BGW320-500 IP Passthrough Question ( TP-LINK ER605 / Direct )

Broke down and got a TP-LINK ER605 router to try once again to get port forwarding to work.  I sort of regret 'upgrading' to fiber a couple of months back, as I've never had port forwarding issues in the past - running multiple servers...

Setup:  BGW320-500 --> ER605 --> Computer.

On the BGW320-500 side, I did a factory reset before starting anything.  Connected my computer via ethernet up to the unit to check that I could see the Internet - and all was good.

On the ER605, connected this directly up to my computer for initial setup.  While I was doing this, upgrade the firmware to the latest for my hardware version ( 2.0 and not 2.6 ).  Looked good to go, so I then powered it down and connected it to my BGW320-500.  Then connected my mac to the ER605.

The mac's firewall was disabled, just in case.

The BGW320-500 is reachable via 192.168.1.254 (i.e. default) with IP Passthrough pointing to the ER605's MAC ( which it was able to find for me - i.e. I didn't have to type it in. )

As for the ER605, I'm also able to reach this via 192.168.0.1 using my mac.  I reserved 192.168.0.100 for my mac, and in the network control panel - it does show this IP address.  In fact, the IP addr provided by ATT seems to be 'seen' by the ER605 and I'm able to 'see' it via various port forwarding check websites.

In the ER605 I added a Virtual Server with my mac's IP addr and a random port (8082) to see if I could see this. 

I've been trying things for the better part of a day and half and no luck.

Google Doc's with what I'm doing and some 'pics' that might be helpful:  https://docs.google.com/document/d/1lQyLZdRQzDumOnP4npCPmtuvbluFSOsFk_-eG3zTXQU/edit?usp=sharing

( Any sensitive info has been removed. )  Any ideas?

Could I connect my mac directly up to the BGW320-500 and attempt IP Passthrough direct?  I.e. would this allow me to be finally able to see an open port?

I probably would; however, I'm not too pleased with AT&T overall.  For example, I was quoted one price on the website, a different one when I called to set it all up, and my final price was yet a different number all together.

You really cannot make this up.

With that being said, I would more than be happy to pay to get this setup ( even though I've been running servers since the 90s myself, I really can't  understand the issues now...). But what I don't want is to get into a subscription that will last forever, and I never get my problem resolved.

So I really can't see myself 'enrolling' now - and besides, this looks like insurance for my electronics.  This was a bad idea when Circuit City tried selling me insurance on my electronics decades ago, and probably a bad idea today.

Now, if I could pay a flat fee to get this done and done - no 'enrolling', I'm all ears as I'm just too tired to continue this nonsense. 


I suspect that I'll need to continue playing with this though.

Back to my actual issue.

Question, anybody do IP Passthrough directly to one's computer?  I'm thinking of trying this out tonight to see if I can at least see a port open that way and then work my way up...

But would love to hear if anybody's tried this already.

Yes you can setup IP/Passthrough to a single computer or a router just not both at the same time.

The mac's firewall was disabled, just in case.

Make sure you enable your Mac Firewall before you try it for IP/Passthrough directly.

A couple of methods to chose from:

Well, tried the above - and I'm still getting  blocked ports when I try sites like:  yougetsignal, canyouseeme, portcheckers, etc.

Tried multiple browsers on my Mac ( latest OS ) including firefox, brave, and chrome.  I tried with the Mac Firewall on and then off.  Restarting between tries/waiting.

Then moved over to a linux NUC I'm running ( Ubuntu 20 lts) made sure that ufw was going to allow various ports, and still nothing.  I even removed the ER605 from the picture to simply the situation. First the straight up port forwarding, and then IP Passthrough directly to that computer.  Nothing.  nmap didn't show the ports as being opened as well.

Call ATT tech support - and went the person I got was wonderful.  Went through all of the above with them.  Factory restoring the gateway, trying port forwarding, then IP Passthrough - and everyone is stumped.

These websites that I've used in the past would show that they were able to see the port as being open. So I don't understand why they wouldn't work - but perhaps they show a closed port when they are in fact open?  Netstat / nmap / etc didn't seem to give me any further insights into whether or not the ports were opened either though...

Stumped.
