@Hank21 Hello , I see you're following with conscientious the Business router postings.

Any clue about my Issue ?

is it maybe related to firmware from the ER8411 or worse with the one from SDN 5.7.6 ?

  @Pascal 

 

it seems like this is a controller bug, I have v 5.9.9 and get the same error on the ER605,v1,v2 ER7206 and ER8411 sites

 

Does this fix will be for the Router ? as I got no real translation ports correctly opened (according my range ports needs) if I use the Router in Stand Alone mode... I was thinking that in Stand Alone mode the router don't get anything to do with Controller version.... Do you mean that Controller V5.9.3 will provide Firmware release for the router ?

  @shberge 

 

OK, then it can be a SDN firmware issue AND in the same time a firmware Device Router Issue

because I got the problem with the router in STAND ALONE mode too.

 

do you have possibility to test your ER8411 v1.0.2 in stand alone mode ?

 

 

Dear  @Hank21 

 

Can you please explain to me how a update of the SDN controller will fix an issue with a router in STAND ALONE mode ?

I'm afraid we are loosing time with just a focus on the  SDN firmware if the router still use a bugy firmware.

How a Router can be correctly manage by a controller if he is already in trouble in stand alone modus ?

 

Can TP-Link be fair and give to me the exact development's state of the ER8411 ?

This device, already on the market from months, and apparently don't look to be ready to work in production environment even less to manage entreprise network .

 

We didn't purshase the ER8411 to participate at his development, and the device is not officialy sale as a BETA device.

 

I understand well there can be some cosmetics addons or small development afterwall or securities holes that can be fixe after 

but here we are on a BASIC fonction of routing that make this router non-productive and useless without the  ports forwarding.

 

I opened this post just after sent a request ticket support to TP-Link NL, and BOTH replies are claerly not proffesionals answers:

 

The email support is now clearly hide theymself to the fact I posted on the community forum and give you the entiere responsability to manage my case.

And you are replying that my issue will be fix with a update of controller, here controller that have nothing to do with the device himself.

 

I would preferd heard that TP-Link will investigate the issue and provide a fast answer in term of fixing the Device issue or propose a hardware exchange for deffectousity

but here i feel and maybe misunderstand that we are on the wrong way and really not with a professional support to make the HIGH LEVEL ENTREPRISE ROUTER TO SHINE AS AN EXCELLENCE IN PERFORMANCE AND RELIABLE NETWORK DEVICE ON SITE.

 

May I still give an hope that I will have a real support with our ER8411 issue ?

 

Warms Regards,

  @Pascal 

 

sorry, I don't have the opportunity to test in stand alone, 

it is sad that there should be so many problems with the so-called enterprice router. it doesn't seem like tp-link cares that much either, they don't do much to fix all the bugs.

  @Pascal 

After more test and despite the possibility to got Teamviewer help with TP-Link support due to a +8 GMT forks proposal from them,

and production site can't be interrupted during daytime GMT+2,

I can confirm more details about the issue.

UDP port only translation give a randomly mapping for the internal IP.

I don't get a Ful Cone NAT with the ER8411 and it's look like an internal firewal issue from the ER8411.

 

If I put back my TL-ER6120, No issue at all with my test.

 

here are the test results with ER8411:

First with UDP 9000-10999

et its going like that til 10999 Port

 

Now testing only one port at once

retest port 5060 after few seconds and here is

after a minute next test 5060 again another mapping ...etc...

same with port UDP 5090

etc...

 

 

Now here are the results test done with TL-ER6120:

With UDP 9000>>>

With UDP5090 and 5060, all fine too

 

 

Made test with NMAP too and

both routers open the externals UDP ports but I didn't find a way to check the internal port mapping with NMAP.

 

So I'm stock with a ER8411 that give issue that compromise the usage of services from outside the Lan to inside the lan with UDP range mapping ports.

 

 

 

 

 

 

 

 

  @Pascal 

have you tried the new firmware that came out yesterday?
ver 1.0.3 is available for download
