ER605 OpenVPN Reach LAN Devices

Model: ER605 (TL-R605)  
Hardware Version: V2
Firmware Version: 2.2.2 Build 20231017 Rel.68869

Hello to all,

I just bought one ER605 and the main idea is to create  OpenVPN to my home LAN and if it works correctly, I will buy other Omada devices to complete the network.

The OpenVPN Configuration was easy but with the standard configuration i can reach the ER605 but no other devices on my network, such as a printer, NAS or Home assistant.

After some tries, I set the push IP address to the same range as the LAN and like this, I can reach all devices.

 

According to good practice this configuration is not okay. Is there a different way to make this configuration.

 

Please give me some help on this.

Hi @Castro05 

Thanks for posting in our business forum.

I cannot help you with this until you offer your config and topology. If you set them correctly, you should access them with no issues.

And what is the "push IP" you refer to?

 Fun fact, VPN IP usually gets blocked by the firewall. Have you ruled out the firewall?

 Hi @Clive_A, Thanks for your answer.

This is my Topology 

 

This is My Configuration  

 

 

 

Regarding "Push IP" I mean IP POOL.

 

If I change if to a different range outside the LAN range, I can't reach the NAS or home assistant or Printer.

 

Also on the OpenVPN Client side, I Notice that in all configuration cases I receive "route addition failed ", Please see below

The ER-605 does not have any kind of openvpn logging. It's important, but not for the tp-link team. You need to set static routing on your client machine for the router's internal network or select full mode (so all internet traffic will go through the ER-605) and you will be able to see the router's internal network…

Have you tried to ping the gateway IP 192.168.10.254 while you are connected to the OVPN? When the OVPN IP Pool is placed in a different subnet.

I don't recall it would be a problem if you set the IP to a different range.
