Model: TL-ER6020  
Hardware Version: V2
Firmware Version:

Hi all,

 

we are trying to combine two currently seperated networks (office & production) which are both based on TL-ER6020 routers.

 

Currently the routers are both configured as

  • Port1: WAN1 (static IP): Internet uplink / ISP
  • Port2-5: LAN

 

The general idea is to link both routers by an additionally defined WAN port and add static routing, so that both LAN networks may reach each other:

 

Router1 (Office)

  • Port1: WAN1 (static IP): Internet uplink / ISP
  • Port2: WAN2 (static IP, e.g. 192.168.30.1/24): link to Router2
  • Port3-5: LAN (e.g. 192.168.10.0/24)

 

Router2 (Production)

  • Port1: WAN1 (static IP): Internet uplink / ISP
  • Port2: WAN2 (static IP, e.g. 192.168.30.2/24): link to Router1
  • Port3-5: LAN (e.g. 192.168.20.0/24)

 

As we had some issues configuring this, should this be generally possible with the TL-ER6020's? In the end we would only allow specific hosts to use the link by filtering, but thats the next step.

 

Best,

Martin

Dear @mm_fiedler,

 

The general idea is to link both routers by an additionally defined WAN port and add static routing, so that both LAN networks may reach each other:

 

 

Unfortunately, I don't think this idea can work since the TL-ER6020 is just a NAPT device.

To make both LAN networks reach each other, why not configuring IPSec LAN-to-LAN VPN instead?

 

Here is the configuration guide for your reference, https://www.tp-link.com/support/faq/2163/
