Model: ER7206 (TL-ER7206)  
Hardware Version: V1
Firmware Version: 1.0.1 Build 20210113 Rel.35468

Here's the situation:

 

I use the business router (ER7206) inside my LAN to create an isolated "sub" LAN.  

 

The setup goes like this:

 

- Brand new out of the box (which means many default settings are in effect)

 

- The WAN is on the subnet 192.168.1.x / 24

 

- The LAN is 165.26.79.x / 23

 

- The WAN port of the ER7206 is 192.168.1.204

 

- I have a Ubuntu laptop that hosts a server (SSHD) that is assigned the address 165.26.79.7 on the LAN.

 

Now...

 

- I want to port forward SSH so that I can connect to the laptop from the WAN.

 

- I've added a virtual server with the intent of port forwarding port 22 from the WAN side (e.g. ssh -p 22 user@192.168.1.204) to the laptop at 165.26.79.7

 

- I've confirmed that within the LAN, I can successfully connect to the SSHD server on the laptop (e.g. ssh -p 22 user@165.26.79.7)

 

- I've confirmed that the ER7206 is reachable from the WAN at 192.168.1.204 (ping 192.168.1.204)

 

But...

 

It just doesn't work.  Why in the name of all that is sacred is this so difficult?

 

Somebody... anybody... please help me. 

 

Thanks,

 

Louis

@Elstepherino i'm kind of going through the same issue and only have it half working but have you created the gateway acl under Network Security --> Gateway ACL? This is my current settings.

 

The problem i'm having is it takes like 30-60 seconds to eventually connect and i'm not sure why. I'm thinking it's because SSH server does a reverse look up on the IP of the source connection and it eventually timeout and let the connection though but i haven't tested it.

 

 

 

 

and my profile for SSH

No luck. I wonder if I need to do a firmware update...

@Elstepherino

Looks like you are running the controller too. I don't know if you already tried that but did you enable the SSH login and Layer-3 Accessibility?

 

Any luck with these? And what is the version of your current controller?

@Yannie I don;t think I'm running the controller.  The web interface to my router also looks very different from your screenshots.  I don;t see where I can enable Layer-3.

@Elstepherino 

 

Oh standalone mode, I thought you have the controller running.

 

Don't know why this doesn't work either...Maybe you can run the latest firmware version of this router first.

Got this from their support team:

 

Hello and thank you for contacting TP-Link support.

Upon checking your configuration screenshot, we found that your WAN IP is a private IP so you cannot set port forwarding on this router. 

Thanks for your support and cooperation, and have a nice day! 

 

 

Alrighty then...

 

I don't see why having a private WAN IP would make a difference though...
