Model: TL-ER6020  
Hardware Version: V2
Firmware Version: 2.0.2 Build 20180702 Rel.59031

Hello,
 

Is there a problem with the TL-ER6020 V2 router regarding NAT ?
It is impossible to forward a port to a server in the LAN !
I have an R600 VPN V4 router and it works directly !
Why doesn't it work with the TL-ER6020 V2 ?
I would like to be able to access from the WAN to the LAN on ports 22, 80 and 443.

 

I followed several ways of doing it on the Forum https://www.tp-link.com/en/faq-2026.html and the examples in the manual but it is impossible to function.
I do have a public address, not a private one.

Configuration:

Port Wan1 is activated and the others operate in LAN mode.
In the Transmission -> NAT -> Virtuals Servers section: ports 22, 80 and 443 are open on the TL-ER6020
Could you please provide me with the procedure to operate port forwarding ?

 

Thank you.
Yours.

@NuxBsd 

 

Only heard about ER6020 has the issue about NAT loopback.

Maybe you can access your server from your LAN at first. Make sure that the problem is not related the server. (sometimes the server may has firewall feature to block the access).

Hello,

 

Thank you for your reply.

The server works very well and is easily accessible from the WAN.

It is therefore not a firewall problem.

 

Here is the topology:

Cable modem in bridge mode -> R600 VPN V4 -> LAN The R600 VPN V4 performs forward very well.

With the TL-ER6020 V2 this does not work.

 

I opened a ticket on TP-Link support and according to them there is indeed a firmware problem.

They sent me a non-public firmware TL-ER6020v2_20180824_Beta_ClientToLanVPN.bin which I should try.
