Model: ER605 (TL-R605)  
Hardware Version: V2
Firmware Version: 2.2.5 Build 20240522 Rel.75860

Greetings everyone,

I've been facing this difficulty for a long time now. I have a Client-to-LAN VPN using OpenVPN and 2 IPsec tunnels for site-to-site.

My difficulty is, when I'm connected to OpenVPN, I can't access other LAN that are connected to through VPNs with IPsec. For example:

 

Site A (Headquarters):

LAN: 192.168.1.1/24

Here I have the OpenVPN server running and the IPsec tunnels set as responders

 

Site B (Branch):

LAN: 192.168.0.1/24

Here I have the IPsec set as the initiator

 

Site C (Branch)

LAN: 192.168.2.1/24

The IPsec is also set as initiator

 

Maybe I misconfigured something, they might be working, but not in the way I need. I've already managed to make this configuration work on routers from another brand, but I can't get it to work on TP-link, this is my first time making advanced setups on a TP-link router. 

Please, I require your help in resolving this problem of mine.
