to my home network using the OpenVPN server. The connection looks like this: iPhone or Linux laptop running...
