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?

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.

 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

I would like to get it running as it should be, could you please HELP? 

If you need more data, please feel free to ask.

 

 

 

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.
