Model: TL-ER6120  
Hardware Version: V3
Firmware Version: 3.0.2 Build 20200313 Rel.47458

Hello,

I have a setup with a TL-ER6120 router with 2 WAN used in load balacing and an IPSEC LAN-to-LAN tunnel enabled on the WAN1 interface. On the local LAN in am using addressing 192.168.1.0/24.

Using the IPSEC LAN-to-LAN I can reach the remote LAN, that has addressing 10.0.0.0/24 and remote router has local address 10.0.0.1 .

 

 

I need to reach another remote LAN, 10.0.1.0/24, that is attached and routed on the remote router 10.0.0.1 using address 10.0.1.1 .

 

I set on my local TL-ER6120 router a static route toward 10.0.1.0/24 with destination 10.0.0.1 on interface WAN1.

However, when I try to reach from my local LAN an address on the 10.0.1.0/24 class, the transmission is sent to the public WAN2 interface as I get the reply from the next-hop WAN2 router.

 

First of all, how can I manage routing toward the remote LAN attaching it to IPSEC interface and not WAN1?

Why my packet is sent to the WAN2?

 

Any help is appreciated.

I would recommend to create another IPSEC LAN-to-LAN tunnel between the 10.0.1.0/24 and 192.168.1.0/24.

 

how can I manage routing toward the remote LAN attaching it to IPSEC interface and not WAN1? Why my packet is sent to the WAN2?

 

Because of load balance feature I think. Perhaps you could try Policy Routing feature, force the traffic to the remote LAN on WAN1.
